Hair color is caused by the pigments in your body. The less pigment you have the lighter your hair. Less pigment also means you will have lighter skin that is why people who have darker skin have darker natural hair usually and why people with lighter skin have lighter hair. the amount of pigment you have depends on who your parents are.
