Abstract
BACKGROUND Characterized by progressive hair loss due to an excessive response to androgens, androgenetic alopecia (AGA) affects up to 50% of males and females. Minoxidil is one of approved medications for AGA but inadequate responses occur in many patients. AIMS To determine whether 1565 nm non-ablative fractional laser (NAFL) could yield better therapeutic benefits for patients with AGA as compared with 5% minoxidil. METHODS Thirty patients with AGA were enrolled; they were randomly assigned into the laser or minoxidil treatment groups. For the laser treatment group, patients were treated by 1565 nm NAFL at 10 mJ, 250 spots/cm2 with 2 weeks intervals for 4 sessions in total. For the minoxidil treatment group, 1-milliliter of topical 5% minoxidil solution was applied to hair loss area twice a day. RESULTS The primary outcomes were the changes in numerous hair growth indexes at the Week 10 as compared with the baselines. Both 1565 nm NAFL and 5% minoxidil led to significantly greater hair densities and diameters in patients at the Week 10 than the baselines (p < 0.01). As compared with 5% minoxidil, 1565 nm NAFL showed significantly greater improvements in total hair number, total hair density (hair/cm2), terminal hair number, terminal hair density (hair/cm2), number of hair follicle units, and average hair number/number of hair follicle units. CONCLUSIONS Our data demonstrate that 1565 nm NAFL exhibits superior clinical efficacy in some aspects of hair growth to the topical minoxidil. It is a safe and effective modality in treating AGA.

Abstract
BACKGROUND Transepidermal drug delivery is a novel therapeutic technique to boost efficacy of topical drugs. AIM In this clinical trial we evaluate the efficacy of the combination of fractional carbon dioxide (FCO2) laser and bimatoprost solution compared to bimatoprost alone in the treatment of alopecia areata. METHODS This is a prospective intra-patient comparative randomized clinical trial on 20 patients with alopecia areata. In each participant two patches were chosen to randomly receive either topical 0.03% bimatoprost solution (twice a day for 12 weeks) alone or in combination with FCO2 laser (every 2 weeks for 12 weeks). Then response to treatment was evaluated by the measurement of the severity of alopecia tool score system (SALT) score, percentage of hair regrowth, physician assessment and patients' satisfaction. RESULTS SALT score was reduced significantly during treatment sessions and after a 3-month follow-up in both treatment groups (p = 0.000). The mean percentage of improvement in SALT score in the combination therapy and monotherapy groups were 46.43 ± 4.35% and 21.16 ± 4.06% at the end of the study and 46.42 ± 5.75% and16.11 ± 3.10% at the end of the follow-up period, respectively (p = 0.000). A general linear model of two-way analysis demonstrated a significantly superior outcome in the combination therapy group compared to the monotherapy group during time (F1.6, 13.2 = 43.8. p = 0.000). CONCLUSION Fractional ablative laser can be considered as an assistant method for enhancing of efficacy of topical drugs especially in refractory cases of patchy alopecia areata.

Abstract
BACKGROUND The purpose of this study was to investigate the protective effect of Silibinin-loaded polymeric micelles from human hair against UV-B radiation. METHODS Eight formulations with different concentrations of Silibinin, Pluronic F-127, and Labrasol-Labrafil were made by a solvent evaporation method, and the selected formulation was chosen by examining their properties like particle size and loading efficiency. Six groups of human hair, including a group that received the selected formulation, were exposed to UV-B radiation and by calculating its factors such as peak-to-valley roughness, RMS roughness, FTIR, and the amount of protein loss, the protective effect of the selected formulation was judged. RESULTS According to the results, the loading efficiency and particle size of the selected formulation were 45.34% and 43.19 nm. The Silibinin release profile had two parts, fast and slow, which were suitable for creating a drug depot on hair. Its zeta potential also confirmed the minimum electrostatic interference between the formulation and hair surface. The zeta potential of selected formulation was -5.9 mv. Examination of AFM images showed that the selected formulation was able to prevent the increase in peak-to-valley roughness and RMS roughness caused by UV-B radiation. RMS roughness after 600 h of UV radiation in Groups 5 and 6 was significantly lower than the negative control group and the amount of this factor did not differ significantly between 0 and 600, so it can be concluded that the selected formulation containing Silibinin and the positive control group was able to prevent the increase of RMS roughness and hair destruction. In other hands, the two positive control groups and the selected formulation containing Silibinin were able to effectively reduce hair protein loss. CONCLUSION Silibinin-loaded polymeric micelles were able to effectively protect hair from structural and chemical changes caused by UV-B radiation.

Abstract
Short interspersed nuclear elements (SINEs) play a key role in regulating gene expression, and SINE RNAs are involved in age-related diseases. We investigated the anti-aging effects of a genetically engineered murine SINE B1 antisense RNA (B1as RNA) and explored its mechanism of action in naturally senescent BALB/c (≥14 months) and moderately senscent C57BL/6N (≥9 months) mice. After tail vein injection, B1as RNA was available in the blood of mice for approximately 30 min, persisted for approximately 2-4 h in most detected tissues and persisted approximately 48 h in lungs. We found that treatment with B1as RNA improved stamina and promoted hair re-growth in aged mice. Treatment with B1as RNA also partially rescued the increase in mitochondrial DNA copy number in liver and spleen tissues observed in aged and moderately senescent mice. Finally, treatment with B1as RNA increased the activities of superoxide dismutase and glutathione peroxidase in aged and moderately senescent mice, reduced these animals' malondialdehyde and reactive oxygen species levels, and modulated the expression of several aging-associated genes, including Sirtuin 1, p21, p16Ink4a, p15Ink4b and p19Arf, and anti-oxidant genes (Sesn1 and Sesn 2). These data suggest that B1as RNA inhibits the aging process by enhancing antioxidant activity, promoting the scavenging of free radicals, and modulating the expression of aging-associated genes. This is the first report describing the anti-aging activity of SINE antisense RNA, which may serve as an effective nucleic acid drug for the treatment of age-related diseases.

Abstract
Glutamic acid is the main excitatory neurotransmitter acting both in the brain and in peripheral tissues. Abnormal distribution of glutamic acid receptors occurs in skin hyperproliferative conditions such as psoriasis and skin regeneration; however, the biological function of glutamic acid in the skin remains unclear. Using ex vivo, in vivo and in silico approaches, we showed that exogenous glutamic acid promotes hair growth and keratinocyte proliferation. Topical application of glutamic acid decreased the expression of genes related to apoptosis in the skin, whereas glutamic acid increased cell viability and proliferation in human keratinocyte cultures. In addition, we identified the keratinocyte glutamic acid excitotoxic concentration, providing evidence for the existence of a novel skin signalling pathway mediated by a neurotransmitter that controls keratinocyte and hair follicle proliferation. Thus, glutamic acid emerges as a component of the peripheral nervous system that acts to control cell growth in the skin. These results raise the perspective of the pharmacological and nutritional use of glutamic acid to treat skin diseases.

Abstract
Clock genes express circadian rhythms in most organs. These rhythms are organized throughout the whole body, regulated by the suprachiasmatic nucleus (SCN) in the brain. Disturbance of these clock gene expression rhythms is a risk factor for diseases such as obesity. In the present study, to explore the role of clock genes in developing diabetes, we examined the effect of streptozotocin (STZ)-induced high glucose on Period1 (Per1) gene expression rhythm in the liver and the olfactory bub (OB) in the brain. We found a drastic increase of Per1 expression in both tissues after STZ injection while blood glucose content was low. After a rapid expression peak, Per1 expression showed no rhythm. Associated with an increase of glucose content, behavior became arrhythmic. Finally, we succeeded in detecting an increase of Per1 expression in mice hair follicles on day 1 after STZ administration, before the onset of symptoms. These results show that elevated Per1 expression by STZ plays an important role in the aggravation of diabetes.

