What should you know about solution for itchy scalp?

Flakes and an oily or irritated scalp may occur with dandruff or seborrhoeic dermatitis. Thick, defined plaques can fit scalp psoriasis. Small inflamed bumps around hairs may suggest folliculitis, while intense itching with visible nits or moving insects can point to head lice. Hair products, fragrance, sweat, and scratching can also irritate the scalp without an infection.

Use a gentle shampoo, rinse thoroughly, and avoid picking or vigorously scratching. Pause newly introduced dyes, oils, sprays, or fragranced products if symptoms began after using them. A pharmacist or dermatologist can help select a medicated shampoo when flaking or inflammation persists; follow its label directions and keep it away from the eyes. Do not share combs, brushes, hats, or pillows if lice are possible. See [Dandruff](/conditions/dandruff/), [Scalp Psoriasis](/conditions/scalp-psoriasis/), and [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) for related options.

Arrange a clinical assessment for pus, spreading redness, painful swelling, broken skin, patchy hair loss, or symptoms that do not settle with gentle care. Seek prompt help if the scalp becomes markedly swollen or you feel unwell. A clinician can distinguish [Folliculitis](/conditions/folliculitis/) from [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/) and advise whether [Head Lice Treatment](/treatments/medical-dermatology/head-lice-treatment/) is appropriate.

Could this be dandruff, psoriasis, folliculitis, contact irritation, or lice? Which shampoo or scalp treatment suits my symptoms? Should I stop any hair products, and what changes would mean I need a follow-up?
