INTRODUCTION: Limited epidemiologic data has suggested direct associations between hair pigment, race, and incidence of alopecia areata (AA). Here, we examine the relationship between natural hair color, race, and the lifetime risk alopecia. METHODS: In this case-control study, we included UK Biobank patients of all races and self-reported hair color with diagnoses of AA, androgenetic alopecia (AGA), or scarring alopecia (SA). Multivariable logistic regression was used to detect differences in lifetime risk. RESULTS: Findings reveal a significantly increased risk of AA among individuals with black hair compared to dark brown hair (OR 1.71 [95% CI 1.22-2.38], p < 0.001). Those with red or blonde hair showed a decreased risk of AA (0.74 [0.56-0.97]; 0.62 [0.41-0.95], p < 0.05). No racial differences in AA prevalence were observed among individuals with black hair. CONCLUSIONS: Darker hair colors may be associated with a higher risk of AA, lighter hair colors with a lower risk, and differences in hair color could contribute to previously noted racial variations in AA incidence, potentially influencing dermatologists' perspectives on the disease's epidemiology.
ABSTRACT
Myasthenia gravis (MG) is an autoimmune disease that targets neuromuscular junctions. While immunotherapy remains the cornerstone of treatment, the effects of Janus kinase (JAK) inhibitors on MG remain underexplored. In this report, we describe the case of a 58-year-old woman with ocular myasthenia gravis who received treatment with the JAK inhibitor, baricitinib for alopecia areata. The patient presented with left eyelid ptosis and an inadequate response to steroids and pyridostigmine, along with symptoms of alopecia areata. Following diagnosis, we initiated a treatment regimen consisting of baricitinib for six months. After initiation of baricitinib, we observed a complete resolution of the patient's MG symptoms, accompanied by hair regrowth, even when steroids were tapered and pyridostigmine was discontinued. Furthermore, the titer of the anti-acetylcholine receptor antibody was decreased. This report represents the first reported case of anti-acetylcholine receptor antibody-positive MG that was successfully treated through the inhibition of JAK activity.
ABSTRACT
Pigmentary and hair disorders have a significant cosmetic and psychological impact. In the August issue of the Journal, we highlight the use of reflectance confocal microscopy in diagnosing and monitoring treatment responses in patients with melasma. We will also discuss new therapeutic approaches involving oral melatonin and a combination of glutathione and resveratrol for melasma. Additionally, the ongoing revolution in alopecia treatment with oral low-dose minoxidil will be spotlighted, including the circumstances under which media attention has contributed to the growing interest in oral minoxidil prescriptions.
ABSTRACT
Our study aims to synthesize existing evidence of dupilumab for alopecia areata (AA) in pediatric patients with atopic dermatitis (AD). We searched MEDLINE and Embase on March 1, 2024, using keywords related to AD, AA, dupilumab, and pediatric patient populations per PRISMA-ScR guidelines. A mean SALT score reduction of 42.6 following dupilumab treatment (p < .01) over an average of 3.21 months, and a mean reduction of Investigator Global Assessment (IGA) levels of 2.14 units (p < .01) demonstrates the efficacy of dupilumab in pediatric AA when there is concurrent AD. Our findings in combination with dupilumab's favorable safety profile in pediatric AD makes it an appealing option for AA treatment, however, a greater understanding of the underlying mechanisms, optimal pediatric patient selection criteria, long-term efficacy, and safety profile of dupilumab in this context is warranted.
ABSTRACT
Alopecia is considered a widespread yet troubling health issue, with limited treatment options. As membranous structures derived from cells carrying proteins, nucleic acids and lipids, exosomes functionally medicate intercellular communication and alter the responses of recipient cells, resulting in disease restraint or promotion. Exosomes have broad prospects in diagnosis and treatment of diseases. Studies using animal models and at the cellular level have clearly shown that exosomes from several types of cells, including dermal papilla cells and mesenchymal stem cells, have a notable capacity to promote hair growth, suggesting that exosomes may provide a new option to treat alopecia. Here, we present a thorough review of the most recent progress in the application of exosomes to hair growth.
ABSTRACT
This case series evaluated use of injectable platelet rich fibrin (termed i-PRF+) for the treatment of female pattern hair loss (FPHL). Eleven individuals underwent 3-monthly intradermal injections of i-PRF+ using a mesotherapy gun. The mean number of hair follicles containing hairs per unit area improved at 3- and 6-months follow-up (p < .001), and all participants had a negative hair pull test. Hair volume and thickness, and patient-reported outcome scores also improved at follow-up (p < .001). Adverse effects were minor and self-limited. A series of three i-PRF+ injection sessions were effective for the treatment of FPHL, as shown by improved hair analysis parameters and patient self-assessment scores.
