What should you know about red psoriasis scalp?

Scalp psoriasis may extend beyond the hairline and produce thick, dry scale over red or darker inflamed skin. Itch, tenderness, flaking, peeling, or small cracks can occur. Scratching may cause bleeding and can make irritation worse. Dandruff, seborrhoeic dermatitis, eczema, and fungal infection can resemble it, so scale alone is not enough to identify the condition.

Look for changes on the elbows, knees, nails, or other skin areas, and tell the clinician about joint stiffness or swelling. These details can help place scalp symptoms in context.

Loosen scale with a clinician-recommended scalp product rather than scraping it off. Wash gently, rinse thoroughly, and avoid very hot water, tight hairstyles, harsh chemicals, and vigorous brushing. Keep nails short and try not to scratch. Treatments may include medicated scalp preparations or other prescription options, chosen according to thickness, extent, and previous response.

A clinician can show you how to part the hair and apply treatment directly to the scalp rather than coating the hair.

Arrange an assessment if redness is new, persistent, painful, oozing, spreading, or associated with noticeable hair loss or joint symptoms. Seek prompt care for severe swelling, pus, fever, or rapidly worsening pain. Urgent attention is needed for facial swelling or breathing difficulty after a product or medicine.

Does this look like scalp psoriasis or another scalp rash? How should I remove scale, where exactly should treatment go, and could my joint symptoms be related?
