Natural Hair Colors
A person's genes determine the hair/skin/eye color at birth. Hair color is determined by melanocytes cells, these cells produce and store the pigment in hair and skin. Hair color is determined by two different forms of pigment, eumelanin and pheomelanin pigments. The more eumelanin genes there are, the darker your hair will be. So, a little eumelanin and you are a blonde, a lot and you have black hair. Depending on the percentage of each pigment, the person has blonde, brown, red or black hair. As the melanocytes decay during a lifetime, the hair becomes a dull gray and later on it turns into a whitish color.
