Abstract
BACKGROUND The application of photodynamic therapy (PDT) is pivotal in the management of diverse dermatologic conditions. Microneedling (MN) is a minimally invasive tool that is capable of inducing transient pores on the skin to facilitate transdermal drug delivery. Several studies have reported augmentation of PDT combined with MN. This systematic review analyzes the current studies on the efficacy and safety of MN-assisted PDT for skin diseases. METHODS The literature search using the PRISMA standard was completed through PubMed, Embase, Web of Science and CENTRAL from the establishment of the databases to November 2023. Two independent researchers finished the procedure. RESULTS A total of 12 articles and 413 subjects met our study criteria. This systematic review suggests that MN-assisted PDT can decrease the incubation time required for the photosensitizer and reduce skin lesions of actinic keratosis (AK) . The common side effect is pain and no serious adverse events were reported. CONCLUSIONS MN is an effective method to increase the transdermal delivery rate of photosensitizers. For different photosensitizers and disease, MN may show different clinical effects.

Abstract
In recent times, more than 50 % of the global population is facing hair-related issues (alopecia) which is seen mostly amongst the people in the age group of 30-40 years. The conventional topical dosage forms available in the market falls short in effectively managing alopecia. Despite various advancements in topical dosage forms, it is still disposed to limited clinical application and provides poor penetration of drug molecules into the skin. The exact etiology of alopecia is still unknown and various researchers link lifestyle, hereditary, and auto immune-based events with its existence. Nanoparticulate-based delivery are hence brought in use to enhance the permeability properties of the drug. In comparison to conventional methods nanotechnology-based drug delivery system tames drug molecules to a specific site with much better efficacy. This review is engrossed in the journey and role of nano technological-based drug delivery in the management of alopecia and its clinical application.

Abstract
BACKGROUND AND OBJECTIVES Androgenetic alopecia (AGA) is one of the most common hair loss disorders. Treatment options for AGA are limited . New therapies for AGA are clinically needed. 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is widely applied in diseases involving the pilosebaceous unit. However, limited research has explored the efficacy of ALA-PDT in treating alopecia. Some studies reported hair regrowth after PDT in alopecia areata patients, but the efficacy of ALA-PDT on AGA remains unclear. The objective of this study is to evaluate the efficacy and safety of ALA-PDT for the treatment of AGA. METHODS A randomized, placebo-controlled, split-scalp clinical study was conducted. Subjects with AGA received six sessions of 5% ALA-PDT on one half of their scalp and the red-light therapy on the other half. The treatments were applied every two weeks for six sessions on each subject. RESULTS There were 7 subjects enrolled in this study. No significant difference in hair density was observed between the red-light treatment and ALA-PDT treatment. The hair density in the ALA-PDT treated half of the scalp significantly decreased 1 week after the treatment, then it increased, and no statistical difference was found at 12 weeks after the last treatment compared to the baseline. There was no significant improvement in hair growth according to a 7-point scale and the subjects' self-assessments. The main adverse effects in ALA-PDT treatment were mild edema and tolerable pain, and no adverse effect was observed in red-light treatment. CONCLUSIONS 6 sessions of 5% ALA-PDT did not increase the hair growth of AGA patients, but slightly suppressed the sebum secretion on the scalp. The adverse effects of ALA-PDT were mild, which indicated safety and tolerability of this treatment.

Abstract
Alopecia areata is a non-scarring hair loss that commonly presents on the scalp. In men, when this condition results in facial hair loss on the cheek, jaw, and neck, it is referred to as beard alopecia areata. Beard alopecia areata can be associated with autoimmune conditions, such as diabetes mellitus, thyroid disorders, and vitiligo. A 28-year-old man presented with a five-month history of facial hair loss; his condition was diagnosed as beard alopecia areata after clinical examination. Treatment with twice daily topical 0.1% triamcinolone acetonide cream led to complete regrowth of his beard hair after six months. There are several potential agents and modalities for the treatment of individuals with beard alopecia areata. Treatment options include corticosteroid therapy (intralesional or topical), immunotherapy, Janus kinase (JAK) inhibitors, lasers, photodynamic therapy, platelet-rich plasma therapy, and treatment of an underlying Helicobacter pylori infection. Laboratory evaluation, prompted by our patient’s diagnosis of beard alopecia areata, suggested incipient diabetes mellitus and nascent thyroid disease; specifically, he had elevated fasting blood glucose and elevated thyroid-stimulating hormone levels. Therefore, in patients with beard alopecia areata, laboratory evaluation for concomitant or incipient autoimmune diseases should be considered.

