Repigmentation in vitiligo may come from melanocyte stem cells in the skin.

This article reviews various causes of hair loss linked to systemic factors, noting that careful history and examination can lead to accurate diagnosis, but reports no new clinical results.

This article discusses the cell therapy potential of follicular cell implantation for hair regeneration and reports no new clinical results, emphasizing the role of dermal papilla cells in forming new follicles.

This study found that nail abnormalities, particularly longitudinal ridging, were more frequent in vitiligo patients (78%) compared to healthy controls (55%).

This paper discusses the lack of a genetic model for androchronogenic alopecia in rodents, noting the stumptailed macaque as a better current model due to its similarities to human male-pattern baldness; it reports no new results.

Dermatologists diagnose and manage melanoma more effectively than general practitioners.

This study focused on the ultrastructural and immunohistochemical aspects of dermal mast cells in systemic mastocytosis and their interaction with the epidermal melanin unit.

This article reviews the role of trichoscopy in diagnosing hair weathering conditions like trichorrhexis nodosa and trichoptilosis and suggests treatment by avoiding harmful chemical and physical factors, but it provides no new research findings.

This review discusses the potential role of systemic corticosteroids in the treatment of progressive vitiligo, but reports no new clinical results and suggests further research is needed.

The document concludes that treatments like oral anti-androgens, minoxidil, and topical spironolactone can be effective for hair loss in men and women.

Topical spironolactone effectively treats hair loss in women.

Hair loss can cause low self-esteem, anxiety, and depression in men.

This study found that frontal fibrosing alopecia and lichen planopilaris have similar histopathological features, but FFA exhibits more prominent apoptosis and less inflammation with spared interfollicular epidermis.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

This article reviews the impact of nutritional deficiencies on hair health, detailing how they can cause structural abnormalities, pigmentation changes, or hair loss; it presents no new clinical findings.

This review discusses the complex systemic nature of vitiligo and its associations with autoimmune conditions, emphasizing the need for increased understanding and awareness of related comorbidities and psychological effects.

This article reviews the coordination of the hypothalamic-pituitary-gonadal axis, male fertility, and therapies for hypogonadism, but reports no new clinical findings.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.

This study found that while a transscrotal testosterone patch increases serum testosterone levels in hypogonadal men with AIDS and weight loss, it does not improve weight, body cell mass, or quality of life.

Vitiligo causes white skin patches and is linked to autoimmune issues.

This case report suggests that zinc supplements may be necessary to improve hair loss in hypothyroidism patients being treated with thyroxine.

This review discusses the cutaneous manifestations associated with HIV infection, highlighting that these skin conditions often present atypically and are more severe compared to those in non-HIV-infected individuals; it reports no new clinical findings.

This study concluded that microsurgical reconstruction is a reliable method to achieve stable coverage of large, complex scalp defects, although cancer control rates were poor.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

This pilot study suggests that using growth factors followed by microneedle therapy may benefit women with female pattern hair loss.

This review examines hair shaft disorders, reporting limited evidence for treatments like minoxidil and oral retinoids, and emphasizes gentle hair care and genetic counseling for managing congenital cases.
