According to statistics, 25% of men show signs of androgenetic alopecia (also known as seborrheic alopecia) before the age of 30, and by the age of 50, more than 50% of men have lost their hair as a result. Why do men lose their hair? In the human scalp, there are about 100,000 to 150,000 hair follicles, as we grow older, the scalp area increases, the density of hair follicles from 500 to 700 per square centimeter at birth to 250 to 350 as adults. Hair growth is cyclical and is divided into anagen, regression and resting phases. In the anagen phase hair grows about 1 cm a month on average, so that a final hair of more than one meter can be grown after a few years, after which it enters the degenerative phase. The hair follicles in the degenerative phase start to degenerate and become smaller and move upward, and the hair growth function gradually decreases, and after 2 to 3 weeks, they enter the resting phase. After 2 to 3 months of rest, the hair roots gradually detach from the bottom of the hair follicle and eventually fall out when combing or washing the hair. After the resting period, new hair follicles are created, and so on and so forth, and a hair follicle grows an average of 15 to 20 hairs during a person’s lifetime. Until the follicle shrinks completely, no more hair grows. Since the growth cycle of each hair follicle is not synchronized, it is normal for us to lose about 100 hairs every day, while at the same time, an almost equal amount of new hair grows out. When a man increases the amount of an androgen called dihydrotestosterone in his scalp for some reason, and the affinity of dihydrotestosterone for androgen receptors is five times greater than that for testosterone, when it enters the nucleus, it can control the hair growth genes, making the hair follicles smaller, hair thinning and causing hair loss, and androgenetic alopecia occurs. What drugs can prevent androgenetic alopecia? There is now a topical drug with the ingredient minoxidil that can prolong the anagen phase of hair, increase the development of hair follicles in the progressive phase, and increase the vitality of hair follicles, thus playing a role in the treatment of hair loss. Another oral drug called finasteride can quickly reduce serum and scalp dihydrotestosterone levels, so it also has a significant hair growth effect.
