Been on finasteride for 6 years - will it continue to work for many more years?

It works by reducing the amount of dihydrotestosterone (DHT) in the scalp, which is a hormone that can cause hair follicles to shrink and eventually stop producing hair.

The effectiveness of finasteride can vary from person to person, and some men may experience a slowing or even reversal of hair loss while others may not see any improvement. However, if you have been taking finasteride for 6 years and have been seeing positive results, it is likely that it will continue to be effective for you in the future.

...If you stop taking the medication, any hair that you have gained may be lost and your hair loss may resume.

It is also important to discuss any concerns or questions you have about finasteride with your healthcare provider, as they can provide personalized advice and guidance based on your individual health history and circumstances.
