What is Seborrheic Dermatitis?
Seborrhoeic dermatitis is a common, chronic skin condition that causes inflammation, redness, and flaky patches on areas of the skin rich in oil glands, such as the scalp, face, chest, and upper back. It is thought to be linked to an overgrowth of yeast on the skin or an abnormal immune response to this yeast. Factors like stress, cold weather, and hormonal changes can worsen the condition.
What are the Symptoms?
Symptoms of seborrhoeic dermatitis include red, inflamed skin with greasy, yellowish scales or flakes. On the scalp, it can cause persistent dandruff or, in severe cases, thick, crusty patches. Itching and discomfort are common, and the condition may worsen during periods of stress or seasonal changes. In infants, seborrheic dermatitis is known as cradle cap and typically appears as thick, crusty patches on the scalp.
What are the Treatments?
Treatment for seborrhoeic dermatitis focuses on reducing inflammation and controlling symptoms. Over-the-counter dandruff shampoos containing ingredients like ketoconazole, selenium sulfide, or zinc pyrithione are commonly used. Prescription-strength antifungal creams, or calcineurin inhibitors may be needed for severe cases. Gentle skincare routines and avoiding harsh products can also help manage the condition.
What is the Prognosis?
The prognosis for seborrhoeic dermatitis is good, though it is a chronic condition that tends to flare up periodically. With proper treatment and maintenance, symptoms can be effectively managed, and flare-ups minimized. While the condition is not harmful or contagious, it can cause discomfort and self-consciousness, but long-term management often provides significant relief.
