Exfoliative dermatitis is widespread scaling, peeling, and flaking of the skin. It is often accompanied by, itching, skin redness (erythroderma), and hair loss.
Erythroderma; Dermatitis exfoliativa; Pruritus - exfoliative dermatitis
This condition may occur in severe cases of many common skin conditions, such as eczema and psoriasis. It is sometimes caused by an allergy to drugs or another body-wide disease.
A person with severe symptoms often needs hospital care, at times in an intensive-care burn unit. This is needed in order to monitor fluid loss through the skin.
