Systemic Treatments and UV Light
If you have moderate to severe psoriasis elsewhere on your body, one of these medications may help:
- Methotrexate slows an enzyme involved in the rapid growth of skin cells.
- Oral retinoids help control the growth of cells.
- Cyclosporine lowers the immune system function, and therefore helps to reduce the inflammation of psoriasis.
- Biologics target specific parts of the immune system that are overactive in psoriasis.
Talk with your doctor about the potential side effects of these treatments.
Ultraviolet (UV) light is another treatment option. Hair can block the light from reaching your scalp, so if you have thick hair, it may help to part it in rows. Hand-held devices (UV combs) can directly deliver a higher dose of light to your scalp.
What to Do for Infection
If your scalp psoriasis becomes infected, you may have crusting, tenderness, and sometimes swelling of your lymph nodes. Your doctor may prescribe an antibiotic treatment for this problem.