Abstract
Enhanced telomerase reverse transcriptase (TERT) levels in dermal keratinocytes can serve as a novel target for hair growth promotion. Previously, we identified fisetin using a system for screening food components that can activate the TERT promoter in HaCaT cells (keratinocytes). In the present study, we aimed to clarify the molecular basis of fisetin-induced hair growth promotion in mice. To this end, the dorsal skin of mice was treated with fisetin, and hair growth was evaluated 12 days after treatment. Histochemical analyses of fisetin-treated skin samples and HaCaT cells were performed to observe the effects of fisetin. The results showed that fisetin activated HaCaT cells by regulating the expression of various genes related to epidermogenesis, cell proliferation, hair follicle regulation, and hair cycle regulation. In addition, fisetin induced the secretion of exosomes from HaCaT cells, which activated β-catenin and mitochondria in hair follicle stem cells (HFSCs) and induced their proliferation. Moreover, these results revealed the existence of exosomes as the molecular basis of keratinocyte-HFSC interaction and showed that fisetin, along with its effects on keratinocytes, caused exosome secretion, thereby activating HFSCs. This is the first study to show that keratinocyte-derived exosomes can activate HFSCs and consequently induce hair growth.

Abstract
Increasing numbers of trans and gender diverse young people are presenting to health services seeking gender-affirming medical care. While testosterone therapy in transgender males is generally effective in inducing masculinization, some adolescents encounter barriers to accessing such treatment or may not wish to experience all the changes that usually accompany testosterone. Here, we describe the case of a 17 year old trans male who presented with gender dysphoria but was initially unable to start testosterone therapy. Due to a desire for facial hair, he was therefore treated with topical minoxidil, an easily accessible, over-the-counter medication that has been used to treat androgenic alopecia for several decades. In this case, minoxidil was applied regularly to the lower face and, after three months of treatment, he developed obvious pigmented facial hair that was sufficient to help him avoid being misgendered. The only reported side effect was excessive skin dryness. Unexpectedly, despite no direct application to other areas, there was also an increase in pigmented body hair, suggestive of systemic absorption and effect. Given its long-standing use and safety record in the management of alopecia, minoxidil might thus represent a useful treatment option for trans males who desire an increase in facial hair.

Abstract
Hair loss is a complex and multi-factorial problem that is associated with significant psychological morbidity in women. Menopausal women represent a significant percentage of those affected, since the menopausal hormonal transition can be a contributing factor. A novel nutraceutical supplement has been specifically formulated with phytoactives to improve hair growth and quality in menopausal women (Nutrafol® Women’s Balance Capsules). The objective of this 6-month, randomized, double-blind, placebo-controlled study was to assess the safety and efficacy of this oral supplement to promote hair growth in perimenopausal, menopausal, and postmenopausal women with self-perceived thinning. Subjects were randomized to the study supplement (n=40) or placebo (n=30). The primary endpoint was a statistically significant increase in the number of terminal and vellus hairs based on phototrichogram analysis. Daily intake of the nutraceutical supplement resulted in progressive and significant increase in terminal and total hair counts on days 90 (P<0.01) and 180 (P<0.01) compared to placebo. The vellus hair counts significantly increased for the active treatment group (P<0.05) by day 180 while significantly decreasing for the placebo group subjects. Hair shedding progressively and significantly decreased for the active group compared to placebo, culminating in a reduction of 32.41% by day 180 (P<0.01). The study supplement was well-tolerated.

Abstract
BACKGROUND As a traditional and typical prescription of prominently activating blood circulation to remove blood stasis, Xuefu Zhuyu decoction (XZD) consists of 15 kinds of herbal medicine. Clinical investigations have showed that XZD could significantly promote the new hair generation of alopecia areata (AA) patients characterized by Qi stagnation and blood stasis. PURPOSE The purpose of this study was executed to determine whether the mechanisms by which XZD stimulated newborn hair were related to its anti-inflammatory effects. METHODS Clinical AA individuals were recruited to confirm the efficies of XZD. High performance liquid chromatography (HPLC) analysis was performed to qualitatively and quantitatively determine the contents of 15 compounds in XZD. Schrodinger molecular docking and in vivo surface plasmon resonance (SPR) techniques were used to evaluate the potential binding properties of compounds to target proteins. C3H/HeJ mice were randomly assigned to groups control, AA, and the XZD administration (6.5, 13.0 and 26.0 g/kg/d). Except for mice in control group, all the mice in the other groups were treated with a 21-day chronic unpredictable mild stress (CUMS) induced AA. Hematoxylin-eosin (H&E) staining was performed to determine the degree of pathological damage to the skin. Enzyme-linked immunosorbent assay (ELISA) was performed to detect levels of interleukin-6 (IL-6), interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) and in serum and skin tissues. Western blot, immunohistochemistry and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) were used to examine the expression levels of IL-6, IL-1β, TNF-α and osteopontin proteins and genes in skin tissues. RESULTS XZD could visibly promote hair regeneration of AA patients. The potential active ingredients in XZD prescription included at least amygdalin, hydroxysafflor yellow A, kaempferide, ferulic acid, catalpol, verbascoside, β-ecdysone, platycodin D, paeoniflorin, naringin, neohesperidin, liquiritin, glycyrrhizic acid, saikosaponin A and saikosaponin D. The results of molecular docking and SPR analysis showed that verbascoside, liquiritin, kaempferide and amygdalin showed the best potential binding properties with IL-6, IL-1β, TNF-α and osteopontin, respectively. Pathological evaluation showed that compared with the CUMS group, the administration of XZD significantly promoted hair regeneration, evidenced by increased number of skin hair follicles in C3H/HeJ AA mice. Compared with control group, ELISA data showed that the levels of IL-6, IL-1β and TNF-α in serum and skin tissues of CUMS induced AA mice were significantly increased, while XZD administration dramatically restrained the contents of the three pro-inflammatory factors. Western blot, immunohistochemistry, and qRT-PCR results further demonstrated that XZD administration notably down-regulated the protein and gene expression levels of osteopontin, IL-6, IL-1β and TNF-α in comparation with CUMS group. CONCLUSION XZD could dramatically ameliorate CUMS-induced AA damage in the skin of C3H/HeJ mice, possibly by suppressing the levels of IL-6, IL-1β, TNF-α and osteopontin.

Abstract
Context: Although Salvia plebeia (SP) R. Brown (Labiatae) is known to possess various biological activities, the effects of SP on hair growth have not been elucidated.Objective: To investigate the hair growth potential of SP extract by using human dermal papilla cells (hDPCs) and C57BL/6 mice.Materials and methods: The entire SP plant sample was ground into powder and extracted with 99.9% methyl alcohol. Various concentrations of SP extract were added to hDPCs to evaluate the proliferation, migration, and factors related to hair growth and cycling. Effect of topical SP administration on hair regrowth was tested in vivo in male C57BL/6 mice for 21 days.Results: SP extract significantly increased the proliferation of cultured hDPCs at doses of 15.6 and 31.3 μg/mL compared to control group by 123% and 132%, respectively. Expression of hepatocyte growth factor increased while the level of TGF-β1 and SMAD2/3 decreased when treated with SP extract. At the molecular level, the extract activated Wnt/β-catenin signalling by raising β-catenin and phospho-GSK3β expression. SP extract also exerted anti-apoptotic and proliferative effects in hDPCs by increasing the Bcl-2/Bax ratio and activating cell proliferation-related proteins, ERK and Akt. Finally, the extract caused an induction of the anagen phase leading to significantly enhanced hair growth in treated male mice.Discussion and conclusion: Our results indicate that SP extract has the capacity to activate hDPCs into a proliferative state to promote hair growth. Further research is necessary to determine the bioactive components and their mechanisms of action responsible for SP-related hair growth effect.

