A Cohort Clinical Study on the Ef…atitis of the Scalp.

In a 4-week trial, piroctone olamine combined with salicylic acid significantly reduced dandruff (55% improvement), itching (53% improvement), and scalp redness in 20 people with moderate to severe seborrheic dermatitis. After 16 weeks of maintenance treatment, 90% of participants saw their condition improve to mild, with only 2 experiencing temporary recurrence.
