My hair is naturally changing colours. What is this called?

Question

I don't know what this is, it's not hair dye or anything I've done. My hair used to be black until I was 12ish, then it changed to a dark brown, then to a lighter brown around 15ish, now I'm starting to grow dark blonde hairs at age 18 almost 19. Does anyone know what this is called?

Answer 1

Its natural.  You'r a freak if you hair doesn't darken or lighten up as you grow up.  

It could also be too much time in the sun is bleaching it out.  Some people with dark hair will have really blonde hair at the end of the summer!  It could also be shampoos and such.  Some turn your hair dull or white-ish.

Answer 2

Most peoples hair changes colour or even goes curlier or straighter as they go through puberty and other stages of life. Just relax.

Answer 3

Your hormones/chemicals in your body are changing as you grow up...therefore changing the color of your hair.  No worries though as it is normal

Answer 4

the sun!! lol

Answer 5

Premature graying.
