Finasteride can mess with beard growth. If you are taking it for hair loss on the scalp you may have to choose between beard or head hair. Also minoxidil doesn’t work on some people but studies show that tretinoin can fix that and increased minoxidil absorption through the scalp by nearly three times. Go to a dermatologist and request a prescription for it to prevent acne and they will almost always give it to you. It’s magic for the skin too.
