Previously I had the problem of groin jt. Fungus. By bringing a change in diet & applying ointment on the affected surface regularly, the problem is almost solved. But now a days often I suffer from itching in the head. Though everyday twice I take bath and wash hair with water (twice in week shikakai powder wash) still the problem persists, also there is no dandruff find the scalp. Please guide with what is the cause and homoeopathic medicine to get rid of the itching.
