Hey all. I have never used Nizoral shampoo or taken any steriods that made me worry about dht. Now taking tren a I have very concerned about hairloss and am using nizoral shampoo but my scalp is getting itchy. Is that dht buildin up and I need to shampoo more often or is it just a side of the nizoral shampoo? How often do you guys use it when trying to prevent dht that gets past my proscar?
