30 / 1000+ results research Human hair melanins: what we have learned and have not learned from mouse coat color pigmentation
We know a lot about mouse hair color, but not much about human hair color differences.
research Bone morphogenetic protein (BMP) signaling controls hair pigmentation by means of cross-talk with the melanocortin receptor-1 pathway
BMP signaling affects hair color by interacting with the MC-1R pathway.
research Influence of Pigmentation on the Codeine Content of Hair Fibers in Guinea Pigs
Darker hair in guinea pigs holds more codeine than lighter hair.
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 Circulating testosterone and feather-gene expression of receptors and metabolic enzymes in relation to melanin-based colouration 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 Piecing together the pigment-type switching puzzle
The document concludes that MGRN1 affects mouse fur color by interfering with a receptor's signaling, but its full role in the body is still unknown.
research Sox2 in the dermal papilla regulates hair follicle pigmentation
Sox2 controls hair color by affecting pigment production in hair follicles.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
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 Human hair melanins: what we have learned and have not learned from mouse coat color pigmentation
We know less about human hair pigmentation than mouse coat color, but pH and cysteine levels are key factors.
research Melanogenesis‐promoting effect of Cirsium japonicum flower extract in vitro and ex vivo
Cirsium japonicum flower extract increases melanin production and could help treat depigmentation conditions.

Physical exams are important in hair loss diagnosis, considering cosmetic history, systemic diseases, and classifying alopecia types.
research Transgneic Endothelin 3 Regulates Murine Pigment Production and Coat Color
The gene Endothelin 3 makes mice's fur darker by increasing pigment cells and pigment levels.
research Novel insights into hair structure and the effects of chemical stressors on hair and skin using label-free advanced light microscopy
Chemical stressors damage hair structure but the skin's outer layer protects living cells.
research The color of human hair
