The structure of human hair contains a substance that is responsible for color - melanin. With age or under the influence of some other factors (which we will mention below) the production of melanin decreases and the hair gradually begins to lose its color, turn white. The amount of this pigment in the hair follicles determines the color of the hair in general. The lighter the hair, the less melanin it contains, so light hair turns gray faster, although white hair is more noticeable on dark hair.
The process of graying hair is irreversible and cases of return to natural color are extremely rare and are exceptions.
In Eastern medicine, it was believed that sometimes white hair was due to kidney disease. Therefore, if gray hair appears too early and this is not explained by a genetic predisposition, it is advisable to consult a nephrologist.
As a last resort, you should consult a dermatologist or trichologist, who will prescribe individual treatment.
Scientists explain that gray hair is due to a natural process of discoloration. The reason for this is the high content of hydrogen peroxide (hydrogen peroxide), which oxidizes the enzymes that maintain the natural color. An international group of scientists came to this conclusion. The first connection between whitening and the level of hydrogen peroxide was discovered by the British John Wood. It is clear that the higher the content of hydrogen peroxide, the more gray hair. This discovery could lead to the emergence of means to restore the natural color of hair. But today the only way to get rid of white hair is to dye it.
