Patient: I am 20 y o. i had white hair at 16. is it due to masturbation? what is the cause of premature hair graying?
Doctor: Hair gets its color due to a pigment called melanin which is produced by the body. Many a times some hair can lack that pigment and thus look white. This has nothing to do with masturbation. I would not worry about one single white hair and this is deifnately not a sign of premature aging. I hope this helps.
