What causes white hair?

lack of sleep and thinking too much i heard

 

doesn't matter, having a few strand of white hair won't kill you, just color it

i would only worry if i was growing bald!!

 

grey hair ain't got nothing to do with stress, i did some research on the net. i'm 20 and i have more grey hair than my mother!!! =( i'm so scared that one day my whole head will be all grey. my mum and dad only have about 10 grey hair on their head but its okay cause they're like 40 50's but me, im sooo young to get it waaaaaaa. who gene's is it?

 

stress and lack of protein(??)
i was getting my hair done for prom, and the hairstylist said i need to eat more beef because i had a lot of white strands.

 

i think shd be lack of sleep, over-stressed,picky with food or some problem related to the genes

 

white hair people are more wise like those old ancient chinese dude

 

i was just playing with my mummy's hair the other day and two white ones came out... one was like half white ish. i wonder if its just the color cells start to die?

 

It is most likely to be stress, pressure.

 

yea...

Some are just natural too

 

i agree with all of the above; namely stress beside the age factor is what makes hair white. or it could be genetics but that's very rare. i have a friend who has some white strands of hair (even from the root) who's had it ever since she was little so it's in her DNA.

 

sigh, i got mine from genes, stress also maybe, im unsure, i hate it is so visible i have to dye my hair every month

 

I believe stress casuing white hair

 

I think it is due to a lot of stress well a lot of young people have it.

 

how to change get white hair to change back to black hair? without dyeing it with hair color??

 

I think white hair is part of aging, it also runs in the genes and stress is also a factor...As for what to eat to have less white hair...I heard u can eat "fat choi" although I would love to find out more recipes if anyone knows anything...white hair is annoying to have I heard the more you dye your hair, the more white hair u get~

 

i agree.

 

you say that white hair is annoying but its weird to think that there are people out there who like to have white hair, otherwise why whould there be an option to highlight your hair white. lol

 

I would say some gene and some because of stress.
My mom she stress unnecessarily a lot, she is 65 but no white hair.

 

genese, diet, and environment.

many of my friends have white hair at an early age, in their teens. im thankful i dont have any at all, not even 1 i dont think. but i believe my diet plays a role. i eat almost anything, and etc.
