Tea tree oil
A randomised four-week trial found a 5% tea tree oil shampoo significantly improved dandruff severity versus placebo, with good tolerance. Here tea tree supplies the clarifying, anti-microbial note within a physical scrub; this product is not a 5% leave-on treatment, and a sensitive scalp should use it sparingly.