Abstract
Hair loss is a common disease in dermatology, while the approved drugs may have unpredictable side effects. In this study, the effect of timosaponin BII extracted from Anemarrhena asphodeloides on hair growth of C57BL/6 mice was investigated by measuring the hair follicle morphology, hair growth length and area in C57BL/6 male mice, and the immunohistochemical analysis of β-catenin, Wnt3a, and Wnt10b in the dorsal skins of mice after topical application with minoxidil and timosaponin BII for 15 days. The decrease in skin brightness, the increase in the regrowing area of hair and hair follicles numbers, and the improvement of hair follicle morphology in the group applied with 0.5% timosaponin BII indicated an induction of the anagen phase in telogenic mice skin, which were comparative to the 2% minoxidil treatment. The immunohistochemical analysis detected an increase in the expression of β-catenin and Wnt10b, supporting the theory of the activation of the β-catenin/Wnt pathway was one of the pathways that are related to anagen phase induction. Anemarrhena asphodeloides is a herb commonly used for metabolic disorders in China. The present study is the first to show that the timosaponin BII, which is present at a high concentration in A. asphodeloides, promotes hair growth in C57BL/6 male mice. The results indicate that timosaponin BII may be a potential promoting agent for hair growth.

Abstract
Platelet-rich plasma (PRP) therapy has been considered as a promising treatment for androgenetic alopecia (AGA). The aim of the study was comparative evaluation of the clinical efficacy of PRP-therapy, minoxidil, and their combination in the treatment of men with AGA and to evaluate the effects of PRP on the proliferation of hair follicle (HF) cells in skin biopsy. MATERIALS AND METHODS The study involved 69 men who were divided into 3 groups who received PRP therapy, minoxidil, and their combination. The clinical efficacy of the therapy was evaluated by the dynamics of morphometric of hairs. To assess cell proliferation antibodies to β-catenin, CD34, Ki67, and to Dkk-1 were used. RESULTS PRP treatment was more effective than minoxidil therapy (p = 0.005). Complex therapy turned out to be more effective than minoxidil monotherapy (p < 0.0001) and PRP monotherapy (p = 0.007). After applying PRP the absolute and relative values of the β-catenin and CD34 expression area increased; an increase in Ki67+ index was also significant. CONCLUSIONS PRP can be considered as a treatment option for AGA. Combined PRP and minoxidil use seems promising for the treatment of AGA. PRP increase in the proliferative activity of HF cells and improves hair morphology in patients with AGA.

Abstract
The present study aimed to investigate the molecular mechanism of quercitrin, a major constituent of Hottuynia cordata extract, for its hair growth stimulating activities in cultured human dermal papilla cells (hDPCs). Quercitrin enhanced the cell viability and cellular energy metabolism in cultured hDPCs by stimulating the production of NAD(P)H and mitochondrial membrane potential (ΔΨ). The expression of Bcl2, an essential marker for anagen hair follicle and cell survival, was increased by quercitrin treatment. Quercitrin also increased the cell proliferation marker Ki67. The expression of growth factors—such as bFGF, KGF, PDGF-AA, and VEGF—were increased by quercitrin both in mRNA and protein levels. In addition, quercitrin was found to increase the phosphorylation of Akt, Erk, and CREB in cultured hDPCs, while inhibitors of MAPKs reversed the effects of quercitrin. Finally, quercitrin stimulated hair shaft growth in cultured human hair follicles. Our data obtained from present study are in line with those previously reported and demonstrate that quercitrin is (one of) the active compound(s) of Hottuynia cordata extract which showed hair growth promoting effects. It is strongly suggested that the hair growth stimulating activity of quercitrin was exerted by enhancing the cellular energy metabolism, increasing the production of growth factors via activation of MAPK/CREB signaling pathway.

Abstract
This current study investigates the facilitative effects and mechanisms of decursin, a major component of Angelica gigas Nakai (AGN), and AGN root extract on hair growth in mice. We perform high-performance liquid chromatography on AGN extract to show it contains 7.3% decursin. Hairs in mouse dorsal skin are shaved distilled in water, 0.15% decursin, and 2% AGN root extract (0.15% decursin in the diluted extract) and topically applied twice a day for 17 days. Hematoxylin and eosin staining are done to examine the morphological changes in the hair follicles. To compare the effects of decursin and AGN extract on inflammatory cytokines in the dorsal skin, Western blot analysis and immunohistochemistry for tumor necrosis factor α (TNF-α) and interleukin (IL)-1β as pro-inflammatory cytokines, and IL-4 and IL-13 as anti-inflammatory cytokines are conducted. The results show that the application of decursin and AGN extract confer effects on hair growth. Hair growth is significantly facilitated from seven days after the treatments compared to that in the control group, and completely grown hair was found 17 days after the treatments. The protein levels and immunoreactivity of TNF-α and IL-1β in this case are significantly decreased, whereas the IL-4 and IL-13 levels and immunoreactivity are significantly increased compared to those in the control group. Additionally, high-mobility group box 1, an inflammatory mediator, is elevated by the topical application of decursin and AGN extract. Taken together, the treatment of mouse dorsal skin with AGE root extract containing decursin promotes hair growth by regulating pro- and/or anti-inflammatory cytokines. We, therefore, suggest that AGN root extract as well as decursin can be utilized as materials for developing hair growth-facilitating treatments.

Abstract
Research focusing on the hair concentration of cortisol and cortisone has significantly developed over the last two decades and has huge potential to provide relevant insights into stress-related diseases. However it is not clearly understood exactly how glucocorticoid (GC) medications, which are commonly prescribed drugs particularly among older adults, may affect hair cortisol and cortisone levels. The aim of this study was to examine associations of the use of GC medications with hair cortisol and cortisone concentrations in a sample of older adults. Hair samples and data were collected from participants at Wave 3 of The Irish Longitudinal Study of Ageing (TILDA). Results showed that before and after controlling for socio-demographic, health and hair characteristics, the use of systemic GCs was associated with decreased hair cortisone (B= -0.34 95 % CI -0.53, -0.16, p < 0.001). However, the use of local GCs was associated with increased hair cortisol (B = 0.39 95 % CI 0.18, 0.61). Further analysis suggests that the latter finding may be the result of use of topical steroid creams/ointments. These data add to the scant literature on the impact of steroid medication use on hair cortisol and cortisone in non-clinical populations, providing further evidence that future hair GC studies need to consider steroid medication use.

Abstract
The hair follicle goes through repetitive cycles including anagen, catagen, and telogen. The interaction of dermal papilla cells (DPCs) and keratinocytes regulates the hair cycle and hair growth. Humanin was discovered in the surviving brain cells of patients with Alzheimer’s disease. HNG, a humanin analogue, activates cell growth, proliferation, and cell cycle progression, and it protects cells from apoptosis. This study was performed to investigate the promoting effect and action mechanisms of HNG on hair growth. HNG significantly increased DPC proliferation. HNG significantly increased hair shaft elongation in vibrissa hair follicle organ culture. In vivo experiment showed that HNG prolonged anagen duration and inhibited hair follicle cell apoptosis, indicating that HNG inhibited the transition from the anagen to catagen phase mice. Furthermore, HNG activated extracellular signal-regulated kinase (Erk)1/2, Akt, and signal transducer and activator of transcription (Stat3) within minutes and up-regulated vascular endothelial growth factor (VEGF) levels on DPCs. This means that HNG could induce the anagen phase longer by up-regulating VEGF, which is a Stat3 target gene and one of the anagen maintenance factors. HNG stimulated the anagen phase longer with VEGF up-regulation, and it prevented apoptosis by activating Erk1/2, Akt, and Stat3 signaling.

