Exfoliative dermatitis is widespread scaling of the skin, often with itching (pruritus), skin redness (erythroderma), and hair loss.
Erythroderma; Dermatitis exfoliativa
It may occur in severe cases of many common skin conditions, such as eczema and psoriasis. It is sometimes caused by an allergy to drugs.
A person with erythroderma or exfoliative dermatitis often needs hospital care or admission to an intensive-care burn unit.
