The Dr's say I have psorisis, but it is just on my scalp. It is so itchie I can not stand it. I sometimes itch until it bleeds. It is spreading really bad. I can not wear any dark clothes or I turn it white. I seriously itch all day long. It is so embarressing. I have tried t-get, scalp oil all kinds of dandruff shampoo. My scalp is so dry and even has scale build up so the back of my head is like small speed bumbs. Does anyone have any sugestions. I need help
