Scalp Psoriasis: In at least half of the people who have Psoriasis skin disease, the scalp is affected. Scalp psoriasis can range from mild, dandruff-like scaling to crusty plaques that extend beyond your hairline to your forehead or neck. This type of disease can be very itchy. Using a medicated shampoo may help with scalp psoriasis.
Be prepared for flare-ups: Having a long-term disease that can flare up unpredictably can be frightening. But knowledge is power, so the more you know about the possible effects of this disease, the better prepared you will be to handle flare-ups and possibly prevent other health issues.
Psoriasis Skin Plaques: The most common sign of this disease is a psoriasis plaque, a raised, red skin patch covered by a silvery-white coating. Eight out of 10 people with this disease have plaques. These patches can form anywhere on your skin but are most likely to show up on your knees, elbows, lower back, and scalp. You may have several patches that join together to form a big patch. Plaques are itchy, but resist scratching them because scratching can make them become thicker.
Nail Changes: As many as half of all people with this disease experience nail changes caused by the condition. Changes in your nails may include pitting (holes), alterations in color and shape, thickening, and separation of the nail from the nail bed. If your nails become affected, try keeping them trimmed short and protect them by wearing gloves while working with your hands.
