Plaque psoriasis of the scalp
What is Plaque Psoriasis of the Scalp?
Plaque psoriasis is a common inflammatory skin disorder that affects the scalp. It is caused by the overproduction of skin cells that form raised, red and scaly patches on the scalp. It can cause skin irritation, itching, and in some cases, hair loss. This inflammatory skin condition can occur at any age and is most common in adults.
Symptoms of Plaque Psoriasis of the Scalp
The most common symptom of plaque psoriasis on the scalp is raised, itchy, red patches called plaques. These patches can vary in size and typically appear on both sides of the scalp, although they can spread to other areas. Plaques can be painful, and you may also experience burning, stinging, and soreness. In some cases, plaque psoriasis of the scalp can cause hair loss, as it destroys hair follicles.
Causes of Plaque Psoriasis of the Scalp
The exact cause of plaque psoriasis of the scalp is unknown. However, scientists think that it is caused by a combination of genetic and environmental factors. The immune system plays an important role in the development of plaque psoriasis, as it can cause the overproduction of skin cells in certain areas of the scalp.
Risk Factors for Plaque Psoriasis of the Scalp

Treatments for Plaque Psoriasis of the Scalp
Plaque psoriasis of the scalp can be treated with topical medications, light therapy, and biologic medications. Topical treatments can be used to reduce inflammation and relieve symptoms.

Biologic medications, which are injected, can help reduce the production of skin cells and reduce inflammation.