Abstract
Alopecia areata (AA) is a complex immune-mediated disorder, which is difficult to treat. The available treatment options seem to have limited benefit, help only some patients and have a high relapse rate. We evaluated a new therapeutic option for moderate to severe AA based on the combination of photodynamic therapy (PDT) with 5-aminolaevulinic acid (ALA) and microneedling (MN). In total, 14 patients were enrolled, and these were randomly divided into 3 groups: Group A (MN alone; n = 9), Group B (ALA-PDT alone; n = 15) and Group C (combination of MN and ALA-PDT; n = 17). All patients were treated once every 3 weeks for a total of six treatments. The best clinical outcome was achieved in Group C, with complete hair regrowth observed in three patients, and an improvement of ≥ 50% and < 50% of the treated areas obtained in seven and six patients, respectively. Our report suggests that combination of ALA-PDT with MN could be an additional therapeutic option in moderate to severe AA, as MN allows better skin penetration of ALA and subsequent indirect immunosuppression.

Abstract
BACKGROUND Alopecia areata (AA) is a common form of patchy, nonscarring hair loss. Although intralesional steroid injections are currently the mainstay procedural therapy for AA, other nonsteroid-based procedural therapies, including platelet-rich plasma (PRP), ultraviolet radiation (UVR), and laser-based modalities, are emerging as practical options. OBJECTIVE To systematically review nonsteroid-based procedural therapies for AA and recapitulate the available clinical data. MATERIALS AND METHODS A systematic review of the literature was performed searching PubMed/MEDLINE databases identifying studies investigating PRP, UVR, and laser-based modalities for AA treatment. RESULTS Literature search yielded 644 articles encompassing PRP, UVR, and laser treatment modalities for AA. Of the 644 articles, 46 met inclusion criteria. Although numerous reports demonstrate strong potential for PRP, UVR, and laser modalities in treating AA, high-quality evidence supporting their efficacy is still lacking. CONCLUSION There is an abundance of evidence for nonsteroid-based procedural therapies in the treatment of AA. Randomized control trials comparing these treatment options head-to-head should be performed to better understand the true efficacy of these treatments.

Abstract
Alopecia areata (AA) is a T-cell mediated autoimmune disorder in which inflammatory cells attack the hair follicle, resulting in round, well-circumscribed patches of noncicatricial hair loss in normal appearing skin. AA affecting the beard area is well known and is referred to as AA of the beard (BAA) or AA barbae when involvement is limited exclusively to the beard. BAA has been documented in a select number of studies. We review the literature and discuss the clinical features, epidemiology, diagnosis, and treatment of BAA. Clinical presentation of BAA can vary and manifest as single small areas of hair loss, multiple small or large simultaneous focuses, or total hair loss. Most patients are middle-aged males with focal patches of round or oval hair loss, mostly localized along the jawline. Patches are characteristically well circumscribed and smooth with white hair present at the periphery. Dermoscopic features of BAA include yellow dots, broken hair, and short vellus hairs. BAA may be associated with other autoimmune disorders, including atopic dermatitis, vitiligo, and psoriasis. Many treatment modalities are available for BAA, and selection of a therapy depends on several factors, including disease activity, extent of area affected, duration of disease, and age of the patient. Topical corticosteroids are most commonly used as initial treatment, followed by intralesional steroids. Other therapeutic modalities are discussed.

Abstract
Experimental investigations have demonstrated that photodynamic therapy (PDT) with methyl aminolevulinate (MAL) may be a useful treatment in several inflammatory skin disorders and aesthetic indications. To assess the effectiveness, tolerability and safety of off-label MAL-PDT in daily clinical practice in 20 Italian hospital centers, a retrospective observational study of medical records of patients treated for off-label inflammatory and aesthetic indications was carried out. In all patients standard treatment options had been either ineffective, unacceptably toxic, or medically contraindicated. Clinical data regarding 221 patients affected by 22 different diseases were collected. The most common off-label indication was acne vulgaris, with >75% improvement in 72.8% of patients. Other disorders of the sebaceous gland, i.e. acne rosacea, hidradenitis suppurativa and sebaceous hyperplasia, were less responsive. Alopecia areata did not show any improvement. Granuloma annulare and necrobiosis lipoidica showed marked or moderate response in the majority of treated patients. The rate of patients with complete remission was lower for inflammatory skin disorders with hyperkeratosis, i.e. psoriasis (6/17) and porokeratosis (3/16). The efficacy for lichenoid dermatoses was dependent on the clinical variant (erosive and scleroatrophic were more responsive than hypertrophic). Only 1 of 6 patients with Zoon balanitis had a marked improvement. MAL-PDT of venous leg ulcers, photo-aging and hypertrophic scars led to a marked remission in 3/5, 3/6 and 5/8 patients, respectively. The treatment had to be interrupted because of strong pain and burning in 24 patients. Long term adverse events were not registered. Most patients with marked improvement had lasting remission with overall excellent cosmetic outcomes. The present findings demonstrate a high interest in off-label uses of MAL-PDT for inflammatory skin disorders. According to the observed clinical responses, safety, and favorable cosmetic results, MAL-PDT seems to have a potential therapeutic role for the treatment of granulomatous dermal disorders and follicular inflammatory diseases whereas results in other conditions are less encouraging.

