Exams and Tests
Your doctor can often recognize psoriasis by looking at your skin, scalp, and nails.
Tests aren't usually needed. But one or more of the following tests may be done:
Currently there is no cure for psoriasis. But many types of treatment are available, including products applied to the skin, phototherapy, and oral medicines, which can help control psoriasis. Most cases are mild and can be treated with skin products. In some cases, psoriasis can be hard to treat if it is severe and widespread. Most psoriasis returns, even mild forms.
The purpose of treatment is to slow the rapid growth of skin cells that causes psoriasis and to reduce inflammation. Treatment is based on the type of psoriasis you have, its location, its severity, and your age and overall health.
Treatment can also depend on how much you are affected by the condition, either physically (because of factors such as joint pain) or emotionally (because of embarrassment or frustration from a skin rash that may cover a large or visible area of the body).

Depending on what type of psoriasis you have, treatment may also include:
You may need to try different treatments before you find one that works well for you. It's important to discuss your treatment and progress with your doctor.

It's also important to avoid anything that can trigger a flare-up of psoriasis or make the condition worse. Stress, skin injury, infection, and use of alcohol can all contribute to symptom flare-ups. Streptococcal infections, which usually affect the upper respiratory tract, are linked to guttate psoriasis.
Treat scalp or nail psoriasis
Scalp and nail psoriasis can be hard to treat. Both conditions are more likely to improve with medicines taken by mouth (oral medicines). Treatment for the scalp often includes tar shampoos, corticosteroid solutions, or zinc and selenium sulfide shampoos.
