every1 tell dat if u go out or when u r in d sun 4 a long time u tan i.e u become dark or black.it is true we all tan if v r in d sun. But if old ppl go out in d sun why doesnt their hair 2 become black???? y does it remain White????

Answer 1

it doesnt become black becoz of 2 reasons
1- Hair is made of dead cells. when ever a cells is inactive itis pushed to become hair like. slowly other dead cells join and they together become a strand of hair. As they r dead they remain inactive. So when ever sunlight hits it it never reacts. The skin is made of living cells thats why if v fall down and our skin tears after a few days it grows back. A certain chemical in our skin reacts with the sunlight causing it 2 get dark
2- Our skin cells contain a certain pigment that contains a chemical. When ever this chemical gets some sunlight it makes more number of pigments but slowly.
So thats y v tan

Answer 2

uv light from the sun interacts with a pigment in the skin, causing it to darken, whereas the hair does not contain the same type of pigment. In fact the sun will lighten peoples hair.
