Hair color is the pigmentation of hair follicles due to two type of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person’s hair color to change, and it is possible to have hair follicles of more than one color.
GRAY HAIR color typically occurs naturally as people age. The vast majority of people with gray hair have age-related graying.
PREMATURE GRAYING OF HAIR makes a person look much older than his/her age. Premature graying of hair is a normal occurrence in people these days.
