Does melanin affect hair color

Yes, melanin plays a crucial role in determining hair color. It is a pigment produced by melanocytes, and there are two main types: eumelanin (which can be black or brown) and pheomelanin (which is yellow or red). The type and amount of melanin present in the hair follicles dictate whether hair appears blonde, brown, black, or red. As melanin production decreases with age, hair can turn gray or white.
