I've read that the active ingredient, 1% ketoconazole, in Nizoral shampoo can cause liver damage and reduce testosterone levels. So, is Nizoral shampoo safe for long term use?
I'd like to use it to help regrow my hair, instead of minozidil, because minoxidil gets absorbed through my skin too easily, causing rapid heart beat.
