This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This study found that finasteride decreases melanin levels in melanocyte and melanoma cells by inhibiting MC1R, without causing cytotoxicity, suggesting its potential role in regulating melanogenesis.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This study presents a computational approach, CATNIP, which repurposes drugs using only their biological and chemical information, predicting new uses like adrenergic uptake inhibitors for Parkinson's and vandetanib for Type 2 Diabetes.

This study found that overexpression of sFRP4 in skin cells reduces Wnt signaling activation, leading to decreased melanocyte differentiation in regenerating hair follicles.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This review discusses the role of skin enzymes in drug metabolism and emphasizes the need for models assessing enzyme activity to evaluate the safety and bioequivalence of topical generic drugs, highlighting efforts to standardize testing protocols for transdermal products.

This study found that rice bran ash extract enhanced melanin biosynthesis-related protein expression in a 3D hair follicle-like tissue model and hair follicle organ culture, suggesting potential for future research in melanogenesis.

This study found that treating a 3D hair dermal papilla model with rice bran extract and electromagnetic fields increased melanogenesis, suggesting potential for vitiligo and white hair therapies.

This review discusses the relationship between alopecia and psychological disorders and reports no new results.

This study found that cocaine disrupted the relationship between certain brain androgen levels and sexual behavior in male rats, with dose-dependent effects on testosterone metabolism.

This review identifies cysteine's central role in hair growth and its potential impact on Alopecia Areata's pathogenesis, suggesting examination of cysteine metabolism might clarify the disease's underlying mechanisms and lead to new treatments.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

In this case report, a 75-year-old man with benign essential blepharospasm and Parkinson disease experienced significant symptom relief from dystonia after starting finasteride, suggesting it may be a potential therapeutic option.

This chapter discusses various substances and therapies for dermatological applications, including heliotherapy, UVB, khellin, and others, but reports no new research findings.

This review discusses the mechanisms of hair repigmentation and reports no clinical results; the authors suggest further research into topical treatments for reversing gray hair.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

This study proposes a simple fluorescence method to evaluate hair damage and protection, suggesting that emissive properties of hair can aid in substantiating cosmetic claims.

This review discusses the clinical applications and adverse effects of 5-alpha reductase inhibitors for treating benign prostatic hyperplasia and androgenic alopecia, noting controversies around their implications for other diseases, without reporting new results.

In this study with C57BL/6 mice, SHJ extract was associated with increased hair growth and density, suggesting potential use in hair care cosmeceuticals, while also enhancing melanin production in melanoma cells.