ABSTRACT
Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia characterized by hairline recession, pruritus, and facial papules (FP). Various therapies are used to stabilize disease activity and induce remission. However, FP of FFA is resistant to treatment in many cases. In this review, we searched the PubMed and Google Scholar databases to screen the published literature on treatment options for FP in the context of FFA. Overall, 12 studies were included in this review. Available literature suggests a noticeable improvement in resistant-to-treatment FP in FFA patients with oral isotretinoin. The available evidence is limited and is derived from retrospective studies and case reports/series. Systemic isotretinoin can be considered a promising therapeutic regimen for treating resistant-to-treatment FP of FFA patients. However, more extensive, well-designed studies are necessary for confirmatory evidence.
ABSTRACT
There is increasing interest in hair loss treatment because a growing number of people affected. Nepenthes kampotiana Lecomte is known for its anticancer effects, but its potential for preventing hair loss has not been researched. Therefore, this study focused on the hair loss prevention effects of N. kampotiana Lecomte ethanol extract (Nk-EE). The results showed that Nk-EE had a proliferative effect on human follicle dermal papilla cells and inhibited cell death. In vivo experiments using androgenic areata models showed that Nk-EE had a positive effect on a variety of biomarkers such as hair-to-skin ratio, hair type frequency, and hair thickness. The results of this study suggest that Nk-EE has potential as an effective treatment for androgenic alopecia.
ABSTRACT
PURPOSE: We aim to explore a potential treatment strategy for hair loss. MATERIALS AND METHODS: A male 6-year-old child was diagnosed with hidrotic ectodermal dysplasia 2 (HED2) caused by GJB6 (p.G11R) mutations. He presented at our clinic with diffuse thinning and fine and brittle hair since birth. Additionally, the child exhibited abnormal development of teeth, fingernails, and toenails. The condition of the child's hair had not improved significantly with age. He was treated with botanical extracts combined with Minoxidil. RESULTS: After one and a half months of treatment, the patient showed remarkable hair growth. CONCLUSIONS: Our team has previously used botanical extracts in combination for the treatment of autosomal recessive wooly hair in children. In the present case, treatment with botanical extract combined with minoxidil was found to be equally efficacious. This case report provides valuable information for future studies on the use of botanical extracts in treating hair loss, as well as a safe and effective potential treatment strategy for children with congenital alopecia.

Alopecia has emerged as a global concern, extending beyond the middle-aged and elderly population and increasingly affecting younger individuals. Despite its growing prevalence, the treatment options and effective drugs for alopecia remain limited due to the incomplete understanding of its underlying mechanisms. Therefore, it is urgent to explore the pathogenesis of alopecia and discover novel and safer therapeutic agents. This review provided an overview of the prevailing clinical disorders of alopecia, and the key pathways and targets involved in hair growth process. Additionally, it discusses FDA-approved drugs and clinical candidates for the treatment of alopecia, and explores small molecule compounds with anti-alopecia potential in the drug discovery phase. These endeavors are expected to provide researchers with valuable scientific insights and practical information for anti-alopecia drug discovery.
ABSTRACT
Background: Teledermatology is the application of information and telecommunication technologies in the field of dermatology to provide remote care services based on the exchange of clinical information within a network of professionals or between professionals and patients. Tele-trichoscopy is a non-invasive, inexpensive, and easy-to-use method that applies the principle of surface microscopy at different magnifications. Alopecia areata is a non-scarring alopecia with a chronic evolution, which often needs a close follow-up. Objectives: The aim of our work was to analyze the possible benefits of telemedicine for the follow-up of patients with alopecia areata. Materials and Methods: We enrolled patients with alopecia areata, identified during the first trichological evaluation, and we divided the patients into two groups. One group was provided with the devices necessary for a telemedicine follow-up. The other group had a conventional follow-up. The total follow-up time was one year. All of the patients' photos were blindly evaluated by a team of expert dermatologists who were asked to indicate the quality of the images. The photos were also evaluated to identify disease markers. During the follow-up period, questionnaires were administered to both groups of patients to assess the quality of the visit, the level of patient satisfaction, and to identify any issues encountered by the patients. Results: There was a high degree of concordance between the images obtained by outpatient trichoscopy and those obtained by telemedicine. The satisfaction levels were the same between the patients followed via telemedicine and those seen in the outpatient clinic. Conclusions: Telemedicine applied to trichology using trichoscopy was proven to be a valid system for managing the follow-up of patients suffering from chronic recurrent scalp diseases and, above all, for maintaining continuity of care.
