Treat scalp sores by applying topical medications to the areas or by taking oral medications, advises HowStuffWorks. Because there is a wide range of conditions that lead to scalp sores, you must address the underlying condition and not just the symptoms.
Ringworm, psoriasis, impetigo and pemphigus all cause scalp sores and require specific treatments. To treat ringworm, a fungal infection, keep your skin clean, wash your hair with medicated shampoos and go to a doctor for prescribed oral medication, suggests MedlinePlus.
Psoriasis is an immune system condition in which skin cells overproduce, piling up into itchy sores and scabs on the scalp, explains the National Insititute of Arthritis and Musculoskeletal and Skin Diseases. Treatments range from topical and oral medications to light treatment or phototherapy.
Another immune system disease, pemphigus foliaceus, occurs when the immune system attacks healthy skin cells and causes blisters and sores. Doctors treat it with corticosteroids to control inflammation, immunosuppressants to inhibit the immune system's attack on the cells and antibiotics to treat any secondary infections.
Although scalp sores require medical attention, take preventative measures by keeping your scalp clean and washing your hair regularly, especially after sweating, which can promote fungal growth. Avoid sharing brushes, hats and other head-related items to prevent spreading scalp infections, advises HowStuffWorks.
