Psoriasis and dry scalp: what to know

Scalp psoriasis is an inflammatory skin condition that may extend beyond the hairline or appear behind the ears. The skin can shed thick, pale scale over a red or darker-looking base, while scratching may leave soreness, bleeding, or temporary hair shedding from trauma. Ordinary dry skin tends to produce finer flakes without the same raised, clearly defined patches. Dandruff and contact irritation can look similar, so appearance alone cannot confirm the cause.

Wash with lukewarm water and a gentle, fragrance-free cleanser. Soften adherent scale with a suitable emollient or product recommended by a clinician, then loosen it with fingertips rather than scraping with nails. Follow prescribed scalp treatments exactly, because some medicines are intended for short courses or particular areas. Keep nails short, avoid picking, and pause hair dye or strongly scented products if they sting. Tracking itch, scale, and triggers can make follow-up more useful.

Arrange a medical review if the scalp is painful, repeatedly bleeding, oozing, crusted, or developing new areas despite careful treatment. Seek prompt advice for sudden extensive inflammation, fever, or eye involvement. A clinician can distinguish psoriasis from infection, eczema, seborrhoeic dermatitis, or a product reaction and can check whether joint symptoms are also present.

Could this be scalp psoriasis or another cause of flaking? Which treatment should touch the scalp, and how should it be applied around the hair? What should I do if scale returns or treatment irritates my skin?
