This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review discusses diagnostic approaches for women with diffuse, nonscarring hair loss and reports no new clinical results.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review discusses the causes, clinical presentation, and management of anagen effluvium, emphasizing its psychological impact and the need for empathy and practical support, but reports no new results.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

This review discusses botulinum toxin's experimental off-label uses in dermatology, highlighting promising results but emphasizing the need for more clinical trials to confirm efficacy and safety.

This review discusses common skin appendage diseases, including their pathophysiology and treatments, but does not report new results.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This review examines complementary and alternative medicine for alopecia and finds limited support from robust clinical trials, highlighting the need for standardized studies to evaluate efficacy and safety.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This article discusses hair loss in postmenopausal women as often being multifactorial, reviewing various conditions affecting this group, but reports no new research findings.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This study found that Cacumen platycladi extract significantly promoted hair growth and reduced dihydrotestosterone levels by inhibiting 5α-reductase activity in an androgen-sensitive mouse model.

This study found that low-dose oral minoxidil 5 mg daily significantly increased hair growth in men with androgenetic alopecia over 24 weeks, with increased hair count and vertex area improvement, though most experienced hypertrichosis and some had pedal edema.

This review discusses the role of hair dyes in cosmetic dermatology, their effects on hair and scalp health, and the importance of dermatologists understanding potential side effects; it reports no new findings.

This article discusses the aging-related changes in hair structure and function, and examines various treatments like light therapy, minoxidil, and finasteride aimed at mitigating hair thinning and loss, but reports no new clinical results.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

This study concludes that phospholipid–polymer hybrid nanoparticles may be an effective delivery system for quercetin in treating androgenic alopecia by improving hair regrowth and preventing hair follicle cell apoptosis in rat models.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This review discusses common skin conditions in primary care settings and provides guidance on differential diagnoses and selecting appropriate topical treatments, but it reports no new clinical results.

This systematic review assessed cyclosporine's effectiveness with or without corticosteroids for treating alopecia areata, finding combined therapy more effective and with a lower recurrence rate than monotherapy, especially for severe cases, though results varied by alopecia type.

This review discusses the potential of evaluating hair follicle characteristics as early indicators of vascular impairment and organ damage in pre-diabetic individuals, but reports no new clinical results.

This review covers various aspects of hair biology, pigmentation, and development, focusing on genetic and biochemical modulation of hair follicle components but reports no new findings.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

This study observed that 5% minoxidil topical foam alters gene expression and signaling pathways in the scalp, providing insights into its mechanism of action in men with androgenetic alopecia.

This article presents a systematic approach for obstetricians/gynecologists to diagnose and manage common types of nonscarring hair loss in women, reporting no new clinical results.

This study found that the prevalence of androgenetic alopecia was significantly higher among smokers compared to nonsmokers, though the severity wasn't linked to smoking intensity.
