This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

This study found that enhanced expression of the Sonic hedgehog gene via an adenovirus vector accelerated hair regrowth in mice with chemotherapy-induced alopecia.

This review discusses the mechanisms and treatment strategies for age-related hair changes, such as androgenetic alopecia and hair graying, and reports no new clinical results.

This review provides a comprehensive overview of the mechanisms, efficacy, and adverse reactions of drugs commonly used for treating benign prostatic hyperplasia but reports no new clinical results.

This review discusses the use of platelet-rich plasma for various dermatological conditions and highlights the need for more research to standardize its protocols and understand its biological mechanisms.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

In this study, oral zinc sulphate was found to cause hair hypopigmentation and significantly inhibit eumelanogenesis in mice.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

This review outlines a systematic method for diagnosing hair loss and presents no new findings; the authors emphasize the importance of biopsy in cicatricial alopecia cases.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

This study found that extracellular ATP released from UVB-irradiated keratinocytes promotes melanin production through the P2X7 receptor, indicating a role for ATP-P2X7 signaling in UV-induced melanogenesis.

This article reviews drug-induced pigmentation and reports no new clinical findings, highlighting difficulty in confirming drug associations due to factors like delayed onset and polypharmacy.

This review discusses the most popular non-surgical cosmetic procedures for men and highlights the importance of considering sex-specific factors for optimal treatment, but reports no new clinical results.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

This review discusses hormone-related hair growth, hirsutism treatment options, and the combination of eflornithine and laser hair removal, reporting no new clinical results.

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 study found that adding metformin to IPL therapy in women with PCOS significantly improved insulin sensitivity and reduced hirsutism compared to IPL therapy alone.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

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 study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

This study suggests that 3,4,5-tri-O-caffeoylquinic acid activates β-catenin to enhance pigmentation in mouse hair follicles, human melanocytes, and melanoma cells during the hair cycle's growth phase.

This article discusses treatments for male pattern baldness, noting that minoxidil is effective for improving baldness at the scalp vertex in young men, and reports no new clinical results.

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 review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study observed that the topical skin-whitening agent rhododendrol induced skin depigmentation in approximately 16,000 consumers, linked to melanocyte cytotoxicity and immune reactions.

This study found that both Japanese male and female hair darkens with age, with significant sex differences in melanin composition and melanosome morphology influencing hair color.

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.
