What should you know about cure for itchy scalp?

Dandruff and seborrheic dermatitis can bring flakes, itch, and greasy or dry scale. Scalp psoriasis often causes thicker scale and sharply outlined areas. Head lice cause itching and may leave nits attached close to hairs. Folliculitis can create tender, itchy bumps around individual hairs.

Hair dye, dry shampoo, styling products, and frequent scratching can inflame the scalp. The timing of symptoms, visible scale, bumps, nits, and any hair loss help distinguish these causes.

Wash with lukewarm water and a gentle product, rinse thoroughly, and avoid scratching or picking. Stop a new product if symptoms followed its use. Medicated shampoo treatment can help selected flaking conditions; apply it to the scalp rather than only the hair and follow the directions.

If live lice or nits are found, head lice treatment and household measures may be needed. Do not share combs, brushes, hats, or pillows during assessment. Persistent bumps, crusting, or hair loss warrant a clinical examination.

Get medical advice for pus, bleeding, severe tenderness, spreading redness, swollen glands, patchy hair loss, or a rash that is not settling. Prompt assessment is sensible when several household members itch or when a child has suspected lice or a scaly bald patch.

Ask what the scalp findings show, whether lice or infection needs testing, which shampoo or medicine fits the diagnosis, and how to protect family members if an infestation is present.
