In studies, Enstilar Foam (calcipotriene / betamethasone dipropionate) has been used safely and effectively to treat plaque psoriasis on the body and scalp in adults and adolescents ages 12 to 17 years of age. Foam preparations are often preferred by patients with scalp psoriasis (over ointments or thick creams) and the ingredients in Enstilar Foam are considered standard first-line treatments.
