Haircolor ranges from platinum blond to ebony, due to levels of pigments produced by specialized cells called melanocytes. Those with dark hair have cells that produce a pigment called eumelanin, and those with blond or red hair have cells that produce pheomelanin. The relative ratio of eumelanin to...
