That explains everything, dutasteride is purposely made to shrink the prostrate in cancer patients, low dose finasteride is for treating hair loss and the high dose finasteride is sometimes used to shrink an enlarged prostate, n sometimes mixed with another alpha blocker for prostate cancer treatment, but 9 times out of 10 doctors will prescribe dutasteride to shrink the prostate.
we really only need a low dose finasteride to take care of DHT and treat or prevent a receding hairline.
