Dry itchy scalp relief

The scalp can become tight and flaky after hot showers, over-washing, harsh cleansers, sweat, or a new styling product. Dandruff and seborrheic dermatitis may cause flakes with irritation; scalp psoriasis may produce thicker scale. Pimple-like lesions suggest folliculitis, while nits or itch among household contacts suggests head lice. These conditions can look alike, so symptom relief alone does not establish a diagnosis.

Use lukewarm water, a gentle fragrance-free shampoo, and fingertips rather than nails. Rinse well and pat dry. Stop recently added dyes, sprays, and fragranced products for a short period, and loosen tight styles. A pharmacist or clinician can advise whether a medicated shampoo treatment is appropriate and how to use it safely. Do not pick flakes or squeeze bumps, since this can damage the skin and invite infection.

Seek an appointment when symptoms keep returning, do not improve with a gentle routine, or interfere with sleep or daily activities. Prompt assessment is appropriate for open sores, pus, bleeding, painful swelling, hair loss in patches, fever, or redness spreading beyond the scalp. Urgent help is needed for breathing difficulty or sudden facial swelling.

What pattern do you see, and does it fit dandruff, dermatitis, psoriasis, folliculitis, or lice? Which treatment should I try first, and how will I know it is helping?