Abstract
Alopecia areata (AA) is a non-scarring autoimmune disease of the hair follicle that can present at any age. Pediatric cases are commonly seen in a dermatology clinic, and management can potentially be challenging, with a small proportion of cases experiencing a chronic relapsing course marked by distressing hair loss that can bring about significant psychosocial morbidity. We review the established treatments for pediatric alopecia areata, alongside second and third line therapies that have shown to be efficacious. We also offer a treatment algorithm as a guide to the treatment of pediatric AA.

Abstract
Many therapeutic modalities have been used to treat alopecia areata, with variable efficacy and safety profiles. Unfortunately, none of these agents is curative or preventive. Also, many of these therapeutic agents have not been subjected to randomized, controlled trials, and, except for topical immunotherapy, there are few published studies on long-term outcomes. The treatment plan is designed according to the patient's age and extent of disease. In this paper, the therapeutic agents are organized according to their efficacy and safety profiles into first-line, second-line, and third-line options.

Abstract
Androgenetic alopecia (AGA) is the most common form of hair loss in men, and female pattern hair loss (FPHL) is the most common form of hair loss in women. Traditional methods of treating hair loss have included minoxidil, finasteride, and surgical transplantation. Currently there is a myriad of new and experimental treatments. In addition, low-level light therapy (LLLT) has recently been approved by the United States Food and Drug Administration (FDA) for the treatment of hair loss. There are several theories and minimal clinical evidence of the safety and efficacy of LLLT, although most experts agree that it is safe. More in vitro studies are necessary to elucidate the mechanism and effectiveness at the cellular level, and more controlled studies are necessary to assess the role of this new treatment in the general population.

Abstract
UNLABELLED Various therapeutic agents have been described for the treatment of alopecia areata (AA), but none are curative or preventive. The aim of AA treatment is to suppress the activity of the disease. The high rate of spontaneous remission and the paucity of randomized, double-blind, placebo-controlled studies make the evidence-based assessment of these therapies difficult. The second part of this two-part series on AA discusses treatment options in detail and suggests treatment plans according to specific disease presentation. It also reviews recently reported experimental treatment options and potential directions for future disease management. LEARNING OBJECTIVES After completing this learning activity, participants should be able to compare the efficacy and safety of various treatment options, formulate a treatment plan tailored to individual patients, and recognize recently described treatments and potential therapeutic approaches.

Abstract
PURPOSE OF REVIEW Alopecia areata is one of the most frequent organ-restricted autoimmune diseases, yet its pathogenesis is still unclear. In addition, although alopecia areata often results in significant psychological distress, effective treatment is lacking. RECENT FINDINGS New potential susceptibility loci have been implicated, but the strongest evidence points to certain class II human leukocyte antigen alleles. There is new evidence for the collapse of hair follicle immune privilege as a key step in the pathogenesis of alopecia areata. There is also new basic science evidence for stress as a contributing factor in the development of alopecia areata. Few treatments for alopecia areata have been well evaluated in randomized trials. SUMMARY Although multiple potential susceptibility loci have been implicated, the genetics of alopecia areata is still unclear. The role of any potential environmental contributors is also unclear. Quality evidence for efficacy of currently used treatments for alopecia areata is lacking.

Abstract
Alopecia areata is a common condition causing nonscarring hair loss. It may be patchy, involve the entire scalp (alopecia totalis) or whole body (alopecia universalis). Patients may recover spontaneously but the disorder can follow a course of recurrent relapses or result in persistent hair loss. Alopecia areata can cause great psychological distress, and the most important aspect of management is counseling the patient about the unpredictable nature and course of the condition as well as the available effective treatments, with details of their side effects. Although many treatments have been shown to stimulate hair growth in alopecia areata, there are limited data on their long-term efficacy and impact on quality of life. We review the evidence for the following commonly used treatments: corticosteroids (topical, intralesional, and systemic), topical sensitizers (diphenylcyclopropenone), psoralen and ultraviolet A phototherapy (PUVA), minoxidil and dithranol.
