That link explains why hair turns grey. Here is one passage:

People can get gray hair at any age. Some people go gray at a young age - as early as when they are in high school or college - whereas others may be in their 30s or 40s before they see that first gray hair. How early we get gray hair is determined by our genes. This means that most of us will start having gray hairs around the same age that our parents or grandparents first did.

Some people think that a big shock or trauma can turn a person's hair white or gray overnight, but scientists don't really believe that this happens.

It is mostly genetic BUT if you are under severe stress then it becomes conditional.
Long-term stress and health problem can cause it, but it's mostly hereditary. I started getting 'em when I was only 14!
i think its both because my mom started getting grey hair at the age of 18 because her mom started getting it around that age too so its hereditary and stress.. :))

hope I helped!
hereditary and stress. my grandmother started getting gray hair at 22. my mom got it at 30, so they think im gonna get it at 26. buuut, my sister got it earlier because she did a lot of stuff in colledge so that she could graduate 1.5 yrs early!
both. i guess dying it will be an option.
its bothh
