How does it work?
Male pattern hair fall is also called androgenetic alopecia. It’s related to male sex hormones, namely dihydrotestosterone (DHT). The function of DHT can be linked to helping you build muscle and maintain a healthy sex life. But DHT also affects the growth and health of hair follicles, and too much of it can make you start to lose the hair on your head as you age.
Finasteride’s mechanism of action is to partly block an enzyme called 5-A-R. This enzyme helps your body convert free or excess testosterone into DHT. This conversion of testosterone into DHT is a natural process, but not what you want if you’re losing hair.
Hair fall caused by DHT will begin affecting most men by the time they’re into their thirties. It affects up to 50% of men by the age of 50 . Finasteride lowers your levels of DHT by stopping the conversion. This helps hair growth and stops you from losing more hair.
What else does Finasteride do?
Finasteride also comes in a 5mg dose, which is used to treat benign prostatic hyperplasia (BPH). BPH is an enlarged prostate, due to hormone changes as you get older. It isn’t dangerous, but it can cause uncomfortable symptoms such as difficulty urinating.
