the only time I know of that anyones hair turned gray from trauma is in cartoons like popeye and tweety and sylvester and power puff girls shows.

one time in school we had to decide if stress made hair turn gray by talking to people in our town and call some doctors. most of the class results was gray hair is caused by heridity the same as why some people had blue eyes and some had brown and some had gray or hazel. our looks are determined by our genes. if we have parents with gray hair at a young age we would end up with gray hair if we had a grandmother who was indian and had her black hair all her life we would have black hair most if not all our life. one doctor came in to the class and did this huge diagram on blue eyed mother with brown eyed dad and what kinds of eyes the kids will have from inheriting then did a diagram about black, brown, blond people and what kind of hair their kids will have and when they will go gray because of when their parents went gray.he said stress and trauma unlike the cartoons has nothing to do with turning gray so the kids who hit their heads on the playgrounds, or got a swat to the head or caused their parents to worry can relax. it made for a great class.

you can ask your doctor where gray hair comes from and they can explain the dynamics behind getting genes from your parents. maybe they will even draw you one of those fancy charts the doctor who came in to our class did. it was really cool.
