Hi - I'm new to this, and have recently had psoriasis diagnosed, soon to have patch tests, as it's appeared out of nowhere. I've had lots of creams so far. Betnotave, Diprobase, etc and now Diprosalic ointment. I have it on my feet and hands mostly, but there's a bit on my scalp. I see from web that there's a treatment for scalp but wondered if I could use the ointment on my scalp as I didn't get prescription for the scalp treatment. Any advice really welcome! Thanks.
