It just happens. In odd cases, like a person I know, she/he is not like 40 yet (where they begin to have gray or white) and she/he has already more than my mom or dad.





You can dye it back to your color.
My older brother had a little gray hair when he was 24.





My grandmother said he should eat tomatoes, and now he doesn't have gray hair any more.





This depends on your gene. But i suggest you eating more tomatoes, maybe it'll work.
It the way you born and can have gray hair in early. If you don't want to have gray hair. Just dye your hair and it will cover your gray hair.
here's an article on that http://www.webmd.com/skin-problems-and-t鈥?/a>
ageing


there is no way to prevent it from actually happen


but a very common thing is people buy this gel kinda stuff that changes hair color


they sell it at target and super clips/ great clips


its pretty common
there is no way to stop hair from turning gray, but when it appears if you don't like it then you can dye your hair to cover it up
family history of ageing and you cant prevent it
wen you get older your scalp gets week and than it becomes gray and than it falls out of your hair
genes cause it





simple, build a time machine and go back in time to change your genetics
