We are constantly asked a lot of questions about the medicine Finasteride. Here are some of the most frequently asked questions and their answers:

Finasteride is known to work on the body’s hormones? How does that actually happen?

The male hormone testosterone is converted to its active form dihydrotestosterone (DHT) with the help of an enzyme 5-alpha reductase. This enzyme has two forms typeI and type II. Type II is present on the hair follicles and prostate gland. Finasteride inhibits thistype II 5-alpha reductase enzyme thus reducing the levels of DHT. DHT is the hormone responsible for converting the terminal hairs on scalp to fine vellus hair like that seen on the body thus leading onto baldness.

How exactly does Finasteride work?

By inhibiting 5-alpha reductase enzyme, finasteride reduces the level of dihydrotestosterone (DHT) which is responsible for baldness. When the DHT levels are lowered, there is reversal of the process of hair loss.

Who all can take Finasteride?

Clinical studies and tests have shown that Finasteride can be used to treat male pattern baldness or androgenetic alopecia. It can not only arrest hair loss, but also promote the growth of new hair. It is the only US FDA approved oral drug that is specific for treatment of male pattern baldness. It is safely advised after the age of 18 years.
