I wash my hair 3 times a week twice with Nizoral 2% but when I shampoo on the third time my scalp becomes itchy and flaky using a shampoo other than Nizoral. I've used Nisim then I switched to Nioxin but after using them my scalp is flaky and itchy. I don't want to use Nizoral three times a week but read in the forum that Selsun Blue shampoo is a good shampoo for dry and flaky scalp. Any Selsun Blue shampoo users out there your input would be appreciated.
