    Frequently Asked QuestionsPsoriasis

    What is the main cause of psoriasis?

    Experts aren’t sure exactly, but it’s clear that genetics and external triggers like stress, certain medications, and infections, among others, can cause the onset of and flare ups associated with psoriasis. Like many diseases, psoriasis is caused by a haywire immune system.

    What’s the difference between psoriasis and eczema?

    Both psoriasis and eczema are skin conditions that can be itchy and debilitating. But the similarities stop there. Psoriasis occurs typically as patches of thickened, scaly, inflamed, silver or red skin while eczema is dry and flaky in mild cases and red and irritated in those that are more severe. Eczema is also more common, leaving 10-15 % of adults and 20% of children scratching, compared to psoriasis, which affects around 3% of the population and usually hits later in life.

    Is there a blood test for psoriasis?

    No. There is no test or tool to determine if you have psoriasis. Instead, your MD will determine that you have psoriasis and its type by looking at your skin with the naked eye and possibly via a microscopic biopsy.

    What’s the best shampoo for scalp psoriasis?

    Medicated shampoos are more effective for scalp psoriasis than traditional shampoo, but your doctor may prescribe other topicals including corticosteroids, scale softeners, a vitamin D3-based medicine called calcipotriene or tazarotene.
