I've been on the big 3 for about 3 months now and had great results. My question is how long should I keep using Nizoral. Is it necessary to continue indefinitely? I'm using it 3-4 times a week but I really want to cut back now that I've got some good regrwoth, the male pattern baldness "burn" is gone, I'd like to use less as it dries out my scalp and costs me money.
