Treatment for mild scalp psoriasis that has persisted for a long time typically involves medicated lotions or shampoos instead of tablets. To lessen scaling and itching, doctors frequently recommend short-term steroid scalp treatments like Clobetasol Propionate in addition to keratolytic shampoos that contain coal tar or salicylic acid. Keep the scalp hydrated, use them frequently as directed, and refrain from itching. A dermatologist can modify treatment or recommend more potent choices if patches spread or don't get better.
