Propecia is 1 milligram of
finasteride (
Proscar, used for prostate problems) is 5 milligrams of the same drug. Propecia is quite effective at holding on to what you've got. It sometimes gros some hair too, but I wouldn't count on it. Minoxidil works primarily on the crown of the scalp, not the front, which is the part that concerns most people. Also, over the long term, patients tend to find taking a pill a day easier than applying a lotion twice a day.
Best.
