Choosing shampoo for an itchy scalp

Itch may follow product irritation, sweat, dryness or scratching. It can also be a presentation of Dandruff, Folliculitis, Head Lice, Scalp Psoriasis or Seborrheic Dermatitis. Look for clues such as flakes, oily scale, spots around hairs, thick patches, visible nits or tenderness, but avoid diagnosing from one clue alone.

Begin with a mild, fragrance-free shampoo and rinse carefully. Work it into the scalp with fingertips, leave it on only for the time stated on the label, and stop if burning or a new rash develops. When flaking or greasy scale accompanies itch, ask a clinician or pharmacist about Medicated Shampoo Treatment. If live lice are found, ordinary shampoo is not enough; follow advice for Head Lice Treatment and handle household contacts as directed.

Book a review for persistent itch, open sores, crusts, oozing, painful bumps, spreading redness, fever, swollen glands or areas of hair loss. A sudden reaction after a product needs prompt advice, especially if facial swelling or breathing difficulty occurs; seek emergency help for those severe allergy symptoms.

Ask what findings point to the cause, whether you need a medicated shampoo, how to use it safely, and when to return if the itch continues.
