Hi Thanks for your query According to your history, looks like you have seborrheic eczema.. ie dandruff over scalp associated with seborrheic lesiong over face, neck and chest. Seborrhoeic dermatitis (also known as seborrheic eczema )is an inflammatory skin disorder affecting the scalp, face, and torso. Typically, seborrheic dermatitis presents with scaly, flaky, itchy, and red skin. It particularly affects the sebaceous-gland-rich areas of skin. In adolescents and adults, seborrhoeic dermatitis usually presents as scalp scaling similar to dandruff or as mild to marked erythema of the nasolabial fold. Various topical treatments include shampoos, cleansers or creams/lotions that contain antifungal, anti-inflammatory, sebo-suppressive or keratolytic ingredients. One combination approach combines a dandruff shampoo, antifungal agent and topical steroid . Hope it helps Dr Geetika Paul
