A Practical Guide to Scalp Disorders

The 2007 document reviews common scalp disorders, including dandruff, seborrheic dermatitis, tinea capitis, psoriasis, and pediculosis capitis, detailing their symptoms, causes, and treatments. It notes that nearly 50% of the population is affected by dandruff and seborrheic dermatitis, which are associated with the yeast Malassezia and treated with antifungal and other agents. Tinea capitis, prevalent in children, is treated with systemic antifungals and topical steroids. Psoriasis, affecting at least 2% of the population, is managed with topical and systemic therapies. Pediculosis capitis, common among school-aged children, is treated with insecticidal topicals and combing, plus environmental cleaning to prevent reinfestation. The document stresses the psychological impact of these conditions, the necessity of correct diagnosis, and the need for treatments that are effective and cosmetically acceptable.
