In brief: Hair loss
Two types of androgens are involved in the mechanism of male pattern hair loss.
These are testosterone and dihydrotestosterone (dht). Dihydrotestosterone is a derivative of testosterone. The enzyme called 5-alpha reductase converts the relatively inactive testosterone to a more potent form, dihydrotestosterone. Thus, the key enzyme involved in androgenetic hair loss is 5-alpha reductase.
