This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This article reviews central centrifugal cicatricial alopecia in African-descent females, discussing possible causes, associated styling habits, and potential treatments, but reports no new clinical findings; the authors call for further research.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This article discusses frontal fibrosing alopecia, noting potential connections to lichen planopilaris, but reports no new clinical findings.

In this study, tofacitinib treatment was associated with significant hair regrowth in two patients with alopecia universalis over eight months, with minimal adverse effects reported.

This review discusses androgen manipulation strategies for conditions like benign prostatic hyperplasia and prostatic carcinoma but reports no new clinical results.

This review reports that sonidegib and vismodegib, two Hedgehog inhibitors used for treating advanced basal cell carcinoma, have similar efficacy and safety profiles, but differ in pharmacokinetics, with sonidegib achieving peak concentration more rapidly and reaching steady state later than vismodegib.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This review explains the biology and preparation of platelet-rich plasma and discusses its clinical applications in plastic surgery, but reports no new findings.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

This study found that a 60-second hair count is a reliable and consistent method to assess hair shedding in healthy men without alopecia.

This study found that finasteride significantly reduced dihydrotestosterone levels but did not provide clear evidence of impaired libido or erectile function compared to placebo in men.

This study identified a novel recessive mutation in mice causing lethal congenital lamellar ichthyosis, with skin and hair follicle alterations similar to human congenital ichthyoses, linked to a specific genetic defect affecting Fatp4.

This study found that antroquinonol inhibited CD8+ T cell proliferation and reduced proinflammatory cytokine secretion in vitro, while also ameliorating H2O2-induced depigmentation and resisting reductions in hair follicle length, skin thickness, and tyrosinase expression in mice.

In this study, researchers found that the absence of P-selectin delays inflammatory cell recruitment and reepithelialization in fetal wounds, although scar formation still occurs in later gestation wounds.

This study in a Pakistani family identified a novel ST14 gene variant as the likely genetic cause of autosomal recessive ichthyosis with hypotrichosis syndrome.

This study found that hair loss is common among patients with inflammatory bowel disease, with mesalamine and anti-TNF medications associated with lower odds of experiencing hair loss.

This study evaluated potential penile vascular changes and persistent adverse effects in men discontinuing 5α-reductase inhibitors for androgenic alopecia, but no new clinical results were reported.

This article reports a rare combination of rapid-onset halo nevi, nonsegmental vitiligo, and premature scalp hair graying.

Men have worse COVID-19 outcomes than women due to genetic and hormonal differences.

This expert opinion article presents insights from dermatologists and aesthetic physicians on using polynucleotides (Rejuran®) for skin hydration, rejuvenation, structural support, barrier repair, and scar remodeling, noting their favorable safety profile but highlighting the need for more robust evidence and research.

The authors reported a case of significant scalp edema accompanying lichen planopilaris in a middle-aged woman, suggesting a potential new variant of edematous scalp conditions as a reaction to scarring alopecia.

This case report describes a 5-year-old girl with atrichia with papular lesions, whose diagnosis was confirmed through genetic testing identifying mutations in the hairless gene.

This paper reports no new results; it addresses the effects of Dutasteride on testosterone and DHT in men, and discusses the implications for androgen deprivation and COVID-19 outcomes.

Elderly patients with CCCA were all African American with low vitamin D, but no iron or zinc deficiencies, and no hormonal imbalances compared to younger patients.

This study found that a more liberal intake of restricted amino acids in patients with methylmalonic acidemia resulted in improved growth and fewer illness episodes.
