The itchy scalp

Abstract

• Scalp pruritus may be a feature of many common dermatological conditions including seborrhoeic dermatitis, psoriasis, pediculosis, eczema and lichen simplex chronicus. In some patients, androgenetic alopecia is associated with itching and irritation of the scalp. • Scalp pruritus can also be a prominent feature of contact dermatitis and rare conditions such as dermatitis herpetiformis, lichen planopilaris and trigeminal trophic syndrome. • Psychological issues, particularly anxiety, may exacerbate or manifest as scalp pruritus. • Identifying distinguishing features in the patient's history and examination to make an accurate diagnosis is important. Sometimes a therapeutic trial is required..
