Abstract
Frontal fibrosing alopecia (FFA) is a type of cicatricial alopecia predominantly observed in postmenopausal women, with the incidence rising since its initial description in 1994. The exact etiopathogenesis of the disease has not been completely elucidated. FFA is characterized by an inflammatory process affecting the hair follicles of the fronto-temporal hairline, leading to its gradual recession. Eyebrows, particularly the lateral parts, may also be affected. Early diagnosis and an implementation of effective therapy to limit the inflammatory process are crucial in halting disease progression. Various treatment possibilities have been reported, including anti-inflammatory and immunosuppressive agents, as well as 5-alpha-reductase inhibitors, retinoids, and antimalarial agents. The use of phototherapy and surgical procedures has also been described. However, most available data have been obtained retrospectively, frequently consisting of descriptions of case reports or small case series, and not from randomized controlled trials. In addition, the etiopathogenesis of FFA remains unclear and its course unpredictable, occasionally being linked with spontaneous stabilization. Hence, no precise guidelines exist regarding treatment modalities. Therefore, the aims of this study were to provide a comprehensive review of the efficacy of existing therapeutic modalities for FFA and to highlight novel therapeutic options.

Abstract
BACKGROUND There is speculation that some environmental factors may be impacting the increasing incidence of frontal fibrosing alopecia (FFA). In a recent publication, sensitisation to benzyl salicylate was shown to be prevalent among 36 patients with FFA. Ethylhexyl salicylate (EHS), a light stabiliser, ultraviolet (UV) B absorber and UV filter, frequently found in photoprotectors/cosmetics and, rarely reported as a sensitiser, was not patch tested in said research. METHODS From January 2021 to February 2022, 33 patients with FFA were patch-tested with the European Photopatch Series, including EHS 10% pet. in two hospitals. In addition, we conducted a literature review and a market survey. RESULTS Patch test reactions to EHS were identified in 9 of 33 (27.3%). Four of nine also reacted to their personal sunscreens (containing EHS). All involved women with a mean age of 54 (30-65). Five patients had been diagnosed with FFA before the patch tests; and, four were diagnosed with FFA during the patch test investigations. CONCLUSION Sensitisation to EHS was frequently found in a selected population of patients with FFA. We propose to expand the spectrum of contact allergens described in patients with FFA to include EHS and discuss the possible need for optimization of the patch test preparation.

Abstract
Frontal Fibrosing Alopecia (FFA) is a distinctive form of cicatricial alopecia characterized by gradual hairline recession, predominantly affecting postmenopausal individuals, thus implying a potential hormonal origin. This narrative review, spanning 2000 to 2023, delves into PubMed literature, focusing on the menopausal and hormonal status of women with FFA. The objective is to unravel the intricate nature of FFA and its plausible associations with hormonal dysregulations in women. While menopause remains a pivotal demographic characteristic linked to FFA, existing data suggest that its hormonal imbalances may not fully account for the development of FFA. Conversely, substantial evidence indicates a strong association between a reduction in fertile years, particularly through surgical interventions leading to an abrupt hormonal imbalance, and FFA in women. Additionally, exposure to hormone replacement therapy or oral contraceptives has shown varying degrees of association with FFA. Gynecologists should maintain a heightened awareness regarding the ramifications of their interventions and their pivotal role in overseeing women's fertility, recognizing the potential influence on the progression of FFA. The recurrent theme of hormonal disruption strongly implies a causal connection between alterations in sex hormones and FFA in women. Nevertheless, this relationship's extent and underlying mechanisms remain subjects of ongoing debate.

Abstract
Alopecia is comorbid with several illnesses, including various autoimmune conditions such as thyroid disease. Leukocyte-mediated inflammation of hair follicles in alopecia was first described over a century ago. However, the high prevalence of the role of thyroid autoimmune disease in the pathogenesis of alopecia has only recently come to light, together with a strong association between the two. Therefore, this review focuses on articles published between 2011 and 2022 on alopecia's association with thyroid autoimmune disease, and the mechanism behind it. In addition, it highlights the link between alopecia and thyroid cancer, as patients with alopecia have increased risk of thyroid cancer. In conclusion, this comprehensive, focused, scoping review will serve as a reference highlighting recent information on alopecia, exploring its association with thyroid autoimmune diseases.

Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) is a cicatricial alopecia affecting the frontotemporal hairline. Given that this scarring, immune-mediated follicular destruction most commonly affects postmenopausal Caucasian women, researchers have postulated that there are hormonal and genetic components; however, the etiology of FFA is still unknown. Recently, dermatologists have reported cases of FFA as being potentially caused by cosmetic products, such as sunscreen and shampoo. Therefore, this systematic review and meta-analysis intend to be the first to analyze the relationship between FFA and cosmetic/personal care products and treatments, including sunscreen, moisturizer, foundation, shampoo, conditioner, hair mousse, hair gel, hair dye, hair straightening/rebonding, chemical/laser facial resurfacing, aftershave, and facial cleanser. METHODS The Cochrane, PubMed, EMBASE, and Medline (Ovid) databases were searched for the relevant studies from the date of inception to August 2022. Case-control, cross-sectional, and cohort studies examining the effects of cosmetic/personal care product use on FFA, available in English full-text, were included. Analyses were performed using Review Manager, version 5.4. Results were reported as an odds ratio (OR) with a 95% confidence interval (CI); p values < 0.05 were considered significant. RESULTS Nine studies were included in our quantitative analyses, totaling 1,248 FFA patients and 1,459 controls. There were significant positive associations found for FFA and sunscreen (OR 3.02, 95% CI 1.67-5.47; p = 0.0003) and facial moisturizer (OR 2.20, 95% CI 1.51-3.20; p < 0.0001) use. Gender sub-analyses demonstrated a positive association for FFA and facial moisturizer in men (OR 5.07, 95% CI 1.40-18.32; p = 0.01), but not in women (OR 1.58, 95% CI 0.83-2.98; p = 0.16). Both gender sub-analyses were significantly positive for the association with facial sunscreen (Male OR 4.61, 95% CI 1.54-13.78, p = 0.006; Female OR 2.74, 95% CI 1.32-5.70, p = 0.007). There was no association found for a facial cleanser (OR 1.14, 95% CI 0.33-1.52; p = 0.51), foundation (OR 1.13, 95% CI 0.83-1.55; p = 0.21), shampoo (OR 0.49, 95% CI 0.22-1.10; p = 0.08), hair conditioner (OR 0.81, 95% CI 0.52-1.26; p = 0.35), hair mousse (OR 1.37, 95% CI 0.75-2.51; p = 0.31), and hair gel (OR 0.90, 95% CI 0.48-1.69; p = 0.74), hair dye (OR 1.07, 95% CI 0.69-1.64; p = 0.77), hair straightening/rebonding (OR 0.88, 95% CI 0.08-9.32; p = 0.92), hair perming (OR 1.41, 95% CI 0.89-2.23; p = 0.14), facial toner (OR 0.51, 95% CI 0.12-2.21; p = 0.37), or aftershave (OR 1.64, 95% CI 0.28-9.49; p = 0.58). CONCLUSIONS This meta-analysis strongly suggests that leave-on facial products, facial sunscreen and moisturizer, are associated with FFA. While the association with facial moisturizer did not persist when stratifying for female populations, gender sub-analyses remained significant for a facial sunscreen. There was no significant relationship found with hair products or treatments. These findings suggest a potential environmental etiology in the development of FFA, particularly UV-protecting chemicals.

Abstract
(1) Background: Frontal fibrosing alopecia (FFA) is a scarring alopecia that predominantly affects postmenopausal women; (2) Methods: A retrospective, observational, single-center study was conducted in the Hospital General Universitario in Ciudad Real, Spain, including all patients diagnosed with FFA between 2010 and 2021; (3) Results: A total of 306 patients (296 women and 10 men) were included in our study. The mean age of onset was 59.5 years. The severity of this disease was evenly distributed between mild (147 patients) and severe (149 patients) forms. There was a positive, statistically significant, medium correlation between the severity of the disease and its time of progression. Moreover, hypothyroidism was present in 70 patients (22.9%) and classic signs of concomitant lichen planopilaris were observed in just 30 patients (9.8%), while other forms of lichen planus were uncommon. The estimated prevalence in our population is 0.15% and the incidence is 15.47 new cases per 100,000 inhabitants; (4) Conclusions: The time of progression was positively correlated with the severity of FFA. However, the presence of clinical signs, such as inflammatory trichoscopic signs, was not associated with the progression of this condition.

Abstract
Thyroid hormones are required for the physiological growth and maintenance of hair follicles. We aim to study the thyroid profile of patients with alopecia. This is a narrative review. PubMed literature was searched from 2013 to 2022. We followed different types of alopecia: alopecia areata (AA), androgenic alopecia in males and females, telogen effluvium (TE), frontal fibrosing alopecia (FFA), lichen planopilaris, and alopecia neoplastica (AN). AA shares a common autoimmune background with autoimmune thyroid diseases, either sporadic or belonging to autoimmune polyglandular syndromes. Some data suggested that AA is more severe if thyroid anomalies are confirmed, including subclinical dysfunction or positive antithyroid antibodies with normal hormone values. However, routine thyroid screening for patients with AA, if the patients are asymptomatic from a thyroid point of view and they have negative personal and family history of autoimmunity, remains controversial. TE, apart from the autoimmune type, associates thyroid anomalies of a hormonal assay (between 5.7% and 17%). FFA, mostly a postmenopausal entity (however, not exclusive), associates a higher prevalence of thyroid conditions (up to 50%) than the general population. However, these might have an age-dependent pattern, thus the association may be incidental since there are a limited number of studies. Overall, alopecia remains a very challenging condition for patients and physicians; a multidisciplinary team is required to improve the outcome and quality of life. The common autoimmune background is suggestive of some types of alopecia and thyroid disorders, yet, the underlying mechanisms are still a matter of debate. AA, TE, FFA, LPP, and, potentially, female pattern hair loss have been found to be connected with thyroid entities, thus a state of awareness from a dual perspective, of trichology and endocrinology, is helpful.

Abstract
Photoprotection is a critical health prevention strategy to reduce the deleterious effects of ultraviolet radiation (UVR) and visible light (VL). Methods of photoprotection are reviewed in this paper, with an emphasis on sunscreen. The most appropriate sunscreen formulation for personal use depends on several factors. Active sunscreen ingredients vary in their protective effect over the UVR and VL spectrum. There are dermatologic diseases that cause photosensitivity or that are aggravated by a particular action spectrum. In these situations, sunscreen suggestions can address the specific concern. Sunscreen does not represent a single entity. Appropriate personalized sunscreen selection is critical to improve compliance and clinical outcomes. Health care providers can facilitate informed product selection with awareness of evolving sunscreen formulations and counseling patients on appropriate use. This review aims to summarize different forms of photoprotection, discuss absorption of sunscreen ingredients, possible adverse effects, and disease-specific preferences for chemical, physical or oral agents that may decrease UVR and VL harmful effects.

