Seborrhoeic dermatitis is a skin disorder affecting the scalp, face and trunk causing scaly, flaky, itchy, red skin. It particularly affects the sebum-gland rich areas of skin. It is thought to be caused by a fungal infection caused by the yeast, Pityrosporum ovale in individuals with decreased immunity and increased sebum production.
The recommended treatment is ketoconazole creams and/or shampoos. Topical steroids should be reserved for acute flare-ups only as they make precipitate recurrences and dependence. Shampoos containing zinc, or selenium may also help.
