The document discussed how hair color is determined by the presence or absence of melanins in the hair cortex, which are produced through melanogenesis in melanosomes by melanocytes. Unlike epidermal melanocytes, hair melanocytes remain permanently active during the hair's growing phase (anagen), likely due to a specific but not fully understood regulatory network.
