Re: Itchy scalp, itchy eyes, itchy ears, etc.
That would depend on what is causing the itching. Try shampooing daily with a shampoo with zinc pyrithione in it (Head and Shoulders and generic knockoffs seem to work equally as well). If that works, then you can usually cut back after that, to once or twice a week. That seems to work for me.
