These pigment cells are more substantial and much more dendritic than epidermal types [31, 33]. Additionally, in epidermis Just about full transported melanin is degraded in the differentiating keratinocytes, but in hair cortical keratinocytes pigment granules are digested only somewhat [33]. Range of hair coloration occurs typically from the quantity and ratio in the brown-black eumelanin as well as the yellow-pink pheomelanin [35].