Abstract
We propose a novel keratin treatment of human hair by its aqueous mixtures with natural halloysite clay nanotubes. The loaded clay nanotubes together with free keratin produce micrometer-thick protective coating on hair. First, colloidal and structural properties of halloysite/keratin dispersions and the nanotube loaded with this protein were investigated. Above the keratin isoelectric point (pH = 4), the protein adsorption into the positive halloysite lumen is favored because of the electrostatic attractions. The ζ-potential magnitude of these core-shell particles increased from -35 (in pristine form) to -43 mV allowing for an enhanced colloidal stability (15 h at pH = 6). This keratin-clay tubule nanocomposite was used for the immersion treatment of hair. Three-dimensional-measuring laser scanning microscopy demonstrated that 50-60% of the hair surface coverage can be achieved with 1 wt % suspension application. Hair samples have been exposed to UV irradiation for times up to 72 h to explore the protection capacity of this coating by monitoring the cysteine oxidation products. The nanocomposites of halloysite and keratin prevent the deterioration of human hair as evident by significant inhibition of cysteic acid. The successful hair structure protection was also visually confirmed by atomic force microscopy and dark-field hyperspectral microscopy. The proposed formulation represents a promising strategy for a sustainable medical coating on the hair, which remediates UV irradiation stress.

Abstract
Long-term use of hair dyes has potential effects on metal content in hair. However, little research dissects the specific distribution and composition variations of the metal after dyeing. In this study, we investigated the morphological change and metallic elements content variation after dyeing. The results showed that the concentration of essential metal elements decreased, among which the Ca, K, and Na decreased sharply even above 50%. As for the heavy metal, the most significant observation is that Pb increased almost by five times after dyeing. Besides, it revealed, using scanning electron microscope coupled with energy-dispersive X-ray spectroscopy (SEM-EDS), that Pb concentrated at the outer layer of the hair. In addition, two-dimensional proton-induced X-ray emission (2D-PIXE) was applied to analyze the distribution of metallic elements along the longitudinal and cross section of the hair. The results showed that Ca and Zn distributed evenly in the hair along the longitudinal and cross section. It is the first time that 2D-PIXE is applied to analyze the metallic distribution in the hair. This method exhibits high sensitivity and can be widely used in the environmental and medical field to analyze the distribution of metallic elements.

Abstract
Hair loss affects millions of people worldwide, but currently available treatment options are often dissatisfying due to side effects or limited efficacy. Pea sprout extract has been shown to improve hair density when applied topically, but its mode of action and effectiveness upon oral administration remain unknown. Our study has now shown that the application of a fluid containing 2% pea sprout extract on a defined scalp zone of 10 volunteers enhances the expression of defined genes relevant for hair, namely fibroblast growth factor-7 (FGF7) and noggin, by 56 and 85%, respectively. Additionally, a subsequent pilot nutrition intervention study in 21 volunteers proved that pea sprout extract is also effective when consumed as dietary supplement. The daily intake of 100 mg pea sprout extract (AnaGain™ Nu) for 8 weeks significantly reduced hair loss already after 28 days of treatment (p < 0.002). No adverse events were reported. Consequently, pea sprout extract may be an effective means to safely promote hair growth and reduce hair loss in individuals experiencing excessive hair shedding.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In French Polynesia, embellishment of the hair and skin is an important cultural and everyday practice. Yet, little research has focused on traditional preparations used for beautification in this region and their potential development as innovative cosmetic ingredients. AIM OF THE STUDY In this present study we aim to assess and compile the ethnocosmetic potential of plants of French Polynesia to select and further study plants showing the most promise to be developed as anti-aging, anti-blemish and hair care products. MATERIALS AND METHODS A literature analysis of plants of the IECIC list, present in French Polynesia was conducted. The most interesting plants from a cosmetic development standpoint were selected based on four main criteria, i.e. their traditional use in Polynesian cosmetic-related preparations, their biogeographical status, their phytochemistry of cosmetic interest, and lastly their availability and absence from the UICN list. Furthermore, a preliminary screening of antioxidant and anti-inflammatory activities was also performed on several extracts obtained. RESULTS Eleven plants were chosen, and a compilation of multidisciplinary data emphasized each selected plant's potentiality. Traditional allegations showed uses ranging from dermatology such as wound healing or anti-inflammatory properties, to hair growth promoting preparations or even skin ligthening ones. Preliminary screenings were useful in narrowing the number of extracts to study. Literature-based data associated to traditional uses depicted how the remaining plants and plant parts could be developed for targeted cosmetic applications. CONCLUSIONS A prospective approach of plants used traditionally for cosmetic purposes in French Polynesia gave insight on their development potential when paired with the appropriate multidisciplinary data. The eleven plants presented show promise in being developed sustainably as natural anti-aging or hair care products and as skin brightening agents.

Abstract
CONTEXT Eclipta prostrata L. (Asteraceae) (EP) has been widely used for the treatment of skin disease in Asian traditional medicine. OBJECTIVE This study investigates the potency of EP in promoting hair growth in vivo and in vitro. MATERIALS AND METHODS C57BL/6N mice were divided into four groups (n = 4) as follows: control (topical treatment of normal saline), topical 3% minoxidil to the dorsal skin of mice for 14 days, and low (1 mg/day) and high (10 mg/day) doses of EP orally administered once a day for 14 days. Dorsal hairs of C57BL/6N mice were depilated to synchronize anagen induction. Hair growth activity was evaluated by gross and microscopic observations. Sections of dorsal skin were stained with haematoxylin and eosin. We also treated the various concentrations of EP (5, 10 and 50 μg/mL) for 24 h on the human dermal papilla cells (HDPs) and examined the effects of EP on the expression of FGF-7 and mTOR signalling. RESULTS EP enhanced the induction of anagen in the dorsal skin of mice, characterized by the appearance of inner root sheath along with hair shaft, the emergence of hair shaft through the epidermis. EP increased the expression of FGF-7, while decreased the level of FGF-5 in C57/BL6 mice. EP also increased the expression of FGF-7, activated the mTOR signalling in HDPs. DISCUSSION AND CONCLUSIONS These results suggest that EP has a potency to enhance the growth of hair follicle, promoting hair growth through regulation of FGF-7 and FGF-5.

Abstract
CONTEXT Medroxyprogesterone acetate (MPA) is a widely used progestin in feminizing hormone therapy. However, the side effects and hormonal changes elicited by this drug have never been investigated in the transgender population. OBJECTIVE We evaluated the incidence of self-reported effects among transwomen using MPA and this drug's impact on hormonal and metabolic parameters. DESIGN, SETTING, AND PARTICIPANTS We retrospectively collected data from 290 follow-up visits (FUVs) of transwomen treated at Rhode Island Hospital from January 2011 to July 2018 (mean duration of therapy 3.4 ± 1.7 years). FUVs followed regimens of estradiol (E) and spironolactone, with MPA (n = 102) or without MPA (n = 188). MAIN OUTCOME MEASURES We assessed the incidence of self-reported effects after MPA treatment. We also compared blood levels of E, testosterone, and various laboratory parameters between MPA and non-MPA groups. RESULTS Mean weighted E level was 211 ± 57 pg/mL after MPA treatment and 210 ± 31 pg/mL otherwise; this difference was nonsignificant [t(274) = 0.143, P = 0.886]. Mean weighted testosterone level was 79 ± 18 ng/dL after MPA treatment and 215 ± 29 ng/dL otherwise; testosterone levels were significantly lower in the MPA group [t(122) = 32.4, P < 0.001]. There were minimal changes in other laboratory parameters. Of 39 patients receiving MPA, 26 reported improved breast development and 11 reported decreased facial hair. Five patients experienced mood swings on MPA. CONCLUSIONS In our cohort of transwomen, we found minimal side effects, unchanged E levels, and a decline in testosterone associated with MPA, outcomes consistent with feminization. Prospective studies are needed to confirm our findings.

