I have seen prematurely grey hair in people even in their 20's. (My boss and my nephew). So, it is not uncommon. Check with your Dr. if you are THAT concerned, or just dye it.

Nothing is wrong with you. Some people grey earlier than others. My mom started going grey when she was 18. I probably have grey hair too, but I dye it, so I can't tell.

My son was a lot younger than you when it happened to him. There is no way to stop it but you could dye it.

I am also 24 years old and i'm getting strands of white hair on my head to. For me... I think it's caused by stress. By all of the stuff i read, it's normal and you shouldn't worry.

I know a guy who got married at your age, and even in his wedding pictures he had a full head of white hair. If you can't live with it, dye it, but it's really not that abnormal, and I, for one, think it's pretty cool.

I started getting gray hair at 15, I am now 25 years old and I can tell you that about a quarter of the hair on my head is gray. I have gray hair where a person my age shouldn't have gray hair, if you know what I mean. What I'm trying to get at is that its a perfectly normal thing. Unless you see it happening very suddenly and at a very quick speed then you shouldn't be worried. There's many reasons why people get gray, it could be stress or maybe it runs in your family. Just dye your hair if you don't like the way it looks.

I have a friend that was completely grey at your age. I think your only option is to dye it, if it bothers you.
Isn't it really weird how total grey hair ALMOST always makes a woman look older, yet, it makes a man more distinguished and mature looking. It really sucks.