Abstract
Patients with frontal fibrosing alopecia report higher rates of sunscreen use than control subjects. However, it is not known whether the higher use of sunscreens is a cause or a consequence of the alopecia. A greater use of sunscreens should be associated with a lower incidence of signs of actinic damage. The aim of this study is to assess the presence of actinic damage in patients with frontal fibrosing alopecia. A cross-sectional study was carried out on 101 patients with frontal fibrosing alopecia and 40 control subjects. The presence of actinic damage, in the form of solar lentigines, actinic keratoses, and basal and squamous cell carcinomas, was recorded in both groups, together with sunscreen use. Trichoscopy and skin biopsy were performed on patients. Actinic damage was present more frequently in patients with frontal fibrosing alopecia (69.3%) than in control subjects (50%) (p = 0.031). Patients used sunscreens more frequently than did control subjects (83.2% vs 62.5%, p = 0.008). However, the prevalence of trichoscopic inflammatory signs, peripheral alopecia, and inflammatory infiltrate and sebaceous gland involvement in skin biopsy, were similar in patients who used sunscreens and those who did not use them. In conclusion, patients with frontal fibrosing alopecia had greater actinic damage than did control subjects, and this is hypothesized as a reason for the higher use of sunscreens among patients. Thus, use of sunscreens may not be the trigger for frontal fibrosing alopecia that dermatologists have proposed.

Abstract
Frontal fibrosing alopecia (FFA) is a primary patterned cicatricial alopecia that mostly affects postmenopausal women and causes frontotemporal hairline regression and eyebrow loss. Although the incidence of FFA has increased worldwide over the last decade, its etiology and pathology are still unclear. We cover the latest findings on its pathophysiology, including immunomodulation, neurogenic inflammation, and genetic regulation, to provide more alternatives for current clinical treatment. A persistent inflammatory response and immune privilege (IP) collapse develop and lead to epithelial hair follicle stem cells (eHFSCs) destruction and epithelial-mesenchymal transition (EMT) in the bulge area, which is the key process in FFA pathogenesis. Eventually, fibrous tissue replaces normal epithelial tissue and fills the entire hair follicle (HF). In addition, some familial reports and genome-wide association studies suggest a genetic susceptibility or epigenetic mechanism for the onset of FFA. The incidence of FFA increases sharply in postmenopausal women, and many FFA patients also suffer from female pattern hair loss in clinical observation, which suggests a potential association between FFA and steroid hormones. Sun exposure and topical allergens may also be triggers of FFA, but this conjecture has not been proven. More evidence and cohort studies are needed to help us understand the pathogenesis of this disease.

Abstract
The primary forms of cicatricial (scarring) alopecia (PCA) are a group of inflammatory, irreversible hair loss disorders characterized by immune cell infiltrates targeting hair follicles (HFs). Lichen planopilaris (LPP), frontal fibrosing alopecia (FFA), and centrifugal cicatricial alopecia (CCCA) are among the main subtypes of PCAs. The pathogenesis of the different types of PCAs are poorly understood, and current treatment regimens yield inconsistent and unsatisfactory results. We performed high-throughput RNA-sequencing on scalp biopsies of a large cohort PCA patients to develop gene expression-based signatures, trained into machine-learning-based predictive models and pathways associated with dysregulated gene expression. We performed morphological and cytokine analysis to define the immune cell populations found in PCA subtypes. We identified a common PCA gene signature that was shared between LPP, FFA, and CCCA, which revealed a significant over-representation of mast cell (MC) genes, as well as downregulation of cholesterogenic pathways and upregulation of fibrosis and immune signaling genes. Immunohistological analyses revealed an increased presence of MCs in PCAs lesions. Our gene expression analyses revealed common pathways associated with PCAs, with a strong association with MCs. The indistinguishable differences in gene expression profiles and immune cell signatures between LPP, FFA, and CCCA suggest that similar treatment regimens may be effective in treating these irreversible forms of hair loss.

Abstract
Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are primary, lymphocytic cicatricial hair loss disorders. These model epithelial stem cell (SC) diseases are thought to result from a CD8+ T-cell‒dominated immune attack on the hair follicle (HF) SC niche (bulge) after the latter has lost its immune privilege (IP) for as yet unknown reasons. This induces both apoptosis and pathological epithelial‒mesenchymal transition in epithelial SCs, thus depletes the bulge, causes fibrosis, and ultimately abrogates the HFs' capacity to regenerate. In this paper, we synthesize recent progress in LPP and FFA pathobiology research, integrate our limited current understanding of the roles that genetic, hormonal, environmental, and other factors may play, and define major open questions. We propose that LPP and FFA share a common initial pathobiology, which then bifurcates into two distinct clinical phenotypes, with macrophages possibly playing a key role in phenotype determination. As particularly promising translational research avenues toward direly needed progress in the management of these disfiguring, deeply distressful cicatricial alopecia variants, we advocate to focus on the development of bulge IP and epithelial SC protectants such as, for example, topically effective, HF‒penetrating and immunoinhibitory preparations that contain tacrolimus, peroxisome proliferator-activated receptor-γ, and/or CB1 agonists.

