CLINICAL DIAGNOSTIC MANUAL
Scalp itching is an uncomfortable sensation that prompts the need to scratch. It can be caused by various dermatological conditions, infections, allergic reactions, or even psychological factors.
Itching may be accompanied by other symptoms such as redness, scaling, and the appearance of lesions on the scalp. Identifying the underlying cause is important for appropriate treatment.
