scalp psoriasis

Does anyone else suffer from this? I've had it for about 20 years now. But it's just now gotten to the point where it's starting to thin my hair, and it happens to be exactly where my part is so it's very noticeable. I just got some extra strength tgel but I don't have too high of hopes for it. Does anyone have any recommendations for what they used to clear up theirs? Any help would be appreciated. I would post a picture but it's pretty embarrassing honestly.
