What is behind the young gray hairs?

The cards are almost always viewed as signs of age. But not always, white hair is about aging. Their hair is gray when their follicles produce less melanin, a pigment that gives hair color. Usually the first grays begin to appear after the 30s, but some women/men can see their first white hair in their 20s.

The age of the first gray age is closely linked to two major factors: race (people belonging to the Caucasian race to the precipice faster than Asians and Africans) and genetics (if your parents are gray early, not the same fate).

But if you look at your first white hair relatively early, there may be other reasons. Factors affecting their premature appearance may be smoking or even environmental pollution (the ultraviolet or air pollution).

In rare cases, premature hairs may be a sign of a disease such as vitiligo (a skin syndrome that causes the loss of pigmentation), an anemia (when the body has difficulty absorbing vitamin B12), or problems involving saliva glands or thyroids.
