30-60 / 1000+ results research When The Circadian Clock Meets The Melanin Pigmentary System
Silencing certain circadian clock genes increases skin pigmentation.
research Interaction Between Stem Cell Factor and Endothelin-1: Effects on Melanogenesis in Human Skin Xenografts
SCF and ET-1 together significantly increase skin pigmentation and melanin production.
research Circulating Testosterone and Feather-Gene Expression of Receptors and Metabolic Enzymes in Relation to Melanin-Based Coloration in the Barn Owl
Barn owls with smaller black spots have higher testosterone levels, which might be due to genetic effects on hormone regulation rather than hormone effects on coloration.
research 3,4,5-Tri-O-Caffeoylquinic Acid Promoted Hair Pigmentation Through β-Catenin and Its Target Genes
A substance called TCQA could potentially darken hair by activating certain genes and increasing melanin.
research Efficacy of an Agonist of α-MSH, the Palmitoyl Tetrapeptide-20, in Hair Pigmentation
Palmitoyl tetrapeptide-20 may help reduce hair greying and increase melanin production.
research A Review of the Etiologies, Clinical Characteristics, and Treatment of Canities
Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.
research Regulatory Effects of Thai Rice By-Product Extracts from Oryza Sativa L. Cv. Bue Bang 3 CMU and Bue Bang 4 CMU on Melanin Production, Nitric Oxide Secretion, and Steroid 5α-Reductase Inhibition
BB4CMU rice bran oil may help treat hair loss and gray hair.
research A Comparative Study of Skin Transcriptomes and Histological Observations for Black and White Hair Colors of Giant Panda
The study found that giant pandas have more melanin in black hair follicles than white, with gene expression differences that could affect hair color and skin health.
research Role of Dermal Factors Involved in Regulating the Melanin and Melanogenesis of Mammalian Melanocytes in Normal and Abnormal Skin
Dermal factors are crucial in regulating melanin production in skin.
research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.
research Human Skin Color: Origin, Variation, and Significance
Human skin and hair color variation is mainly due to melanin produced by a few genes, with melanin protecting against sun damage.
research Estrogen Receptors in Black and White Hairs
Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.
research Hair Follicle Pigmentation: Mechanisms and Factors Influencing Melanin Production
Hair color is determined by melanin produced and transferred in hair follicles.
research Thyroid Hormones Directly Alter Human Hair Follicle Functions: Anagen Prolongation and Stimulation of Both Hair Matrix Keratinocyte Proliferation and Hair Pigmentation
Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.
research Aging of the Hair Follicle Pigmentation System
Hair grays due to oxidative stress and fewer functioning melanocytes.
research The Silver Locus Product (Silv/gp100/Pmel17) as a New Tool for the Analysis of Melanosome Transfer in Human Melanocyte–Keratinocyte Co-Culture
The new assay can track and measure melanosome transfer between skin cells, confirming filopodia's role in this process.
research Electron Paramagnetic Resonance Spectroscopy for Investigating Murine Telogen Skin After Spontaneous or Depilation-Induced Hair Growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research Age-Related Hair Pigment Loss
Graying hair happens due to aging and might be delayed by new treatments.
research Influence of Oxidative and Reductive Treatment on Human Hair: Analysis of Hair Damage
Chemical treatments and daily stresses damage hair, especially the cuticle layer.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research The Nutritional Biochemistry of Wool and Hair Follicles
Nutrients like vitamins, copper, zinc, and amino acids are crucial for healthy hair and wool growth.
