What should you know about head and body itching?

Itching with rough, cracked skin can occur when the skin barrier is dry or irritated. Red, inflamed patches may occur with Atopic Dermatitis or Contact Dermatitis. Greasy scale around the scalp, ears, eyebrows, or chest can fit Seborrheic Dermatitis, while silvery plaques may fit Psoriasis. Intense night-time itching with small bumps or burrows needs assessment for Scabies. Hives tend to form raised, shifting welts. A rash that is painful, oozing, crusted, or spreading may signal infection or significant inflammation.

Use lukewarm water and a fragrance-free cleanser, then apply a plain moisturiser while the skin is still slightly damp. Keep nails short and use a cool compress instead of scratching. Pause newly introduced soaps, hair products, fragrances, and detergents until the trigger is clearer. Wear loose, breathable clothing and avoid overheating. Do not apply steroid, antifungal, or anti-parasite products broadly without advice, because the wrong treatment can mask the pattern or irritate skin.

Seek urgent help for itching with facial or tongue swelling, breathing difficulty, faintness, or a rapidly spreading blistering rash. Arrange prompt medical assessment for fever, pus, severe pain, yellow crusting, widespread peeling, or itching that is disrupting sleep and daily activity. A clinician can examine the scalp and body, review medicines and exposures, and decide whether testing or prescription treatment is needed.

Ask what pattern they see, whether a medicine or product could be contributing, and which treatment is suitable for the affected areas. Mention when the itching began, whether anyone close to you itches, and whether it is worse at night.
