Description

Selsun shampoo contains the active ingredient selenium sulfide.

Selenium sulfide kills certain types of fungi or yeasts called dermatophytes, including one called Pityrosporum (Malassezia). Overgrowth of this fungi on the skin is involved in causing seborrhoeic dermatitis, dandruff (which is a mild form of seborrhoeic dermatitis) and pityriasis versicolor. Using Seleneium shampoo reduces numbers of these fungi on the skin so helps clear up these conditions.
