Your hair goes through a natural cycle of dying and then being regenerated. As your hair follicles age, they produce less color.Although your genetics will determine the actual start of graying, once you’re 35 years old, your aging hair follicles are likely to produce a white or gray hair to replace the last hair that died.While some people celebrate gray hair as a sign of maturity and wisdom, many feel that they look older when their hair starts growing gray and would like the gray to go away for a more youthful appearance.
