Anti-dandruff shampoos work because they target the real root cause - Malassezia, the fungus linked to dandruff. Ingredients like ketoconazole, zinc pyrithione, and selenium sulfide help reduce flakes, itching, and irritation by controlling fungal growth. If the problem is fungal, the treatment needs to be antifungal too. #dandruff #antidandruff #ketoconazole #scalphealth #haircare itchyscalp hairhealth
