The first gray hair is not necessarily a sign of old age. They can appear in young people for a variety of reasons: from hereditary predisposition to stressful situations. So is it worth worrying for those whose hair was silvered earlier than their peers?
One of the reasons for early gray hair is traditionally considered a certain genetic predisposition to this phenomenon. If your parents started turning gray when they were young, you may face the same fate. In this case, we are not talking about some kind of pathology, most likely, your body lacks the so-called melanin - the pigment that is responsible for hair color.
Graying hair before the age of 20 is sometimes caused by ailments associated with the functions of the thyroid gland. Anemia can also be the cause, as well as some autoimmune diseases. In this case, the pigment is not retained on the hair shaft, which leads to the appearance of gray hair.
It has been proven that hair color changes due to unfavorable environmental factors, exposure to radiation. In general, the condition of the hairline is associated with the health of the whole organism - if it leaves much to be desired, the vital systems wear out quickly, which leads to rapid aging.
The body of some young people is much older than their biological age. Stress accelerates all processes, therefore, early gray hair in some cases is a sign of deterioration of all systems of human life. Normally, hair should not change color until maturity, that is, up to 40-50 years.
There are cases when a quite young man became gray-haired in a matter of hours. This happens during serious shocks, for example, during a war, at a direct risk to life, etc. The exact mechanism of this graying has not yet been established. According to one of the versions, in shock situations, neuropeptides interfere with the chemical bond between protein and melanin, and the hair loses color.
Coloring is still considered the best way to get rid of gray hair. Alas, modern medicine is not yet able to stop the graying process. But careful care, the use of shampoos for your hair type will help to keep your hair healthy at any age.
