What should you know about sunburned scalp itchy?

Sunburn can inflame the scalp and later cause tightness, dryness, flaking, or itch as the surface repairs. A tender scalp may feel worse when hair is brushed or when shampoo contains fragrance. Itch can also occur with dandruff, seborrheic dermatitis, scalp psoriasis, folliculitis, or head lice, so the timing and visible findings matter.

Check gently for redness, peeling, blisters, crusting, pus, thick scale, or moving insects and nits. Avoid scratching because broken skin can become irritated or infected. An itchy scalp is a symptom, not a diagnosis; a sunburn can coexist with a separate scalp condition.

Stay out of direct sun and cover the scalp with a loose, breathable hat. Rinse with cool or lukewarm water, use a mild fragrance-free shampoo, and pat rather than rub. Cool compresses may soothe exposed areas. Do not pick flakes, scratch blisters, apply essential oils, or use hair dye on irritated skin.

If flaking continues after the burn settles, a clinician may recommend a medicated shampoo suited to the cause. Do not use head-lice treatment simply because the scalp itches; confirm lice first and follow the product instructions carefully. Keep combs and towels separate until lice have been ruled out if there is a close-contact concern.

Seek prompt medical advice for extensive blisters, severe pain, pus, spreading redness, fever, facial swelling, or a scalp wound that is worsening. Arrange a review when itch persists after healing, causes sleep loss, comes with thick scale or hair loss, or follows possible exposure to lice. Urgent help is needed for fainting, confusion, or breathing difficulty.

Ask whether the itch fits sunburn or another scalp condition, which shampoo is appropriate, and how to protect the scalp without trapping heat. If lice are suspected, ask how to confirm them and whether household contacts need advice.