Abstract
Pseudo-binary mixtures of different glycolipids, four different rhamnolipids (RL) and an alkyl polyglucoside (APG), with poly(diallyl-dimethylammonium chloride) (PDADMAC) have been studied in relation to their adsorption onto negatively charged surfaces to shed light on the impact of the molecular structure of surfactants from natural sources (instead of synthetic surfactant, such as sodium laureth sulfate) on the adsorption of hair-conditioning polymers. For this purpose, the self-assembly of such mixtures in aqueous solution and their adsorption onto negatively charged surfaces mimicking the negative charge of damaged hair fibres have been studied combining experiments and self-consistent field (SCF) calculations. The results show that the specific physico-chemical properties of the surfactants (charge, number of sugar rings present in surfactant structure and length of the hydrocarbon length) play a main role in the control of the adsorption process, with the adsorption efficiency and hydration being improved in relation to conventional sulfate-based systems for mixtures of PDADMAC and glycolipids with the shortest alkyl chains. SCF calculations and Energy Dispersive X-Ray Spectroscopy (EDS) analysis on real hair confirmed such observations. The results allow one to assume that the characteristic of the surfactants, especially rhamnolipids, conditions positively the adsorption potential of polyelectrolytes in these model systems. This study provides important insights on the mechanisms underlying the performance of more complex but eco-friendly washing formulations.

Abstract
Monitoring glucocorticoids in faeces and hair is increasingly used in ecological studies and provides a powerful and minimally intrusive mean to identify physiological challenges faced by wild animals. Using a cortisol and a corticosterone immunoassays, we conducted an adrenocorticotropic (ACTH) challenge with five weekly repeated injections to validate the use of faecal glucocorticoid metabolites and hair cortisol concentration as biological markers of the HPA-axis activity in captive mountain goats (Oreamnos americanus). We also investigated the effect of endogenous (age, sex, reproductive status) and methodological (faecal sample collection date, freezing delay and hair type) variables on cortisol values using faecal and hair samples collected from marked wild mountain goats during a long-term study. The cortisol enzyme immunoassay was reliable for mountain goat faeces and hair, and was sensitive enough to detect a clear rise in glucocorticoid concentration following ACTH injections for both matrices. Age and sex had no detectable effect on faecal glucocorticoid metabolites, but hair cortisol concentration was higher in kids and yearlings than in older goats, and lower in adult males compared to adult females. Reproductive status had no detectable effect on both faecal and hair measurements. Faecal metabolite concentrations increased with sample collection date in late spring until mid-summer and decreased afterward until early fall. Guard hair had nearly twice as much cortisol per gram as undercoat hair. Prolonged delay to freezing reduced the concentration of faecal glucocorticoid metabolites, but degradation seemed limited when samples were exposed to wind and sun or when ambient temperature was low. We conclude that faeces and hair can be used as valid biomarkers of the HPA-axis activity in mountain goat provided that confounding variables are taken into account when interpreting measurements.

Abstract
Dermatology supplements, often marketed as “skin, hair, and nail” supplements, are becoming increasingly popular. However, many consumers lack an understanding of the science of dietary supplements or the specifics of the supplement industry. While certain supplements at the right dose in the right population may prove beneficial, the evidence is sparse for many supplements. In addition, the use of some supplements has resulted in serious adverse effects. From a regulatory standpoint, the US FDA recognizes dietary supplements as foods. This distinction has multiple ramifications, including the fact that manufacturers do not need to prove efficacy, safety, or quality prior to sale. Therefore, physicians and consumers must evaluate each supplement ingredient and formulation individually. This article outlines an evidence-based approach to assess dermatology supplements. As a starting point, all supplements should be evaluated for PPIES: purity, potency, interactions, efficacy, and safety.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cacumen Platycladi (CP) is the leaves of Platycladus orientalis which has been traditionally used to resist alopecia and promote hair growth. However, no study has been reported on the effects of CP on proliferation of dermal papilla cells (DPCs). And there is also no complete and systematic research on hair re-growth efficacies of CP. AIM OF THE STUDY To evaluate the hair-growth activity of their extracts on the proliferation of DPCs and the promotion of hair reproduction in C57BL/6 mice. MATERIALS AND METHODS For the DPCs, different extract fractions of CP were investigated. The hair growth effect of CP volatile oil on C57BL/6 mice was evaluated for 28 days. Meanwhile, the chemical constituents of the volatile oil from Cacumen Platycladi were isolated and identified by GC-MS. RESULTS The study showed that the extracts of CP could promote the proliferation of DPCs, and the activity of volatile oil was the best. CP volatile oil (100 μg/mL) resulted in stronger proliferation of DPCs by 239.8% compared with control (100%) and minoxidil (130.3%) during the 48 h incubation. And no obvious cytotoxic activity was observed when volatile oil was dosed up to 500 μg/mL. At different growth stages, mice treated with 0.2 g/kg CP volatile oil required shorter time than 2% minoxidil. Hair length for 0.2 g/kg CP volatile oil treated group was longer than those of minoxidil and control. Further histological observation indicated that CP volatile oil could prolonged the anagen phase of hair follicles. Moreover, thirty four components, with contents of 81.9% of the total volatile oils, were separaed and identified. CONCLUSION The CP volatile oil may have the potential therapeutic agent for the treatment of alopecia.

Abstract
Activating hair follicle stem cells (HFSCs) to promote hair follicle regrowth holds promise for hair loss therapy, while challenges still remain to develop a scenario that enables enhanced therapeutic efficiency and easy administration. Here we describe a detachable microneedle patch-mediated drug delivery system, mainly made from hair-derived keratin, for sustained delivery of HFSC activators. It was demonstrated that this microneedle device integrated with mesenchymal stem cell (MSC)-derived exosomes and a small molecular drug, UK5099, could enhance the treatment efficiency at a reduced dosage, leading to promoted pigmentation and hair regrowth within 6 days through two rounds of administration in a mouse model. This microneedle-based transdermal drug delivery approach shows augmented efficacy compared to the subcutaneous injection of exosomes and topical administration of UK5099.

Abstract
BACKGROUND The relationship between female pattern hair loss (FPHL) and androgenic hormones is not well established, but some evidence indicates oral finasteride may be efficacious in FPHL. Use of a topical formulation has been proposed to minimize unwanted effects. OBJECTIVES Our objective was to compare the efficacy and safety of topical 0.25% finasteride combined with 3% minoxidil solution and 3% minoxidil solution as monotherapy in the treatment of FPHL. METHODS This was a prospective, randomized, double-blind study in 30 postmenopausal women with FPHL. Each participant was randomized to receive either topical 0.25% finasteride combined with topical 3% minoxidil or topical 3% minoxidil solution as monotherapy for 24 weeks. To determine efficacy, the hair density and diameter was measured and global photographic assessment was conducted at baseline and 8, 16, and 24 weeks. Side effects and serum dihydrotestosterone levels were also evaluated. RESULTS By 24 weeks, hair density and diameter had increased in both groups, and finasteride/minoxidil was significantly superior to minoxidil solution in terms of hair diameter (p = 0.039). No systemic side effects were reported. However, serum dihydrotestosterone levels in the finasteride/minoxidil group significantly decreased from baseline (p = 0.016). CONCLUSION A topical combination of 0.25% finasteride and 3% minoxidil may be a promising option in the treatment of FPHL with an additional benefit of increasing hair diameter. Nevertheless, as it may be absorbed percutaneously, it should be reserved for postmenopausal women. TRIAL REGISTRATION clinicaltrials.in.th; identifier TCTR20160912002.

