Over the entire period they go through several stages, the duration of each is from 2 to 5 years: growth (anagen), rest (catagen), loss (telogen). Each of the hairs lives in “its mode”, therefore 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. Growth time is calculated per day. And the speed depends on many reasons. It is known that in the dark the hair barely grows. And in the summer and spring grow faster than in the winter. The growth rate is 0.35 mm per day. Approximately 10 mm of hair can grow in a month. According to experts, for some people, for various reasons, hair can grow by 1.5-2 cm in one month. Considering how much hair there is in a person’s head, it has been found that many “dormant” follicles are hidden in the skin. They can grow strong healthy hair. This is one of the active areas that experts are engaged in to combat baldness.
