DHT (Dihydrotestosterone) is the main androgen responsible for promoting androgenic alopecia (male pattern baldness). Therefore, steroids that convert into DHT within the body can cause this side effect for the steroid user. However, a group of drugs called reductase inhibitors can protect the user from androgenic side effects such as steroid-induced hair loss, oily skin and acne, by reducing the amount of DHT in the body.
