Seborrheic dermatitis is a common skin condition that primarily affects the scalp, face, and chest. It is characterized by red, flaky, and itchy skin, often with greasy scales. In infants, it is commonly known as cradle cap, presenting as yellowish, greasy scales on the scalp. In adults, it can manifest as dandruff on the scalp, or as red, inflamed patches on the eyebrows, sides of the nose, chest, and back. The exact cause is not fully understood, but it is believed to be related to an overproduction of oil by the sebaceous glands and a reaction to a yeast called Malassezia, which is normally present on the skin.

Triggers for seborrheic dermatitis can include stress, fatigue, hormonal changes, cold or dry weather, and certain medical conditions like a weakened immune system. While it is a chronic condition, symptoms can often be managed with appropriate treatment. Over-the-counter and prescription shampoos containing ingredients like selenium sulfide, ketoconazole, or salicylic acid are commonly recommended for scalp involvement. For skin lesions, medicated creams, lotions, or ointments containing corticosteroids or antifungal agents may be prescribed. Maintaining good hygiene and avoiding known triggers can also help in managing the condition. Seborrheic dermatitis is not contagious.
