Why gray?

When you were 30, and you noticed in his gray hairs, they do not particularly bothered. You just pulled them all. And now you look at yourself in the mirror and can not believe my eyes.

How did this happen?

At some point the body stops producing melanin, the pigment that determines the color of hair and defines who you are - red, brown, brunette or blonde. The same pigment determines the color of your skin. The more of this substance in the body, the darker skin and hair.

Each hair grows from a bulb, which is something like a tube. Hair follicles contain certain number of cells that produce melanin - melanocytes.

As we age, our body produces less and less melanin, and the hair turns gray, more and more. In the end, they become completely white, as the body completely stops the production of melanin. Become even gray hairs on the body.

Separate hair on his head sedeet not immediately. In the hair has its own life cycle. Hair grows a few years, then within a few months as it rests, and finally fall. This process occurs throughout life, whether you have gray hair or not. But when the bulb produces a new hair, it may be less melanin than before, and the hair will grow gray.

Therefore man can not turn gray overnight. Usually, the hair completely white-haired, it takes about 10 years. Although the first gray hairs can appear as early as adolescence, most of us are beginning to turn gray at 35 - 50 years. This is largely determined by heredity.

It is not clear why the body stops producing melanin. Not been proved that stress or trauma can make your hair turn white. Nevertheless, identified some factors affecting the production of melanin:

· Lack of vitamin B12 in your diet

· Thyroid disease (thyroid gland is responsible for the use of energy in the body)

· Bourneville's disease (tuberous sclerosis)

· Vitiligo (when the disease melanocytes are destroyed or missing)

Men turn gray sooner than women, and white - earlier than Asians or African Americans. Smokers turn gray before nonsmokers. First, usually turns white whiskey, then the process extends to the crown.
