Seborrhoeic dermatitis

This condition is distinguished by redness and patches of scale on the scalp, usually near the ears and hairline as the oil glands become sensitive to the levels of male hormones or androgens in the system. The precise cause of seborrhoeic dermatitis is unknown, although a genetic factor is almost certainly implicated. Outbreaks can be triggered by stress and can often lead to a secondary bacterial infection.
