Scalp Psoriasis

An itchy scalp can result from several conditions, the most chronic and bothersome being scalp psoriasis—a skin disorder caused by an overactive immune response. Scalp psoriasis leads to red, inflamed patches covered with thick, silvery-white scales that may extend beyond the hairline. The itching can range from mild to severe and may cause discomfort, embarrassment, and secondary problems such as hair loss due to scratching.

Causes of Itchy Scalp / Scalp Psoriasis

* Immune System Dysfunction: Overactive immune response causing rapid skin cell turnover.

* Genetics: Family history of psoriasis or autoimmune disorders.

* Environmental Triggers: Cold weather, dry air, or pollution.

* Stress: Psychological stress can worsen flare-ups.

* Infections: Strep throat and other infections may trigger psoriasis.

* Medications: Beta-blockers, lithium, and certain antimalarials.

* Skin Injury (Koebner Phenomenon): Scratches, cuts, or burns can trigger lesions.

* Lifestyle Triggers: Smoking, alcohol, and unhealthy diet.

* Red Patches: Inflamed areas on the scalp, sometimes extending to the forehead, back of the neck, or behind the ears.

Diagnosis of Itchy Scalp / Scalp Psoriasis
