To treat scalp sores, you need to treat the skin condition that is causing them. In most cases, a doctor should look at the condition that's causing the scalp sores, and you'll most likely require some kind of medication, either oral, topical or both.
Treating ringworm requires taking antifungal medication for four to 12 weeks. This medication is typically accompanied by an antifungal shampoo [source: WebMD]. Impetigo is also treated with medication -- an antibiotic is necessary to kill off the bacterial infection [source: MedlinePlus].
When scalp sores are caused by a problem with the immune system, treatment can be a bit more difficult. Treating pemphigus requires taking medication either orally or via injection. You may also have to use topical creams on the sores. Medication for pemphigus can have serious side effects, so treatment needs to be monitored by your doctor. Treatment can also take a frustratingly long time -- sometimes as long as several years [source: National Institute of Arthritis and Musculoskeletal and Skin Diseases].
Psoriasis patients also need a lot of patience when going through treatment. Everyone responds to psoriasis treatments differently, so your doctor may have to try several methods before finding the one that's right for you. Usually, you'll start off with a topical treatment. If that doesn't work, your doctor will move on to something called phototherapy. Phototherapy is a process that involves exposing affected areas to certain kinds of light in order to slow cell turnover. As a last resort, your doctor will prescribe either oral or injectable medication to improve your immune system [source: National Institute of Arthritis and Musculoskeletal and Skin Diseases].