Abstract
The livestock industry in the western United States loses an estimated $500 million annually from livestock production losses due to poisonous plants. Poisoning of livestock by plants often goes undiagnosed because there is a lack of appropriate or available specimens for analysis. The Lupinus species represent an important toxic plant in western North America that can be toxic and/or teratogenic to livestock species due to the quinolizidine alkaloids. The objective of this study was to evaluate the potential of using earwax, hair, oral fluid, and nasal mucus as noninvasive specimens to determine livestock exposure to the teratogenic Lupinus species. Quinolizidine alkaloids were detected in these four matrices in cattle that were administered a single dose of Lupinus leucophyllus. In addition, quinolizidine alkaloids from lupine were detected in the earwax of cattle that grazed on lupine-infested rangelands. This study demonstrates the potential of earwax, hair, oral fluid, and nasal mucus as noninvasive specimens for chemical analyses to aid in the diagnosis of livestock that may have been exposed to and poisoned by plants.

Abstract
The control of bleaching reaction is important in hair bleaching and laundry detergents to ensure quality of the final product. A better understanding of the reaction mechanisms is needed to minimize product failures. 31P NMR-spectroscopy-based spin trap technique was employed to detect and quantify the free radical species that were generated in different bleaching solutions. These solutions contained the key actives in an alkaline hair colorant/bleaching product, an ammonium salt and hydrogen peroxide at pH = 10. Generally, the main radical species detected in hair oxidative coloring or bleaching processes, were hydroperoxyl/superoxide radicals HO2·/O2.-, amino radicals ·NH2 and hydroxyl radicals ·OH. Their amounts showed a variation based on the chemical composition of the bleaching systems and the metal ion content. The generation of free radicals from reactions between transition metal ions, such as copper, and hydrogen peroxide at pH = 10 was evaluated. In the absence of chelating agents, the copper ions generated a significant level of hydroxyl radicals in a Fenton-like reaction with hydrogen peroxide at pH = 10. Besides that, an increase in copper ion content led to an increase of amino radical ·NH2, whereas the concentration of superoxide radical O2·- decreased which was not yet well reported in the previous literature. The effect of chelating agents like ethylenediaminetetraacetic acid (EDTA), tetrasodium-iminodisuccinate (IDS), a mixture of basic amino acids and dicarboxylic acid on free radical formation was investigated in the presence of binary Cu2+-Ca2+ bleaching systems. As expected, in the binary Cu2+-Ca2+ ion system EDTA did not suppress hydroxyl radical formation effectively, but the mixture containing sodium succinate, lysine and arginine reduced hydroxyl radical formation, whereas IDS (nearly) completely inhibited hydroxyl radical formation. The results indicated that each bleaching solution has its characteristic performance and damage profile. Whereas the reactivity can be controlled by the usage of chelating agents.

Abstract
In present study, the interaction of a toxic (cadmium) and essential element (zinc) was determined in scalp hair of pregnant and non-pregnant women resident in a rural area of Thraparkar, Pakistan, where malnutrition is prevalent. In the malnourished group (pregnant and nonpregnant women), deficiency of the essential element (zinc) due to malnutrition and exposure of toxic metal (cadmium) via non-branded cigarette smoking and drinking groundwater were carried out. For comparative purposes, scalp hair samples were also collected from pregnant and non-pregnant women, residing in Hyderabad city, consuming municipal treated drinking water and smoking branded cigarette, termed as the reference group. The domestic treated and ground water, as well as the branded and non-branding cigarettes were analysed for cadmium (Cd). Whereas Zinc (Zn) and Cd were determined in scalp hair samples of malnutrioned and reference women. The groundwater indicated 5 to 12 fold higher levels of Cd than the WHO recommended value in drinking water. Whereas the content of Cd in locally made non-branded cigarettes was found to be two fold higher than branded cigarettes. These data indicate that the malnourished pregnant and non-pregnant smokers women group had three to four times higher levels of Cd in their scalp hair samples than those values obtained for reference non smokers. Whereas, the content of Zn in scalp hair samples of the reference women was ∼20% higher than the malnourished group.

Abstract
Tobacco smoke contains various toxic heavy metals that individuals are exposed to when they smoke. Despite the presence of heavy metals in tobacco smoke, the relationship between smoking and the accumulation of toxic metals in pregnant women after long-term exposure remains under discussion. We examined the association between long-term exposure to tobacco smoke and the accumulation of toxic metals in the hair of female participants. Our study recruited 252 women from the Shanxi and Hebei provinces of Northern China; these participants were self-reported non-active smokers, and had previously delivered healthy babies without birth defects. Scalp hair was collected and analyzed for nicotine and cotinine and five potentially toxic metals (specifically, silver, chromium, cadmium, mercury, and lead). Our results showed significant positive correlations between cotinine and four metals, including silver (r = 0.369, p < 0.001), cadmium (r = 0.185, p < 0.01), mercury (r = 0.161, p < 0.05), and lead (r = 0.243, p < 0.001). Significant positive correlations were also found between nicotine and three metals-specifically silver (r = 0.331, p < 0.001), cadmium (r = 0.176, p < 0.01), and lead (r = 0.316, p < 0.001). A logistic regression model showed significant associations between cotinine and potentially toxic metals including mercury, silver, and lead (with or without adjusting for potential confounders). We thus conclude that long-term passive smoking could potentially increase the exposure level of toxic metals including lead, silver, and mercury in our study, which are especially harmful for pregnant women and their unborn fetus.

Abstract
It is generally considered that eumelanin (EM) is photoprotective while pheomelanin (PM) is phototoxic. A recent study using a mouse model demonstrated that PM produces reactive oxygen species (ROS) that cause DNA damage and eventually lead to melanomagenesis. A biochemical study showed that PM possesses a pro-oxidant activity. PM consists of benzothiazine (BT) and benzothiazole (BZ) moieties, BT moieties being transformed to BZ moieties by heat or light. In this study, we compared the effects of ultraviolet A (UVA) irradiation using synthetic PMs with different BT to BZ ratios and using various coat color mouse hairs. We found that UVA irradiation of BZ-PM increased glutathione (GSH) depletion and generated more H₂O₂ than UVA irradiation of BT-PM. Non-irradiated controls did not exhibit strong pro-oxidant activities. Upon UVA irradiation, yellow mouse hairs oxidized GSH and produced H₂O₂ faster than black or albino mouse hairs. Next, to examine the mechanism of the pro-oxidant activity of BT-PM and BZ-PM, we examined the pro-oxidant activities of 7-(2-amino-2-carboxyethyl)-dihydro-1,4-benzothiazine-3-carboxylic acid (DHBTCA) and 6-(2-amino-2-carboxyethyl)-4-hydroxybenzothiazole (BZ-AA) as BT and BZ monomers, respectively. Their pro-oxidant activities were similar, but a large difference was seen in the effects of ROS scavengers, which suggests that the redox reactions may proceed via singlet oxygen in BZ-AA and via superoxide anions in DHBTCA. These results show that UVA enhances the pro-oxidant activity of PM, in particular BZ-PM.