Abstract
INTRODUCTION The prevalence of frontal fibrosing alopecia (FFA) is increasing worldwide, though the pathogenesis remains unknown. Anecdotal reports describe alopecia occurring in an FFA pattern following facial surgical procedures, but this potential link remains unexplored. OBJECTIVE The objective of this study is to determine if a significant association exists between the diagnosis of FFA and a history of facial and scalp surgical procedures. METHODS This retrospective study comparing data from frontal alopecia patients to controls was conducted at a tertiary medical center. Additionally, a literature review was conducted on scarring alopecias occurring from scalp procedures. RESULTS Fifty percent of frontal alopecia patients (n = 54) reported a history of facial surgical procedures compared to 9.8% of controls (n = 51) (OR: 7.8 [95% CI: 2.77-25.98, p < 0.001]). Although no significant differences were observed in current daily facial sunscreen use, sunscreen use prior to alopecia onset was significantly higher in frontal alopecia (p = 0.295; p = 0.021). Sunscreen use was not a significant modifier in the association between frontal alopecia and facial surgical procedures (p = 0.89). CONCLUSIONS A significant association exists between frontal alopecia clinically consistent with FFA and a history of facial surgery, the nature of which is unclear. The role of sunscreen use and frontal alopecia development in this setting needs to be better elucidated.

Abstract
With great interest we read the recently published article by Joos et al.1 on the successful use of baricitinib for cutaneous lupus erythematosus (CLE). The authors present a heavily pre-treated case (including current systemic standard CLE medication such as hydroxychloroquine, topical and systemic corticosteroids) of subacute cutaneous lupus erythematosus (SCLE) that almost completely cleared (decline of CLASI score from 21 to 3) following 6 months of baricitinib therapy. We would like to add our experiences of baricitinib for SCLE in a patient with concomitant frontal fibrosing alopecia (FFA).

Abstract
BACKGROUND Lack of validated and responsive outcome measures in the management of Frontal Fibrosing Alopecia (FFA) significantly limits our ability to assess disease progression and treatment response over time. OBJECTIVES The aim of this study was to understand how FFA extent and progression is currently assessed in UK specialist centres, validate components of the International FFA Cooperative Group (IFFACG) statement on FFA assessment, and identify pragmatic advice to improve FFA management in clinic. METHODS Consultant Dermatologists with a specialist interest in hair loss (n=17) were invited to take part. Preferred FFA assessment methods were explored using questionnaires and clinical scenarios. Participants were asked to identify and mark the current hairline in 10 frontal and 10 temporal hairline images, with assessment repeated 3 months later (to assess intra-individual variability) and 12 months later (to test whether inter-individual accuracy could be improved with simple instruction). RESULTS All 17 clinicians (100%) completed the questionnaire at each time interval. We identified a wide variation in assessment techniques between our experts. Measurements were perceived as the most accurate method of assessing frontal recession whereas photography was preferred for temporal recession. Inter-rater reliability between clinicians measuring the frontal hairline scenarios indicated a moderate strength of agreement (ICC 0.613; 95% CI: 0.398 to 0.848), yet intra-rater reliability was found to be poor with wide limits of agreement (-8.71mm to 9.92mm) on follow-up. Importantly, when clear guidance was provided on how the hairline should be identified (questionnaire 3), inter-rater reliability improved significantly, with an ICC 0.702 suggesting moderate agreement (95% CI: 0.508 to 0.890; p<0.001). A similar pattern was seen with temporal hairline measurements, which again improved in accuracy with instruction. CONCLUSION We show that accuracy of measurements in FFA can be improved with simple instruction and validate components of the IFFACG measurement recommendations.

Abstract
INTRODUCTION Hair disorders are one of the most common conditions within dermatology practice but, although new diagnostic tools and therapeutic options have arisen, the management of these patients still represents a major clinical challenge. OBJECTIVE This study aimed at gathering information and achieving consensus on relevant recommendations on the latest advances in alopecia, trichoscopy and hair dermocosmetics. METHODS Experts of the steering committee consulted the available evidence on trichology-related areas from the past 5 years and formulated recommendations based on the evidence and their experience. A modified two-round Delphi procedure was performed among 45 European dermatologists experts in trichology to consult their degree of agreement on twenty recommendations, using a 4-point Likert scale. Consensus was defined as >80% of participants scoring either 1 (totally agree) or 2 (agree). RESULTS In the first round of the Delphi questionnaire, 75% of the recommendations reached consensus. Those that were not agreed upon were reformulated by the steering committee and voted again after an online meeting, where consensus was achieved in all recommendations. CONCLUSIONS All recommendations reached consensus after the two-round Delphi questionnaire and may be useful in clinical practice for dermatologists. The participants agreed that besides this consensus, further clinical studies are needed to assess the benefits of the emerging tools and treatments and to clarify the controversies that still exist in the field, aiming at improving patients' quality of life.

Abstract
Lichen planopilaris is a primary lymphocytic cicatricial alopecia that commonly presents with hair loss at the vertex or parietal scalp. Patients may also have associated scalp itching, burning or tenderness. Due to scarring, hair loss is typically permanent. The main goals of treatment are reducing symptoms and preventing disease progression and further hair loss. Currently, the literature has limited evidence on treatments for this difficult condition, and most available evidence is from case reports and case series. Furthermore, the evidence shows a varied response to therapy, with frequent reports of poor response. This article reviews the diagnosis of this rare disease, summarize the currently available treatments, and provide insights and practices from alopecia experts.

