I have ichthyosis (not sure what kind it is), but I am very dry (i use amlactin for my skin which i keep pretty good), but I can't use amlactin on my scalp and its very frustrating because i have very bad dandruff. I've tried all the shampoos (Nizoral, head and shoulders, selsum blue, Neutrogena t-gel), I'm kind of desperate over here!
