How fast does human hair grow?

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.

Since the hair roots are still intact, the process of hair loss can be stopped and in some cases even reversed.
