Well here is my situation, since ive been about 17-18 i noticed i had a few gray/white hairs mixed in with my brown hair. I seem to notice them more in the winter time when i lose my tan or when my hair is cut short. I am 27 now and am definatly noticing more gray hairs popping up on the top of my head. Does anyone know of anything i can do.. besides dye my hair if it gets bad, to stop the gray hair. I really dont want to go gray.
