Alice,
What are the reasons for getting white hair in teenagers?
—Graying prematurely
Dear Graying prematurely,
Nothing turns hair white but the gradual decrease of pigmentation that occurs with age. Contrary to what you may have heard, special diets, nutritional supplements, certain vitamins, and protein will not affect the graying process. Graying, whether it comes with the normal process of aging or prematurely, has a genetic basis. Hair turns gray or white when a pigment (melanin) ceases to be produced in the hair root, and new hairs grow in gray or white. If you're a smoker, take note: a 1996 British Medical Journal study conducted by J.G. Mosley, MD found that smoking may cause premature graying. When compared to nonsmokers in the study, smokers were at a four times higher risk of graying prematurely.
Although graying usually starts in the thirty-something age range, there's nothing to worry about in graying prematurely — some say it's rather sophisticated and sexy!
