What should you know about a flaky but not itchy scalp?

Dandruff and seborrheic dermatitis can cause visible flakes with little or no itch, particularly when the scalp is mildly inflamed. Scalp psoriasis may create thicker, dry scale and sharply defined patches. Product residue, a dry scalp, or recent changes in shampoo, styling products, or hair colour can also make flakes visible without much discomfort.

Folliculitis affects hair follicles and may cause small spots, crusting, or tenderness rather than itch. Head lice can be present before itching becomes noticeable, so moving specks or attached eggs need a careful look. Scalp ringworm may cause scale, broken hairs, or patchy hair loss and should be assessed even when itch is absent.

Brush away loose scale gently and wash with lukewarm water; avoid scraping the scalp or layering oils and styling products over it. Pause newly introduced fragranced products or hair treatments and observe whether the flaking settles. Check the scalp in good light for redness, thick plaques, spots, attached eggs, broken hairs, or a widening area of hair loss.

If dandruff or seborrheic dermatitis seems possible, a pharmacist or clinician can advise whether medicated shampoo therapy is suitable and how often to use it. Do not share combs, brushes, hats, towels, or bedding if lice or an infection is possible. Treating a suspected cause is more useful than repeatedly changing cosmetic products.

Book a clinical review if flakes continue despite gentle care, recur often, or occur with redness, plaques, crusts, spots, tenderness, broken hairs, or hair loss. Seek prompt care for pus, marked swelling, fever, severe pain, or a rapidly expanding patch. A clinician can distinguish surface scale from a follicle problem and check for lice or infection when needed.

Ask whether the scale looks more like dandruff, seborrheic dermatitis, scalp psoriasis, folliculitis, head lice, or ringworm; whether a test is needed; and which shampoo or treatment is appropriate. Mention recent product changes, contact with affected people, hair shedding, broken hairs, and any treatments already tried.
