Most Helpful Girl
If you have very dark hair, and just a few grey hairs I would not be worried :) there are a lot of reasons you could begin to grow grey hair but I know a lot of times people with dark hair will have a few, and I think it is something totally normal it's just that on dark hair it shows up more than on lighter hair! I know that is the case with my boyfriend. He is only 16 but started finding a few grey hairs on his head when he was only 15, he is Hispanic though so it just shows up on his jet black hair.
Also, I think the only girls who would care would be the very shallow ones, and you probably wouldn't want them anyways :)
