I've been using OTC Nizoral exclusively and without any conditioner for years. Shower with nizoral at night and hair wash only with nizoral in the morning. I use a shampoo scalp massage brush after I apply the nizoral. I only leave it on there for a few minutes in the shower and a few seconds during the hair wash in the morning. I apply rogaine foam afterwards. I don't believe in babying your scalp...quite the opposite. If it's going to fall, I'd rather have clean than dirty hair. My routine is not too harsh for my scalp and in fact if I use another shampoo or even nizoral with conditioner, I get bumps from the excess oil. YMMV tho.
