This is theee ONLY thing that has helped with my seborrheic dermatitis. I have suffered for years, have tried all creams, shampoos, and have noticed stress doesn't help the issue at all. I have notice my scalp clear up like nothing before. I made a mistake and forgot to reorder and I began to itch and a flare up started. Never again. I have tried other brands on Amazon which made me very gas and uncomfortable with this brand no issues. Thank you!!!
