Seborrhoeic dermatitis affecting the scalp.
When prescribed by a doctor, this shampoo can also be used off-license to treat a skin condition called pityriasis versicolor.
How does Selsun shampoo work?
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.
Selenium also slows down the turnover of cells in the top layer of skin, which reduces flaking, scaling and itching.
Who shouldn’t use Selsun shampoo?
Children under five years of age.
People who are allergic to any ingredient of the shampoo.
