Best shampoo and conditioner for psoriasis?

jessie

I have psoriasis on my head and I can’t find a shampoo that will treat it completely. I have wavy dark hair so it’s very noticeable. I’ve tried t/gel from neutrogena and Malibu scalp wellness which seem to help a little bit I don’t wash my hair everyday and it needs to be done everyday to work. Does anyone have any suggestions?