Abstract
The increasing incidence of frontal fibrosing alopecia (FFA) suggests that environmental factors may be related to the pathogenesis. Recent studies reported potential association between the use of facial care products and FFA. The aim of this study was to investigate the possible association between the use of facial care products and FFA in Asian females. A total of 250 females (50 FFA patients, 100 pattern hair loss [PHL] patients, and 100 normal controls) were recruited and completed a questionnaire to obtain information approximately facial care products and various environmental factors. Our study revealed the use of moisturizer to be significantly higher in the FFA group compared to normal controls (p < 0.001), and sunscreen use was significantly higher in the PHL group than in the control group (adjusted p < 0.001). Subjects with FFA or PHL reported significantly higher use of both sunscreen and moisturizer compared to normal controls (p < 0.001). This study focused on Asian populations. Our results revealed a high frequency of moisturizer and sunscreen use in both FFA and PHL among Asian females. Therefore, the use of facial care products appears not to be linked to the true disease mechanism of FFA, but rather to appearance-related concerns of patients.

Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) has become one of the most common causes of cicatricial alopecia worldwide. However, there is a lack of clear aetiology and robust clinical trial evidence for the efficacy and safety of agents currently used for treatment. OBJECTIVES To enable data to be collected worldwide on FFA using common criteria and assessment methods. METHODS A multicentre, international group of experts in hair loss was convened by email to create consensus recommendations for clinical trials. Consensus was defined at > 90% agreement on each recommended part of these guidelines. RESULTS Standardized diagnostic criteria, severity rating, staging, and investigator and patient assessment of scalp hair loss and other clinical features of FFA were created. CONCLUSIONS These guidelines should allow the collection of reliable aggregate data on FFA and advance efforts in both clinical and basic research to close knowledge gaps in this condition.

Abstract
Frontal fibrosing alopecia (FFA) is an acquired primary lymphocytic cicatricial alopecia characterized by frontotemporal hairline recession, leading to scarring alopecia with a band-like distribution. Prevalence is increasing worldwide, being the most frequent cause of primary scarring alopecia. The natural history of this condition is variable; however, slow progression with spontaneous remission is the most frequent reported outcome. The etiopathogenesis of FFA remains to be elucidated; numerous hypotheses concerning hormonal effects, environmental factors, and genetic predisposition have been proposed. Special interest on genetic basis has emerged since the first familial case was reported. Only a few more familial cases have been published. We report 6 additional cases of female patients with familial FFA (F-FFA) from 3 different families. Sixty-six percent had a family history of autoimmune disease in first-degree relatives; these same patients had a personal history of autoimmune disease. The families described in this cohort study plus the personal and family history of autoimmune disease, as well as the recently described involved genomic loci; reinforced the hypothesis of this disease being genetic. It is important to consider studying this entity since there are scarce data regarding familial cases and this might give us a better insight toward understanding its pathogenesis.

Abstract
Irreversible destruction of the hair follicle (HF) in primary cicatricial alopecia and its most common variant, frontal fibrosing alopecia (FFA), results from apoptosis and pathological epithelial-mesenchymal transition (EMT) of epithelial HF stem cells (eHFSCs), in conjunction with the collapse of bulge immune privilege (IP) and interferon-gamma-mediated chronic inflammation. The scaffolding protein caveolin-1 (Cav1) is a key component of specialized cell membrane microdomains (caveolae) that regulates multiple signaling events, and even though Cav1 is most prominently expressed in the bulge area of human scalp HFs, it has not been investigated in any cicatricial alopecia context. Interestingly, in mice, Cav1 is involved in the regulation of (1) key HF IP guardians (TGF-β and α-MSH signaling), (2) IP collapse inducers/markers (IFNγ, substance P and MICA), and (3) EMT. Therefore, we hypothesize that Cav1 may be an unrecognized, important player in the pathobiology of cicatricial alopecias, and particularly, in FFA, which is currently considered as the most common type of primary lymphocytic scarring alopecia in the world. We envision that localized therapeutic inhibition of Cav1 in management of FFA (by cholesterol depleting agents, i.e., cyclodextrins/statins), could inhibit and potentially reverse bulge IP collapse and pathological EMT. Moreover, manipulation of HF Cav1 expression/localization would not only be relevant for management of cicatricial alopecia, but FFA could also serve as a model disease for elucidating the role of Cav1 in other stem cell- and/or IP collapse-related pathologies.

Abstract
Frontal fibrosing alopecia is a scarring alopecia, the prevalence of which is increasing worldwide since its first description in 1994. The reason for this emerging epidemic may be a higher exposure to an unknown trigger, although its aethiology and pathogenesis still remain enigmatic. Clinical, trichoscopic, sonographic, and histopathologic findings are allowing clinicians to understand more aspects about this type of cicatricial alopecia. Several treatments have been used in frontal fibrosing alopecia, although the 5-alpha reductase inhibitors seem to be the most promising. The aim of this report is to provide a compilation about the published data regarding frontal fibrosing alopecia in a narrative review.

