seboreayhtymiin

Seboreayhtymiin, more commonly known as seborrheic dermatitis, is a chronic inflammatory skin condition. It primarily affects the scalp, face, and chest, areas rich in sebaceous glands. The exact cause is not fully understood, but it is believed to involve an overproduction of sebum, the oily substance secreted by the sebaceous glands, and an overgrowth of a common yeast called Malassezia, which normally lives on the skin.

Symptoms typically include flaky, white to yellowish scales on oily areas of the skin. On the scalp, this manifests as dandruff. On the face, it can cause redness and scaling, particularly around the eyebrows, sides of the nose, and behind the ears. In infants, it is known as cradle cap, presenting as greasy, yellowish scales on the scalp.

Seborrheic dermatitis is not contagious and is not caused by poor hygiene. While there is no cure, it can usually be effectively managed with treatment. Options include over-the-counter or prescription shampoos containing antifungal agents like ketoconazole or selenium sulfide. Medicated creams and lotions containing corticosteroids or calcineurin inhibitors can help reduce inflammation and scaling on other parts of the body. The condition often has periods of flare-ups and remission.
