Natural products might help treat hair greying.

This review discusses the role of melanocyte stem cells in skin pigmentation and potential regenerative therapies, but reports no new clinical results.

This study found that carboxytherapy significantly improved skin wrinkles, laxity, and pigmentation among 28 patients with skin aging on the abdomen, accompanied by increased epidermis and dermis thickness and no significant side effects.

This chapter details the causes and diagnostic process of pediatric alopecia, including trichoscopic findings, but reports no new clinical results.

This workshop review from the Australian Hair and Wool Research Society discusses findings in cutaneous biology and endocrinology but presents no new research results.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This review discusses the complex relationship between psychotropic medications and the skin, focusing on cutaneous side effects, dermatologic uses, and psychiatric disorders with skin manifestations, but reports no new findings.

This review details the characteristics, associations, and differential diagnoses of vitiligo and reports no new clinical findings.

This review reports the first known case of hair repigmentation associated with lamivudine use and examines mechanisms related to drug-induced hair repigmentation, suggesting potential therapeutic strategies for reversing hair graying.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

This review provides an overview of the prevalence and management of side effects of mood-stabilizing drugs in bipolar disorder patients and reports no new clinical results.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

This article reviews the pathogenesis and treatment approaches for premature graying of hair, noting the unsatisfactory options currently available, and reports no new clinical findings.

VIP reduces hair pigmentation by decreasing melanin production.

This literature review reports that mutations in the SASH1 gene are linked to different pigmentation disorders, including dyschromatosis universalis hereditaria and lentiginosis. It further suggests SASH1's significant role in melanocyte processes and its potential as a target for developing treatments for these conditions.

This review explores the shared pathogenesis of alopecia areata and vitiligo and compares treatment responses, noting that hair regrowth in alopecia areata occurs more rapidly than skin re-pigmentation in vitiligo, possibly due to differences in stem cell biology and treatment effects on melanocytes.

This study conducted in Yemen involving 50 patients found that tissue expansion was effective for correcting scars and defects from post-burn and post-war injuries, achieving a 78% satisfaction rate with minimal complications.

This study found that using ablative fractional CO₂ laser therapy combined with FUE treatment in patients with post-traumatic eyebrow scars and defects improved follicular survival rates and resulted in well-defined eyebrow shapes.

This study highlights multiple factors contributing to hair graying, such as oxidative damage, melanocyte changes, and genetic influences, and suggests that repigmentation may be temporarily reversible, offering potential targets for future treatments while urging caution when applying mouse model findings to humans.

This review discusses various aspects of hair biology and pathology, including hair growth control, hair loss causes, and scalp conditions, and reports no clinical results.

This study found that a specially designed water-in-oil microemulsion containing Panax notoginseng saponins improved hair density and other hair health indicators in mice with telogen effluvium and androgenetic alopecia, offering a promising multi-mechanism strategy for alopecia treatment with potentially fewer side effects than traditional methods.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.
