How fast does human hair grow?
Every hair has its own cycle. That is, one hair may be in the growth phase while the other is resting at the same time. This uneven cycle ensures that man always has enough hair on his head. Each hair grows 0.4 millimeters per day. With an average of 100,000 head hairs, the production rate is about 40 meters of hair per day. The individual growth period is hereditary. Therefore, hair can never become endless.
What is androgenetic alopecia in men?
Androgenetic alopecia is hypersensitive to the hormone dihydrotestosterone (DHT). This hormone is produced by the conversion of testosterone with the help of the enzyme 5-alpha-reductase. Here, the growth phase of the hair is shortened. For this reason, there is a degeneration of the hair on the head. The back of the head is usually less affected. Since the hair roots are still intact, the process of hair loss can be stopped and in some cases even reversed.

No efficacy was observed in the treatment of receding hairline or end-stage hair loss. The drug is not suitable for children and adolescents under 18 years. Women are also excluded from taking.
