Itchy scalp eczema: what it can mean and how to help

Eczema reflects an irritated skin barrier and may feel tight, dry, or intensely itchy. Scratching can create cracks, crusting, and temporary hair shedding from broken hairs. Contact eczema can follow exposure to hair dye, fragrance, styling products, or a new shampoo. Seborrheic dermatitis often affects oily areas and produces greasy scale, while scalp psoriasis may form thicker plaques. The appearance and distribution help a clinician separate these conditions.

Wash with lukewarm water and a mild, fragrance-free cleanser. Pause recently introduced dyes, oils, sprays, and fragranced products. Pat the scalp dry instead of rubbing it, keep nails short, and use a cool compress when the urge to scratch is strong. Do not apply steroid or antifungal products to the scalp without advice on the correct strength and duration; treatment depends on the diagnosis and your medical history.

Book an appointment when symptoms keep returning, spread beyond the hairline, cause marked scale, or do not settle after removing an irritant. Prompt care is sensible for painful cracks, pus, fever, swollen glands, or patchy hair loss. Get urgent help for breathing difficulty or swelling of the lips, tongue, or face after a product.

Does this look like eczema, contact dermatitis, seborrheic dermatitis, or psoriasis? Should I stop a particular product? What treatment is suitable for the scalp, and how should I prevent scratching?
