Scalp psoriasis is a skin disorder that occurs on the head region and causes symptoms such as red, dry and bumpy patches as well as scaling, flaking and itching, according to WebMD. It is not an infectious condition.
Individuals who suspect they have scalp psoriasis should see a doctor for a professional diagnosis, advises WebMD. Individuals with mild cases of scalp psoriasis may not find it disruptive, but serious cases of scalp psoriasis can cause crusted sores, and the burning and itching can affect everyday life. Individuals may feel the urge to scratch frequently, which can lead to infections and hair loss.
Individuals with scalp psoriasis may use topical treatments to help alleviate the symptoms, suggests WebMD. This can include shampoos, soaps and ointments that contain ingredients such as coal tar or salicylic acid. Doctors may also use steroid injections or light therapy to treat the symptoms. Severe cases may call for stronger medications that require close medical supervision due to their ability to cause serious side effects.
There appears to be a hereditary element to psoriasis, which occurs when the immune system malfunctions and causes inflammation and an overgrowth of skin cells, states MedlinePlus. In addition to undergoing appropriate treatment, individuals can also keep the condition under control by avoiding the specific triggers that cause their flare-ups, which may include stress and alcohol.
