What causes the variety we observe in hair color? The World Book Encyclopedia explains: “The color of hair is determined largely by the amount and distribution of a brown-black pigment called melanin.” Melanin is a biological pigment that is found in hair, skin, and eyes. The greater the amount of the pigment, the darker the hair will be. As the amount of melanin lessens, the hair color varies from black to brown or rust or blond. If hair contains no melanin at all, it looks shiny white.
