Dry, itchy, burning scalp: what to know

New shampoo, hair dye, styling products, heat, or frequent washing can irritate the scalp and leave it tight or burning. Dandruff and seborrheic dermatitis may cause flakes with itch, while scalp psoriasis can produce thicker, well-defined scaling. Folliculitis tends to cause tender or itchy bumps around hairs. Head lice can cause intense itching, especially around the ears and the nape; close inspection may show attached nits. These conditions can overlap, so the appearance of the scale, bumps, redness, and distribution matters.

Pause recently introduced products and use lukewarm water with a gentle, fragrance-free cleanser. Avoid scratching, picking flakes, tight hairstyles, and hot tools while the skin settles. Keep combs, hats, and pillowcases personal until head lice has been considered. A pharmacist or clinician can help choose a medicated shampoo when dandruff is suspected; use it according to its label and keep it away from the eyes. Do not apply household oils or harsh antiseptics to broken skin.

Arrange a medical review if burning persists, symptoms recur, or the scalp develops painful bumps, crusting, oozing, bleeding, hair loss, or thick plaques. Seek prompt care for rapidly spreading redness, marked swelling, fever, or severe pain. A clinician can examine the scalp and decide whether treatment for inflammation, infection, or lice is appropriate.

Could a product reaction, dandruff, psoriasis, folliculitis, or lice explain the pattern? Should I stop any current hair products? Which treatment is suitable for my scalp and how should it be used? What changes would mean I should return sooner?
