Normal skin replacement takes about 30 days. In people suffering from psoriasis, the skin replaces itself much more rapidly (3-4 days) and the telltale signs of psoriasis emerge.

Psoriasis usually develops on the scalp, elbows, knees and lower back — and often appears in the same place on both sides of the body. The most common form is called plaque psoriasis. This persistent condition begins as small red bumps. As these grow larger, scales begin to form. These scales flake off easily and often, causing the red areas to grow larger still — and the cycle continues. Psoriasis can often be effectively controlled with steroid treatment.

At least fifty percent of people with psoriasis on their bodies also have scalp psoriasis. Scalp psoriasis is often mistaken for dandruff and can range from very mild with fine scaling to very severe with thick, crusted plaques. Steroid shampoo offers convenient and powerful treatment for scalp psoriasis.

If you suspect you have some form of psoriasis, use our Self-Assess Your Skin Tool to help determine your level of severity; then visit your dermatologist. If you don't have a dermatologist, locate one in your area with the DermFinder.
