In recent years, people with hair loss have started to be older than their elders. People who started to lose hair at the age of 20 abound, and the degree of hair loss is also worse than that of their elders. According to past experience, the earlier the hair loss starts, the more severe the hair loss, which will eventually lead to the embarrassment of losing the scalp.

Therefore, in order to solve hair loss, countless people racked their brains, searched for remedies, and tasted bitter medicines, but in the end they were all useless. I think that in order to predict the final result of preventing hair loss, it is necessary to understand the process of hair growth. In order to solve the problem smoothly, let's understand the mystery of hair growth!

For humans, hair grows on the scalp, and the growth cycle of hair can be divided into degenerative period, resting period, and growth period. The length of the degenerative period and the resting period is maintained at about 1 to 3 months, and the growth period lasts about 2 to 6 years.

Calculated from the total amount, a normal human hair has about 80,000 to 150,000 hairs, of which about 80% of the hair grows normally; the rest of the hair is in the degenerative period and the resting period; the average daily growth of a hair is 0.35 mm or so; therefore, the normal amount of human hair loss should be 0-50 hairs per day, and the total number of hairs will be in a stable dynamic balance.

Secondly, the speed of hair growth is also related to time, gender, and age. Under normal circumstances, the hair grows faster in summer, and the hair of men is easier to grow than women, and the elderly are not as fast as the younger ones; These phenomena can then cause temporary hair loss. Don't worry, your hair will naturally get better after a while.

True hair loss is essentially caused by the human hair loss gene FGF-5. Under normal circumstances, it will promote hair loss when it enters the resting period. However, once the human body encounters certain inducements inside and outside the body, this gene will interfere The normal growth cycle of hair promotes the shortening of the hair cycle and early fall out. This is what we often call hair loss. In the early stage of hair loss, there are more dandruff, head oil, and thin and dry hair. In severe hair loss, there will be thinning and loss of hair. Conditions such as alopecia areata and alopecia areata.
