I'm taking 1mg finasteride and using 1ml of minoxidil once a day. What happens If I stop/reduce my finasteride dosage? (Photo)

For men with male pattern balding, finasteride helps a great amount. Minoxidil helps a little bit. If you stop finasteride, you may experience hair loss. No, twice daily minoxidil does not balance the effects of oral finasteride based in all clinical studies. Yes, lower doses of finasteride (0.5 mg) may still provide some degree of help so speak to your physician about this. You might also wish to speak to your physician about off label uses of topical finasteride. 

The inhibition of the hormone that produces DHT will be reduced which will result in higher DHT levels and an increase in susceptibility of those hairs that miniaturize due to DHT to continue their progression. There will be benefit at the reduced doseage but not as effective as taking it at 1mg.  Would also recommend if you are going to continue using minoxidil, you'll need more than the suggested 1ml for it to be effective but overall minoxidil is a very effective medication.
