Is It Scalp Psoriasis Or Dandruff

What Causes Plaque Psoriasis

More than half of all psoriasis patients have scalp psoriasis, according to the NPF. Itchy plaques can extend beyond the hairline onto the forehead, neck, and around the ears.

“Most people with scalp psoriasis have it on other parts of their body as well,” says Dina D. Strachan, MD, a dermatologist and assistant clinical professor of dermatology at NYU Langone Medical Center in New York City.

Scalp psoriasis is sometimes confused with seborrheic dermatitis, or dandruff. According to Dr. Strachan, dandruff which causes a flaky, itchy scalp without signs of inflammation tends to itch more than scalp psoriasis. It has a greasy-appearing yellow scale, Strachan says. In contrast, psoriasis whether it’s on your scalp or any other body part tends to have a thick, silvery scale.”

What Is Plaque Psoriasis

Plaque psoriasis, which is recognizable due to the scaly plaques it produces on the skin, is the most common type of psoriasis. An estimated 80 to 90 percent of people with psoriasis develop plaques.

Some people will have more than one type of psoriasis. People who have plaque psoriasis may later develop other forms of the condition, such as psoriatic arthritis.

Usually, the turnover of peoples skin cells takes 21 to 28 days. In people with psoriasis, the body attacks healthy skin cells, so new cells develop every 4 to 7 days.

Psoriasis damages patches of skin, leaving areas of redness and irritation. This damage causes the skin to appear scaly and gray and to peel off.

Plaque psoriasis is not an infection, and it is not contagious. However, irritated patches of psoriasis can become infected.

In some people, an infection or injury to the skin can trigger an outbreak of psoriasis. People experiencing their first psoriasis flare-up may mistake their symptoms for an allergic reaction or skin infection.

Plaque psoriasis. Plaque psoriasis is a chronic autoimmune condition. It appears on the skin in patches of thick, red, scaly skin. Plaque psoriasis can be a very itchy and sometimes painful condition. It also can be embarrassing and doesnt always respond to treatment.

Beside above, how do you get rid of plaque psoriasis? Avoid harsh or scented soaps, which can strip the skins natural oils.

Once a person has had a psoriasis flare, they are likely to have another one. Patches of psoriasis may clear up after a few months, or they may stay the same, get bigger, or spread across the body. In some people, psoriasis will disappear and not return for years.