Abstract
Despite their distinct clinical manifestation, frontal fibrosing alopecia (FFA) and lichen planopilaris (LPP) display similar histopathologic features. Aberrant innate immune responses to endogenous or exogenous triggers have been discussed as factors that could drive inflammatory cascades and the collapse of the stem cell niche. In this exploratory study, we investigate the bacterial composition of scalp skin and plucked hair follicles (HF) of patients with FFA, LPP and alopecia areata circumscripta (AAc), as well as healthy individuals, in relation to cellular infiltrates and the expression of defense mediators. The most abundant genus in lesional and non-lesional HFs of LPP and FFA patients was Staphylococcus, while Lawsonella dominated in healthy individuals and in AAc patients. We observed statistically significant differences in the ratio of Firmicutes to Actinobacteria between healthy scalp, lesional, and non-lesional sites of FFA and LPP patients. This marked dysbiosis in FFA and LPP in compartments close to the bulge was associated with increased HβD1 and HβD2 expression along the HFs from lesional sites, while IL-17A was increased in lesional HF from AAc patients. The data encourage further studies on how exogenous factors and molecular interactions across the HF epithelium could contribute to disease onset and propagation.

Abstract
Human skin and hair follicles are recognized sites of microbial colonization. These microbiota help regulate host immune mechanisms via an interplay between microbes and immune cells, influencing homeostasis and inflammation. Bacteria affect immune responses by controlling the local inflammatory milieu, the breakdown of which can result in chronic inflammatory disorders. Follicular microbiome shifts described in some inflammatory cutaneous diseases suggest a link between their development or perpetuation and dysbiosis. Though the hair follicle infundibulum is an area of intense immunological interactions, bulb and bulge regions represent immune-privileged niches. Immune privilege maintenance seems essential for hair growth and regeneration, as collapse and inflammation characterize inflammatory hair disorders like alopecia areata and primary cicatricial alopecia. Current research largely focuses on immunological aberrations. However, studies suggest that external stimuli and interactions across the follicular epithelium can have profound effects on the local immune system, homeostasis, and cycling. Herein, we review hair follicle bacterial colonization, its possible effects on the underlying tissue, and links to the pathogenesis of alopecia, beyond the pure investigation of specific species abundance. As skin microbiology enters the metagenomics era, multi-dimensional approaches will enable a new level of investigations on the effects of microorganisms and metabolism on host tissue.

Abstract
Cutaneous photobiology studies have focused primarily on the ultraviolet portion of the solar spectrum. Visible light (VL), which comprises 50% of the electromagnetic radiation that reaches the Earth's surface and, as discussed in Part I of this CME, has cutaneous biologic effects, such as pigment darkening and erythema. Photoprotection against VL includes avoiding the sun, seeking shade, and using photoprotective clothing. The organic and inorganic ultraviolet filters used in sunscreens do not protect against VL, only tinted sunscreens do. In the United States, these filters are regulated by the Food and Drug Administration as an over-the-counter drug and are subject to more stringent regulations than in Europe, Asia, and Australia. There are no established guidelines regarding VL photoprotection. Alternative measures to confer VL photoprotection are being explored. These novel methods include topical, oral, and subcutaneous agents. Further development should focus on better protection in the ultraviolet A1 (340-400 nm) and VL ranges while enhancing the cosmesis of the final products.

Abstract
BACKGROUND Contact sensitization is frequent among patients with frontal fibrosing alopecia (FFA) (52%-76%). OBJECTIVE To evaluate the frequency of sensitization/photosensitization in an FFA population. METHODS A population of FFA patients were patch tested (Spanish Contact Dermatitis Research Group [GEIDAC] baseline; cosmetic and fragrance series), and photopatch tested (sunscreen series). RESULTS Thirty-six patients (mean age: 64.6 years; 35/36: women) were studied. A history of dermatitis was recorded in 69.4% (frequently involving the face). Overall, 80.5% patients showed positive patch-test reactions. The most frequently positive allergens were nickel sulfate (25%), benzyl salicylate (22%), gallates (16.6%), propolis (16.6%), and limonene hydroperoxides (13.8%). Benzyl salicylate was likely relevant to the dermatitis (labeled on personal care products and most patients reporting clinical improvement with allergen avoidance). Patch tests with sunscreens showed positive reactions to 11 materials (five patients). Photopatch tests were positive in one case. CONCLUSION We speculate a possible relationship between sensitization to benzyl salicylate and FFA. Hypothetically, the most likely explanation is that sensitization to benzyl salicylate involving FFA patients is a consequence of increased exposure to it. It is unclear whether allergen avoidance may impact the prognosis of alopecia. However, it seems to significantly improve the patients´ quality of life by lessening dermatitis and pruritus.

Abstract
BACKGROUND The sonographic characteristics of frontal fibrosing alopecia have been scarcely studied. The aim of this study was to perform a colour Doppler ultrasound evaluation in frontal fibrosing alopecia. MATERIALS AND METHODS A cross-sectional study including 99 women with frontal fibrosing alopecia and 40 control subjects was performed using ultrasound equipment with a lineal 18 MHz probe. Three areas were evaluated per patient: the alopecic area (a), the hairline implantation area (b) and healthy scalp (c). The diameter (cm) and flow (m/s) of the two most significant vessels were recorded. RESULTS With regard to the hairline implantation area, patients presented higher vessel diameter (0.127 cm vs 0.103 cm, P = .03) and vessel flow (8.183 m/s vs 7.670 m/s, P = .05) than the control group. Vessel diameter was higher in the healthy scalp area in patients than in the control group (0.088 cm vs 0.078 cm, P = .03). CONCLUSION Patients presented higher vessel diameter and flow in the hairline implantation area compared to the control group.

