Human hair pigmentation – biological aspects [PDF]
International Journal of Cosmetic Science, 2008 SynopsisSkin and hair colour contribute significantly to our overall visual appearance and to social/sexual communication. Despite their shared origins in the embryologic neural crest, the hair follicle and epidermal pigmentary units occupy distinct, although open, cutaneous compartments. They can be distinguished principally on the basis of the former’

Recent Advances in Characterization of Melanin Pigments in Biological Samples
International Journal of Molecular Sciences, 2023 The melanin pigments eumelanin (EM) and pheomelanin (PM), which are dark brown to black and yellow to reddish-brown, respectively, are widely found among vertebrates. They are produced in melanocytes in the epidermis, hair follicles, the choroid, the iris, the inner ear, and other tissues.
