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 study found that long-pulsed ruby laser treatment effectively reduced hair density on the beard and chest of male-to-female transsexuals, achieving a 50–90% reduction maintained over six months.

This study investigated the genetic basis of coat color variation in cattle using skin transcriptome and whole-genome analyses, identifying the ASIP gene as a significant determinant that is differentially expressed and under strong positive selection in black and brown cattle breeds.

In this study, researchers used Raman spectroscopy to identify melanin-specific features in mouse hair as potential biomarkers for gamma-radiation exposure, achieving a sensitivity of 88% and specificity of 83%, with classification accuracy declining over time beyond 7 days post-irradiation.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

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 review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

This review summarizes the biological process of melanogenesis and evaluates natural skin-whitening treatments based on their mechanisms affecting melanin production, aiming to inform on the effects and awareness of skin-bleaching creams.

This study found differences in melanin content and gene expression in skin under black and white hair of giant pandas, providing a basis for further research on hair color distribution and skin diseases.

This study reports the development of a natural hair-coloring system using size-controlled ink particles from cuttlefish ink combined with chitosan, achieving darker and more uniform black coloration on hair than existing plant-based natural colorants, without the need for metallic mordants.

This study observed that white hair can create an optical illusion of increased scalp visibility, potentially misleading clinical evaluations of hair loss and complicating hair transplantation planning, and identified five core dyeing strategies to address this phenomenon.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This article discusses the hair nutrition and growth effects of rice water and hibiscus, but reports no clinical results; it aims to understand their role in hair care.

This study found that individuals with premature hair graying had significantly lower levels of antioxidants compared to controls, but the severity of graying did not significantly correlate with oxidative stress levels.

This study found that sericin dressing containing collagen hydrolysate significantly reduced wound healing time and improved scar quality compared to commercial dressing in split-thickness skin graft donor sites.

This study found that transverse sections of scalp biopsies showing lower anagen:non-anagen hair ratios and presence of pigment casts help differentiate alopecia areata from androgenetic alopecia.

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

This study found that a dietary supplement improved hair strength and shine in participants with hair damage from breakage.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This review discusses the strengths and weaknesses of existing studies on complex dietary supplements for hair loss, emphasizing the need for valid measurement methods like TrichoScale® to quantify effectiveness; it reports no new results.

This study found that supplementing pregnant cashmere goats' diets according to nutritional standards improved their fiber production, growth, fertility, and the development of kids' secondary hair follicles.

This review discusses the potential risks associated with skin, hair, and nail supplements, highlighting concerns about safety, efficacy, and lack of regulation but reports no new clinical results.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

A balanced diet with key nutrients and possible supplements can help manage post-COVID-19 symptoms.

This article reviews potential pathomechanisms of vitiligo, emphasizing membrane alterations involving cholesterol and cardiolipin, but reports no new clinical findings.

This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.

In this study, a combined regimen of an oral supplement with Pinus pinaster, Grape seed extract, vitamins, and minerals, plus high SPF sunscreen, significantly improved mild-to-moderate facial melasma in 30 women over 84 days, reducing pigmentation and enhancing cosmetic appearance with no reported adverse effects.

This study found that the adult population in Majmaah, Saudi Arabia, has limited knowledge and practice regarding vitamin D deficiency, despite widespread awareness from media sources.

In this veterinary case report, a mixed breed dog with Malassezia dermatitis showed significant improvement and hair regrowth after 28 days of treatment with ketoconazole and other supportive therapies.