Abstract
Hormones play a significant role in normal skin physiology and many dermatologic conditions. As contraceptives and hormonal therapies continue to advance and increase in popularity, it is important for dermatologists to understand their mechanisms and dermatologic effects given the intricate interplay between hormones and the skin. This article reviews the dermatologic effects, both adverse and beneficial, of combined oral contraceptives (COCs), hormonal intrauterine devices (IUDs), implants, injections, and vaginal rings. Overall, the literature suggests that progesterone-only methods, such as implants and hormonal IUDs, tend to trigger or worsen many conditions, including acne, hirsutism, alopecia, and even rosacea. Therefore, it is worthwhile to obtain detailed medication and contraceptive histories on patients with these conditions. There is sufficient evidence that hormonal contraceptives, particularly COCs and vaginal rings, may effectively treat acne and hirsutism. While there are less data to support the role of hormonal contraceptives in other dermatologic disorders, they demonstrate potential in improving androgenetic alopecia and hidradenitis suppurativa.

Abstract
Introduction Frontal fibrosing alopecia (FFA) is a lymphocytic primary cicatricial alopecia typically involving the frontotemporal hairline. It may be associated with the presence of facial papules (FP) that clinically appear as noninflammatory, monomorphic, white-yellowish papules. Lichen planus pigmentosus (LPPigm) is characterized by the presence of asymptomatic grayish pigmented macules, predominantly in sun-exposed and flexural areas. Case Report A 58-year-old, Caucasian, phototype III woman presented with a symmetrical, band-like, frontotemporal alopecia with regression of the hairline; bilateral eyebrow loss; diffuse, symmetrical hyperpigmentation of the face; and some asymptomatic, flesh-colored, monomorphic papules on the chin. Based on clinical, dermoscopic, and histological findings, the diagnosis of FFA associated with FP and LPPigm was established. Discussion/Conclusion The peculiarity of our report is represented by the triple association of FFA, FP, and LPPigm in a Caucasian skin type III woman, as it has been rarely reported. Clinicians should be aware of this association also in subjects with phototype ≤III, as its recognition may be useful for diagnostic and prognostic purposes: the observation of LPPigm of the face may suggest to check for early FFA, and in case of FFA associated with FP, a poorer FFA prognosis may likely be expected.

Abstract
Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia that is often considered a clinical variant of lichen planopilaris (LPP) due to their shared histopathologic features. FFA is characterized by the recession of the frontal, temporal, or frontotemporal hairline; the clinical pattern is distinct and usually includes eyebrow hair loss, as well as other associated symptoms. Pruritus, facial papules, eyelash loss, body hair involvement, and trichodynia may also occur in addition to the frontotemporal recession and eyebrow loss classically seen. Early diagnosis and prompt treatment are critical as FFA is a progressive disorder that can result in permanent hair loss. FFA is challenging as patients may not present or be recognized until the disease has progressed. Additionally, there is currently no consensus or standard treatment regimen for FFA. While many different therapies have been reported as beneficial, there are a limited number of published guidelines for the treatment of FFA. This article is a review of the literature on treatment modalities for FFA and the objective is to offer a practical guide for clinicians on the evidence-based management options currently available in the literature.

Abstract
Despite the little information about the facial papules due to Lichen planopilaris (LPP), we have many cases with facial skin roughness in which histological study has showed LPP. Additionally, in those patients treating for frontal fibrosing alopecia or scalp LPP there was no improvement in facial papules.

Abstract
BACKGROUND To report two cases of eyelash loss in Frontal Fibrosing Alopecia, providing microscopic description of the eyelashes and possible association with Demodex folliculorum. CASE PRESENTATION We present two cases of postmenopausal women diagnosed with frontal fibrosing alopecia who consulted the ophthalmology department for eyelid itching and eyelash loss. On examination, there were no signs of blepharitis, but loss of lashes was observed, and the remaining eyelashes detached easily from the eyelid. The eyelashes were examined microscopically. The bulbs were small and narrow, and the caliber of the lashes was irregular, with thinner and thicker areas. The pigment distribution was irregular; there were portions with greater or lesser accumulation. In the second case, clusters of Demodex folliculorum were observed near the eyelash root. CONCLUSION This is the first microscopic description of eyelash loss in frontal fibrosing alopecia in the published literature. We describe small, narrow bulbs, irregular caliber of the eyelashes and irregular pigment distribution. In the second case, in which we found Demodex folliculorum infestation, there was eyelash loss even though the disease was not very advanced. We suggest that there might be an association whereby Demodex infestation might accelerate autoimmune inflammation, leading to premature eyelash loss.

Abstract
Frontal fibrosing alopecia (FFA) is a patterned primary cicatricial alopecia that was first described in 1994. Once rare, the incidence of FFA has increased dramatically, representing the current most common cause of cicatricial alopecia worldwide. FFA typically begins in postmenopausal women with symmetrical, progressive recession of the frontotemporal hairline together with bilateral loss of the eyebrows. FFA has a distinctive clinical phenotype, which remains a challenge. The histology is identical to lichen planopilaris (LPP), but only a small number of patients have coincidental LPP, usually of the scalp. The vast majority of patients have no evidence of lichen planus elsewhere, and the symmetry and patterned nature of the hair loss are unusual for LPP. Familial cases of FFA are reported, and gene associations have been identified in population studies; however, the pathophysiology remains controversial. Without treatment, FFA is slowly progressive, and although many treatments have been prescribed, the response is often disappointing. We review the pathogenesis, epidemiology, clinical features, histology, and treatment of FFA.