Abstract
Previous studies have shown that androgenic alopecia is associated with metabolic syndrome and diabetes. However, the detailed mechanism whereby diabetes causes alopecia still remains unclear. We focused on the inflammatory response that is caused by diabetes or obesity, given that inflammation is a risk factor for hair loss. Inducible nitric oxide synthase (iNOS) is known to be upregulated under conditions of acute or chronic inflammation. To clarify the potential role of iNOS in diabetes-related alopecia, we generated obese diabetic iNOS-deficient (ob/ob; iNOS-KO mice). We observed that ob/ob; iNOS-KO mice were potentiated for the transition from telogen (rest phase) to anagen (growth phase) in the hair cycle compared with iNOS-proficient ob/ob mice. To determine the effect of nitric oxide (NO) on the hair cycle, we administered an iNOS inhibitor intraperitoneally (compound 1400 W, 10 mg/kg) or topically (10% aminoguanidine) in ob/ob mice. We observed that iNOS inhibitors promoted anagen transition in ob/ob mice. Next, we administered an NO donor (S-nitrosoglutathione, GSNO), to test whether NO has the telogen elongation effects. The NO donor was sufficient to induce telogen elongation in wild-type mice. Together, our data indicate that iNOS-derived NO plays a role in telogen elongation under the inflammatory conditions associated with diabetes in mice.

Abstract
Several pharmaceutical products have been formulated over the past decades for the treatment of male and female alopecia, and pattern baldness, but relatively few metadata on their efficacy have been published. For these reasons, the pharmaceutical and medical attention has recently focused on the discovery of new and safer remedies. Particularly, great interest has been attracted by oligomeric procyanidin bioactivity, able to promote hair epithelial cell growth as well as to induce the anagen phase. Specifically, the procyanidin B2, a dimeric derivative extracted from apples, has demonstrated to be one of the most effective and safest natural compounds in promoting hair growth, both in vitro and in humans by topical applications. By evaluating the polyphenolic content of different apple varieties, we have recently found in the apple fruits of cv Annurca (AFA), native to Southern Italy, one of the highest contents of oligomeric procyanidins, and, specifically, of procyanidin B2. Thus, in the present work we explored the in vitro bioactivity of AFA polyphenolic extract as a nutraceutical formulation, named AppleMets (AMS), highlighting its effects on the cellular keratin expression in a human experimental model of adult skin. Successively, testing the effects of AMS on hair growth and tropism in healthy subjects, we observed significant results in terms of increased hair growth, density, and keratin content, already after 2 months. This study proves for the first time the impact of apple procyanidin B2 on keratin biosynthesis in vitro, and highlights its effect as a nutraceutical on human hair growth and tropism.

Abstract
In this study, we investigated the effect and mechanism of Undariopsis peterseniana, an edible brown alga, on hair growth. The treatment of vibrissa follicles with U. peterseniana extract ex vivo for 21 days significantly increased the hair-fiber lengths. The U. peterseniana extract also significantly accelerated anagen initiation in vivo. Moreover, we found that U. peterseniana extract was able to open the KATP channel, which may contribute to increased hair growth. The U. peterseniana extract decreased 5α-reductase activity and markedly increased the proliferation of dermal papilla cells, a central regulator of the hair cycle. The U. peterseniana extract increased the levels of cell cycle proteins, such as Cyclin D1, phospho(ser780)-pRB, Cyclin E, phospho-CDK2, and CDK2. The U. peterseniana extract also increased the phosphorylation of ERK and the levels of Wnt/β-catenin signaling proteins such as glycogen synthase kinase-3β (GSK-3β) and β-catenin. These results suggested that the U. peterseniana extract had the potential to influence hair growth by dermal papilla cells proliferation through the activation of the Wnt/β-catenin and ERK pathways. We isolated a principal of the U. peterseniana extract, which was subsequently identified as apo-9'-fucoxanthinone, a trichogenic compound. The results suggested that U. peterseniana extract may have a pivotal role in the treatment of alopecia.

Abstract
BACKGROUND Androgenic hair-growth contributes to secondary gender characteristics but can be troublesome in women. Inhibiting axillary hair-growth via 5-α-reductases using the Thai medicinal plant, Curcuma aeruginosa Roxb. is an attractive treatment strategy. HYPOTHESIS/PURPOSE C. aeruginosa essential oil (CA-oil) formulated as a lotion is an efficacious and safe inhibitor of axillary hair growth. STUDY DESIGN This trial was a single center, randomized, double-blind, placebo controlled 10 weeks, intervention in 60 women (18-23 years) and 2 weeks washout with axillary hair length was the primary end-point. METHODS Bioactive-enriched essential oil of C. aeruginosa was formulated with a base lotion. All participants were pre-challenged with lotions by 4-h patch irritation tests to exclude skin reactions. Participants were randomly allocated to use either 1 or 5%w/w CA-oil lotion on one axilla and base-lotion (placebo) to the other for 10 weeks followed by placebo in both axillae for 2 weeks. Every week, the axillae were photographed to measure hair lengths, shaved, and roll-on applicators containing appropriate lotion replaced. Also, skin melanin by spectrophotometry and hair density were measured. RESULTS From weeks 5-11 of trial, 1 and 5%w/w CA-oil retarded growth by 13 ± 1.5% and 16 ± 0.9% respectively, while placebo was ineffective. CA-oil had no influence on hair density. Both concentrations of CA-oil rapidly and equally effectively brightened skin within 3 weeks which persisted 2 weeks after treatment ceased while placebo darkened the skin. Adherence appeared good as judged by consistency of lotion consumption and between axillae. Participants were satisfied with the treatment and reported reduced hairiness, freedom from any discomforts, but product odour attracted some negative comment. No adverse reactions ascribed to CA-oil were detected or reported. CONCLUSION This study points to a safe and efficacious dual action on retarding hair-growth and skin lightening by CA-oil.

Abstract
Polyglycerol (PG) is a well-known cosmetic ingredient and important precursor for the synthesis of a variety of cosmetic ingredients, such as surfactants, emulsifiers, and conditioning agents for hair and skin. When derived from renewable resources, PG can provide a more sustainable platform for the development of new ingredients with improved performance in cosmetic applications. This paper will discuss recent advances in the utilization of bio-based PG ingredients as alternatives to traditional ethoxylate chemistries for mild nonionic surfactants, substantive humectants, and micellar thickeners.

Abstract
Chemical warfare agents are an actual threat and victims' decontamination is a main concern when mass exposure occurs. Skin decontamination with current protocols has been widely documented, as well as surface decontamination. However, considering hair ability to trap chemicals in vapour phase, we investigated hair decontamination after exposure to sulphur mustard simulants methyl salicylate and 2-chloroethyl ethyl sulphide. Four decontamination protocols were tested on hair, combining showering and emergency decontamination (use of Fuller's earth or Reactive Skin Decontamination Lotion RSDL®). Both simulants were recovered from hair after treatment, but contents were significantly reduced (42-85% content allowance). Showering alone was the least efficient protocol. Concerning 2-chloroethyl ethyl sulphide, protocols did not display significant differences in decontamination efficacy. For MeS, use of emergency decontaminants significantly increased showering efficacy (10-20% rise), underlining their usefulness before thorough decontamination. Our results highlighted the need to extensively decontaminate hair after chemical exposure. Residual amounts after decontamination are challenging, as their release from hair could lead to health issues.

