This study found that melanocyte progenitor cells are present in human subcutaneous adipose tissue and may differentiate into mature melanocytes, suggesting potential applications in treating skin diseases and rejuvenation.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This study reports that PDRN, commonly used for wound healing, may also have anti-melanogenesis and potential skin whitening effects in both experimental models and clinical settings.

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 sunlight exposure causes significant structural and chemical damage to hair, including cuticle loss, cortex damage, and discoloration, with water playing a major role in discoloration of brown hair.

17-β estradiol and prednisolone may speed up hair regrowth after chemotherapy.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

This study found that segmented heterochromic scalp hair associated with iron-deficiency anemia in a teenage girl completely recovered following iron supplementation, suggesting a role for iron in hair pigment production.

This study explored the potential of silk fibroin methacrylate hydrogel microneedles to deliver α-MSH directly to the epidermis in vitiligo patients, enhancing melanocyte protection and melanosome transfer, potentially offering a new treatment avenue for this challenging condition.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

This study reported that clozapine and its metabolite showed a preference for binding to pigmented hair, but were also detectable in non-pigmented hair of patients with Parkinson's, with high correlations between dose and hair concentration.

The researchers reported that hair offers a measurable protective barrier against UVB and UVA radiation, which increases with hair density, thickness, and melanin content, suggesting a role in skin cancer prevention.

Vitamin B12 deficiency can cause skin darkening and increased blood vessels, but treatment can improve symptoms.

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 demonstrated that novel curcumin analogs CMC2.24, CMC2.23, and CMC2.5 were more effective and less toxic than parent curcumin in inhibiting melanin production in normally pigmented human melanocytes, suggesting potential for skin depigmentation therapies.

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.

This study found that N-acetyl-glucosamine-loaded nanostructured lipid carriers showed promise for skin lightening in healthy volunteers by reducing melanin distribution.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

This study found that low-level laser therapy with an 830-nm wavelength most significantly stimulated hair growth in rats, compared to other wavelengths tested.

Clotrimazole, an antifungal cream, may safely reduce skin pigmentation by breaking down the enzyme needed for making melanin.

This study found that A(3)B(5) downregulates melanin production and suppresses melanoma cell growth by promoting proteasomal degradation of TRP-2.

This study observed that 5α‐dihydrotestosterone increased pigmentation in certain skin areas of male Syrian hamsters, while estradiol decreased melanocyte numbers and counteracted the androgen-induced pigmentation effects.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

This study found that differentially expressed genes in horses with white versus black coats may regulate coat color, providing insights into the genetics of skin melanin synthesis.

This study showed that knocking out the Ppp2ca gene in the epidermis of mice led to significant hair loss and disrupted hair follicle morphogenesis and regeneration.

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 observed that balding was associated with lower total body BMD in men and higher hip BMD in women, possibly due to estrogen use in the latter group.

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 article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.
