The color of black hair mainly depends on the melanocytes at the root of the hair. As we age, the pigment cells at the root of the hair follicles will gradually stop producing melanin, which is why gray hair is formed. Although forcibly plucking gray hair does not make it grow more and more, it can damage the hair roots, especially if you pull it out too much, it may also cause folliculitis.

Gray hair refers to the graying of all or part of the hair, which can be divided into two types, one is congenital and the other is acquired. Gray hair caused by congenital inheritance is difficult to treat, but the gray hair produced by acquired causes can be improved after **.
