Please could you give me some advice for a very itchy, flaky scalp. It is worse since I had chemotherapy. I wear a wig when I go out as I had a skin graft on my head for melanoma. I also have breast cancer and will soon be having radiotherapy. I have had my lymph nodes removed under my left arm and a wide local excision on my left breast. I have about a quarter to half an inch of hair now and don't wear my wig indoors as that makes it even more itchy. My scalp has never been this flaky and itchy before. Thanks Pleasant Peasant.