Abstract
The purpose of this study was to provide a new insight on the response of canines to stress exposure; the ionomic profiles of canine hair (2.8 ± 0.3 years, 15.17 ± 2.1 kg) (n = 10) was determined before and after lipopolysaccharide (LPS) injections. LPS was intramuscularly injected to induce inflammatory stress responses which were confirmed by observing increases in the level of serum cortisol, aldosterone, and inflammatory cytokines such as IL-6, IL-1β, and TNF-α. The hair contents of 17 elements were obtained by applying analytical procedures using the inductively coupled plasma mass spectrometry (ICP-MS). The following elements: sodium(Na) and potassium(K) among macro-elements, iron(Fe) and manganese(Mn) among micro-elements, and aluminum(Al), nickel(Ni), and lead(Pb) for toxic elements, showed significant increased levels with the immunological stress. The degree of increase in toxic elements was remarkable with the stress exposure. A forty-five-fold increase seen in Al accumulation with the stress exposure was noteworthy. Although mercury(Hg) and cadmium(Cd) showed decreased levels with the stress exposure, the degree was negligible compared to the level of increase. Correlation pattern between the elements was changed with the immunological stress. Toxic elements became more correlated with macro- or micro-elements than with toxic elements themselves after the stress exposure. Principal component analysis (PCA) showed that LPS challenge shifted the overall hair mineral profiles to a consistent direction changing Al and K up, even in animals with different hair mineral profiles before LPS treatment. In conclusion, the multivariate data processing and study of element distribution patterns provided new information about the ionomic response of the canine hairs to immunological stress, i.e., the ionomic profiles of canine hairs is strongly affected by the stress induced by LPS injections.

Abstract
The stress hormone, cortisol, is known to affect the function and cyclic regulation of the hair follicle. When cortisol is present at high levels it has been demonstrated to reduce the synthesis and accelerate the degradation of important skin elements, namely hyaluronan and proteoglycans by approximately 40%. The following discussion outlines the relationship between stress, cortisol, and the effect on the normal function of the hair follicle. As a result of this connection, important correlations have been established in the literature to form a basis for novel, effective treatments of stress-related hair growth disorders.<br /> Amongst various treatment methods and substances, oral supplementation with a specific bioavailable proteoglycan stands out as a promising new therapeutic treatment method.<br /><br /> <em>J Drugs Dermatol</em>. 2016;15(8):1001-1004.

Abstract
BACKGROUND Female pattern hair loss (FPHL), or androgenic alopecia, is the most common type of hair loss affecting women. It is characterised by progressive shortening of the duration of the growth phase of the hair with successive hair cycles, and progressive follicular miniaturisation with conversion of terminal to vellus hair follicles (terminal hairs are thicker and longer, while vellus hairs are soft, fine, and short). The frontal hair line may or may not be preserved. Hair loss can have a serious psychological impact on women. OBJECTIVES To determine the efficacy and safety of the available options for the treatment of female pattern hair loss in women. SEARCH METHODS We updated our searches of the following databases to July 2015: the Cochrane Skin Group Specialised Register, CENTRAL in the Cochrane Library (2015, Issue 6), MEDLINE (from 1946), EMBASE (from 1974), PsycINFO (from 1872), AMED (from 1985), LILACS (from 1982), PubMed (from 1947), and Web of Science (from 1945). We also searched five trial registries and checked the reference lists of included and excluded studies. SELECTION CRITERIA We included randomised controlled trials that assessed the efficacy of interventions for FPHL in women. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality, extracted data and carried out analyses. MAIN RESULTS We included 47 trials, with 5290 participants, of which 25 trials were new to this update. Only five trials were at 'low risk of bias', 26 were at 'unclear risk', and 16 were at 'high risk of bias'.The included trials evaluated a wide range of interventions, and 17 studies evaluated minoxidil. Pooled data from six studies indicated that a greater proportion of participants (157/593) treated with minoxidil (2% and one study with 1%) reported a moderate to marked increase in their hair regrowth when compared with placebo (77/555) (risk ratio (RR) = 1.93, 95% confidence interval (CI) 1.51 to 2.47; moderate quality evidence). These results were confirmed by the investigator-rated assessments in seven studies with 1181 participants (RR 2.35, 95% CI 1.68 to 3.28; moderate quality evidence). Only one study reported on quality of life (QoL) (260 participants), albeit inadequately (low quality evidence). There was an important increase of 13.18 in total hair count per cm² in the minoxidil group compared to the placebo group (95% CI 10.92 to 15.44; low quality evidence) in eight studies (1242 participants). There were 40/407 adverse events in the twice daily minoxidil 2% group versus 28/320 in the placebo group (RR 1.24, 95% CI 0.82 to 1.87; low quality evidence). There was also no statistically significant difference in adverse events between any of the individual concentrations against placebo.Four studies (1006 participants) evaluated minoxidil 2% versus 5%. In one study, 25/57 participants in the minoxidil 2% group experienced moderate to greatly increased hair regrowth versus 22/56 in the 5% group (RR 1.12, 95% CI 0.72 to 1.73). In another study, 209 participants experienced no difference based on a visual analogue scale (P = 0.062; low quality evidence). The assessments of the investigators based on three studies (586 participants) were in agreement with these findings (moderate quality evidence). One study assessed QoL (209 participants) and reported limited data (low quality evidence). Four trials (1006 participants) did not show a difference in number of adverse events between the two concentrations (RR 1.02, 95% CI 0.91 to 1.20; low quality evidence). Both concentrations did not show a difference in increase in total hair count at end of study in three trials with 631 participants (mean difference (MD) -2.12, 95% CI -5.47 to 1.23; low quality evidence).Three studies investigated finasteride 1 mg compared to placebo. In the finasteride group 30/67 participants experienced improvement compared to 33/70 in the placebo group (RR 0.95, 95% CI 0.66 to 1.37; low quality evidence). This was consistent with the investigators' assessments (RR 0.77, 95% CI 0.31 to 1.90; low quality evidence). QoL was not assessed. Only one study addressed adverse events (137 participants) (RR 1.03, 95% CI 0.45 to 2.34; low quality evidence). In two studies (219 participants) there was no clinically meaningful difference in change of hair count, whilst one study (12 participants) favoured finasteride (low quality evidence).Two studies (141 participants) evaluated low-level laser comb therapy compared to a sham device. According to the participants, the low-level laser comb was not more effective than the sham device (RR 1.54, 95% CI 0.96 to 2.49; and RR 1.18, 95% CI 0.74 to 1.89; moderate quality evidence). However, there was a difference in favour of low-level laser comb for change from baseline in hair count (MD 17.40, 95% CI 9.74 to 25.06; and MD 17.60, 95% CI 11.97 to 23.23; low quality evidence). These studies did not assess QoL and did not report adverse events per treatment arm and only in a generic way (low quality evidence). Low-level laser therapy against sham comparisons in two separate studies also showed an increase in total hair count but with limited further data.Single studies addressed the other comparisons and provided limited evidence of either the efficacy or safety of these interventions, or were unlikely to be examined in future trials. AUTHORS' CONCLUSIONS Although there was a predominance of included studies at unclear to high risk of bias, there was evidence to support the efficacy and safety of topical minoxidil in the treatment of FPHL (mainly moderate to low quality evidence). Furthermore, there was no difference in effect between the minoxidil 2% and 5% with the quality of evidence rated moderate to low for most outcomes. Finasteride was no more effective than placebo (low quality evidence). There were inconsistent results in the studies that evaluated laser devices (moderate to low quality evidence), but there was an improvement in total hair count measured from baseline.Further randomised controlled trials of other widely-used treatments, such as spironolactone, finasteride (different dosages), dutasteride, cyproterone acetate, and laser-based therapy are needed.
