Over the entire period they pass several stages, the duration of each is from 2 to 5 years: growth (anagen), rest (catagen), prolapse (telogen). Each of the hairs lives in its own mode, so at the same time they are at different stages of the cycle. Usually grows about 80%, the rest are in the stage of rest and loss, thereby freeing up space for new hair. The growth time is calculated per day. And the speed depends on many reasons. It is known that in the dark the hair does not grow. And in summer and spring grow faster than in winter. The growth rate is 0.35 mm per day. Approximately 10 mm of hair can grow in a month. As experts say, for some people, for various reasons, hair can grow by 1.5-2 cm in one month. Given how much hair on the head of a person, it is found that many "sleeping" follicles are hidden in the skin. Of these, strong healthy hair can grow.
