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.
Gray hair is more noticeable in people with darker hair because it stands out, but people with naturally lighter hair are just as likely to go gray. From the time a person notices a few gray hairs, it may take more than 10 years for all of that person\'s hair to turn gray.
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. Just in case, try not to freak out your parents too much. You don\'t want to be blamed for any of their gray hairsDevelopmental Aspects of Skin & Body Membranes