Abstract
Frontal fibrosing alopecia (FFA) is recognized to represent a generalized process of inflammatory scarring alopecia. Apart from the classic form affecting the frontal hairline, there are a range of disease manifestations involving loss of eyebrows and of eyelashes, loss of peripheral body hair, fibrosing alopecia in a pattern distribution, facial and extrafacial skin, mucous membrane, and nail involvement. Classic linear, diffuse “zigzag”, pseudo “fringe sign”, androgenetic alopecia-like, cockade-like, ophiasis-like and incomplete patterns are distinguished. The aetiology of FFA remains obscure, but a number of pathogenetic hypotheses and treatments to halt disease progression have been proposed.

Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) is a chronic cicatricial alopecia with unknown etiology and a worldwide rising incidence. OBJECTIVE The objective of this study was to evaluate the association of FFA with demographic and exposure factors in a Brazilian multiracial population. METHODS A multicenter case-control study was conducted in 11 referral centers throughout Brazil. The study was a case-control study that prospectively recruited 902 participants (451 patients with FFA and 451 sex-matched control individuals). Study participants completed a thorough questionnaire comprising variables grouped as baseline demographics, environmental exposure, diet, hormonal factors, allergies, and hair and skin care. RESULTS When adjusted by sex, age, menopause, and skin color, FFA was associated with hair straightening with formalin (odds ratio [OR], 3.18), use of ordinary (nondermatologic) facial soap (OR, 2.09) and facial moisturizer (OR, 1.99), thyroid disorders (OR, 1.69), and rosacea (OR, 2.08). Smokers (OR, 0.33) and users of antiresidue/clarifying shampoo (OR, 0.35) presented a negative association with FFA. There was no association with the use of sunscreen. LIMITATIONS Recall bias. CONCLUSIONS The association with moisturizers, ordinary facial soap, and hair straightening with formalin and the negative association with antiresidue/clarifying shampoo reinforce the possibility of an exogenous particle triggering FFA.

Abstract
The Primary Scarring Alopecias are characterised by the irreversible destruction and fibrosis of hair follicles, leading to permanent and often disfiguring loss of hair. The pathophysiology of these diseases is not well understood. However, follicular-fibrosis and loss of the stem-cell niche appears to be a common theme. This review explores the pathogenesis of primary scarring alopecias, asking what happens to the stem cells of the hair follicle and how they may contribute to the progression of these diseases. Bulge-resident cells are lost (leading to loss of capacity for hair growth) from the follicle either by inflammatory-mediate apoptosis or through epigenetic reprogramming to assume a mesenchymal-like identity. What proportion of bulge cells is lost to which process is unknown and probably differs depending on the individual PCA and its specific inflammatory cell infiltrate. The formation of fibroblast-like cells from follicular stem cells may also mean that the cells of the bulge have a direct role in the pathogenesis. The identification of specific cells involved in the pathogenesis of these diseases could provide unique diagnostic and therapeutic opportunities to prevent disease progression by preventing EMT and specific pro-fibrotic signals.

Abstract
BACKGROUND Despite the incidence of Frontal fibrosing alopecia (FFA) has been increasing in last two decades, the pathophysiology and trigger factors of FFA have not been yet fully understood. AIMS The aim of this study was to describe epidemiology, clinical and trichoscopic features and comorbidities of FFA patients, in order to improve the understanding of this disease. PATIENTS/METHODS A retrospective, observational monocentric study was conducted from 2003 to 2019. Data concerning epidemiology (age, gender, age of menopause, and age of FFA onset), comorbidities, current therapies, localization of FFA (such as frontotemporal hairline, occipital, eyebrow, eyelash, beard, sideburns, and body hair), presence of papules and sign of Lichen planus (LP) at skin, mucosae and/or nail were collected for each patient included. RESULTS A total of 119 Caucasian, adult patients (8 men and 111 female) with FFA were enrolled in the study. Cutaneous, mucosal, or nail localization of LP were found in 16% of our subjects. Interestingly, 15 out of 119 subjects (10.61%) were affected by concomitant genital Lichen sclerosus (LS) and 5 out of these 15 patients (4.38%) presented both LS and LP in association with FFA. CONCLUSION Considering the high prevalence of LS in FFA patients in our case series, and the frequency of autoimmune comorbidities in both LS and FFA, it is possible to hypothesize an autoimmune process in both conditions. Further studies are needed for a better understanding of the nature of the association between LS and FFA.

Abstract
Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are lymphocytic, cicatricial alopecias. Clinically, LPP presents with multifocal patchy alopecia, while FFA, considered a variant of LPP, results in hairline recession. Frontal recession in FFA may progress as far as the mid-scalp and infrequently beyond. Treatment to arrest the inflammatory process can be challenging and response variable. We report a case of recalcitrant lichen planopilaris and frontal fibrosing alopecia demonstrating significant clinical improvement after four doses of the interleukin-23 monoclonal antibody tildrakizumab.
