Some people report success on this but I have never seen any real proof or good pictures on it.
If finasteride + minoxidil is not working for you, it is possible that you are simply not a good responder to either and got the bottom of the barrel in hair genetics (which sucks big time )
If you have no side effects you might want to try it. Finasteride is safe to use up to 5mg--that's the proscar doseage.
