DHT is a modification of the hormone testosterone in its most biologically active form. The enzyme 5-alpha-reductase is responsible for this. It triggers a chemical reaction that converts testosterone into DHT.
The effect of DHT is actually positive: it is important both for the development of the male embryo and during puberty for the transformation from boy to man. Here it ensures beard growth and general male body hair. DHT is also involved in the function of the sebaceous glands and the development of the prostate. To a development of the prostate gland involved. To a small extent, DHT is even found in women.
In the case of hereditary hair loss (androgenetic alopecia), the hair roots react hypersensitively to the metabolic product dihydrotestosterone (DHT for short), which ends the life cycle of the hair prematurely in the case of a hereditary predisposition; the hair root bends and eventually can no longer form hair. The hairs become thinner and smaller until light patches form. This is repeated again and again over time until no more hair is visible.
For this reason, there are various DHT blockers on the market that stop/delay hair loss. It is important to choose DHT blockers that are based on natural ingredients to avoid any side effects.
