i have a slight problem

[Emerald_Angel28]

A friend of mine has had problems like that since she was practically six years old. It turned one of her eyebrows and nearly her whole hair line in the front white as snow. It turned out that it's a genetic deformation. Nothing bad and it doesn't hurt or anything. It's just something hereditary that goes down from generation to generation. You should look it up.

I haven't had any grey hairs yet but a few month ago I noticed a few little wrinkles around my eyes sad I'd rather have grey hair than wrinkles. Grey or white streaks in black hair is very sexy I think xp

That has everything todo with your genetics I am afraid.
Unless you plan on dying your hair from now to hide the gray you are going to have to live with that.
And its nothing bad, just runs in the family.
