| Clinical Pearls | Head & Shoulders Conditioner contains pyrithione zinc, an antifungal agent effective against Malassezia species. It is primarily used as an adjunctive therapy for seborrheic dermatitis and dandruff. Since it is a conditioner, it is applied after shampooing and left on for 1-2 minutes before rinsing. It may help reduce scalp inflammation and flaking, but is not a substitute for medicated shampoos. Avoid contact with eyes; if contact occurs, rinse thoroughly with water. |
