Nobody I know of in my family has brown hair. It's happened to me before. When 8 my hair turned brown from black all the previous years. Then when I was about 10 or 11 it changed to back to black. I'm 15 now and it's dark brown, and a slightly lighter brown at the tips. I've never dyed it or anything so I don't get why.
I mean I know sometimes it can be to do with exposure to the sun, but it's been cold and snowy for ages where I live. So it can't be that.
Why is it turning brown?
Do they actually matter?
