Is there a genetic condition that makes your natural hair color a har color that's normaly unat

Colors like blue, green, pink. Is there such a thing? I've always wondered this. Please no insulting answers.

We are born with (usually) really light hair, which keeps getting darker as we age. Hair color is determined by our DNA and does not change, unless we start losing pigment, and then what happens is we get gray hair.



Blond hair can turn greenish if you swim in a pool with too much chlorine and malnutrition can turn it reddish. There is no other change in hair color that i know of besides those and hair tint.

Not that I know of.

I don't think so the only one I can think of is colorless for albinos. Otherwise I think that the body is incapable of creating those colors at all

Well, lack of pigmentation is called albinoism. Some tree sloths have green fur, but that's due to algae colonising the hair. Sometimes after chemotherapy, the new hair growth can be a different color (usually lighter) than that before treatment, but I know of no diseases or genetic disorders which would result in blue or green hair, even pink. Hair color is determined by melanocytes in mammals. In birds, feather color is determined by refraction of light within the feather, and other pigmentation factors. Blond hair which turns green in chlorine is usuallly due to chemical reactions with bleaching agents used to make the hair blond to begin with. Severe malnutrition can result in 'red' hair in those of African descent (sort of a brick color).



So the answer is no, there are none.
