Why do peoples hair get white or gry?

Answer 1

Hair has color when you are first born. Of course because you are just beginning to use the melanin,the thing that gives your hair it's color. Each hair has a different folicle that they grow in under the skin. Each folicle has it's own amount of melanin. When you get older, that folicle has less melanin and can't make enough to give your hair it's color. That's when your hair turns white or gray, when the hair folicle loses all or most of it's melanin.
