Alopecia is the loss of hair, usually from the scalp, due to disease of hair follicles. Male-pattern baldness is an inherited tendency, often starting in the twenties. Alopecia areata is a disease of unknown cause producing patchy baldness, though it may be total. Prolonged fever, lupus, erythematosus, and ringworm may lead to temporary baldness, as may certain drugs and poisons.
