This study describes androgenetic alopecia as a common non-scarring hair loss condition primarily influenced by genetic factors and androgen sensitivity, notably impacting psychosocial well-being, especially in females and younger males seeking treatment.

This comprehensive review analyzes androgenetic alopecia treatments, discussing the mechanisms, costs, efficacy, and safety of FDA-approved drugs like minoxidil and finasteride, as well as newer non-FDA-approved options that have shown effectiveness across various studies.

This article reviews the classification and treatment of cutaneous manifestations in systemic lupus erythematosus, highlighting the importance of monitoring for disease progression and reports no new clinical results.

This study reported that clascoterone cream reduced inflammatory and noninflammatory acne lesions in a trial with 1440 white males and non-pregnant females, showing it was well tolerated in these participants.

This editorial emphasizes the critical need for laser protection supervisors in the aesthetic sector due to a rise in laser-related claims attributed to inadequate training and safety protocol adherence, highlighting that better understanding and supervision can help mitigate risks.

This study found that human hair follicle cells suppress immune activity, with somatostatin playing a significant role, suggesting potential applications for treating inflammatory hair loss conditions.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This research suggests that hair keratins evolved from claw keratins in a hairless ancestor, with Hoxc13 controlling their expression in tetrapods, evidenced by the knockout of Hoxc13 hindering claw formation in Xenopus tropicalis frogs.

This article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

This study suggests that human hair follicles may actively suppress natural killer cells, which contrasts with the observed defects in NK cell regulation in alopecia areata.

This study found that Hoxc13 mutations in mice cause defects in hair, nail, and tongue structures, with the most noticeable issue being brittle hair leading to alopecia.

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This pilot study suggests injecting platelet-derived growth factors into the scalp may offer some clinical benefits for androgenetic alopecia, though further randomized trials are needed for confirmation.

This study found that local injections of interleukin-4 and neutralizing anti-interferon-γ antibody effectively treated alopecia in a mouse model, suggesting potential therapeutic pathways for human alopecia areata.

This article discusses the etiology, clinical features, and treatment of alopecia areata but presents no new clinical findings, underlining the palliative nature of current therapies.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.

This study suggests that the neuropeptide CGRP may protect against, but not restore, IFNγ-induced collapse of hair follicle immune privilege in alopecia areata.

This study reports that in primary cicatricial alopecias, increased expression of certain immune markers in the hair-follicle bulge suggests a collapse of immune privilege, which may contribute to follicle destruction.

This case report describes a serious complication of follicular unit extraction, where donor-site necrosis led to cicatricial alopecia, but was successfully treated with two-stage surgery using tissue expanders.

This study developed and validated a 50-item questionnaire, the PCOSQ-50, to effectively assess the quality of life in Iranian women with polycystic ovary syndrome, addressing aspects often missed by previous questionnaires.

This review discusses recent advances in understanding the pathogenesis of autoimmune alopecia areata and reports no new clinical results; it highlights potential for developing more effective treatments.

This article argues that human scalp hair follicles could serve as a surrogate model for studying immune privilege in the human eye, offering a novel approach for ocular IP research.

This article reviews the genetic and potential environmental factors in alopecia areata's pathogenesis and suggests a polygenic model but reports no new clinical findings.

This review discusses oxidative stress in alopecia areata pathogenesis and potential treatment strategies, reporting no new clinical results but suggesting biomarkers for oxidative stress and discussing JAK inhibitors as promising options.

This study found that immunity to self-prion peptides could be induced in Lewis rats, but in older rats, it was associated with severe skin inflammation and hair loss.

This case report describes a 29-year-old woman with longstanding alopecia areata who experienced improvement in her scalp hair loss after 7 years of topical treatment with squaric acid dibutylester.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.
