My endo prescribed finasteride to me, which, in the 1 mg dose, is better known as Rogaine, prescribed for hair loss. The dosage prescribed for me was 5 mg, and is commonly used in treatment of growing prostate, and is known in this dosage as Proscar.
It is a commonly used antiandrogen in the US, prescribed along with spironolactone. This is the preferred antiandrogen treatment here in the US, as opposed to androcur elsewhere, because androcur was outlawed after being the subject of a "cruel and unusual punishment" lawsuit, when its most common use in America was for chemical castration of violent sex offenders in the prison system.
Anyway, the use of spironolactone in conjunction with finasteride will definitely stop hair loss. Some users have reported some regrowth, but I think that is purely anecdotal.
