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 Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research On Pathways for Small Molecules Into and Out of Human Hair Fibers
Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.
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.

Unpigmented keratinocytes absorb substances faster, while melanocytes bind more strongly to melanin.
research Hair melanocytes as neuro-endocrine sensors—Pigments for our imagination
Hair melanocytes help the skin respond to stress and regulate hair pigmentation.
research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Photochemical alterations in human hair. I. Artificial irradiation and investigations of hair proteins
Melanin in black hair protects it from sun damage better than light-brown hair.
research Exosomal miR ‐199a‐3p From Dermal Papilla Cells Regulates Hair Follicle Pigmentation by Targeting POU2F1 in Melanocytes
Exosomal miR-199a-3p from dermal papilla cells helps control hair color by affecting melanocytes.
research Chemically Induced Depigmentation of Skin and Hair
Some chemicals can permanently or temporarily remove color from skin and hair, which can be distressing and is not well-regulated in cosmetics.
research High spatial resolution study of human skin using synchrotron infrared microscopy: application to the penetration of external agents
External agents penetrate skin more easily in areas with fewer lipids, especially through hair follicles.
