What should you know about lots of dandruff?

Dandruff produces visible white or yellowish flakes, often with itch or a tight-feeling scalp. Seborrheic dermatitis can cause more persistent scale, redness, and greasy areas around the scalp, hairline, ears, or eyebrows. Dry air, infrequent washing, product buildup, and sensitivity to hair products can make flakes more noticeable. Scratching may create soreness and small breaks in the skin, so the amount of flaking does not by itself identify the cause.

Wash the scalp regularly and apply a medicated shampoo to the scalp rather than only the hair lengths. Leave it in for the time stated on its label, then rinse thoroughly. Rotate or change active ingredients only with professional guidance if one option irritates your skin. Avoid picking scales, vigorous scratching, and heavy oily products that worsen buildup. A clinician may consider topical antifungal treatment when yeast-related inflammation is suspected.

Arrange a dermatology assessment if flaking persists despite careful use of an appropriate shampoo, spreads beyond the scalp, or comes with marked redness, pain, oozing, thick plaques, or patchy hair loss. Seek prompt care for rapidly worsening swelling, fever, or pus. These features can point to infection or another scalp condition needing examination.

Ask whether the scale fits dandruff or seborrheic dermatitis, which shampoo ingredient suits your scalp, how often to use it, and whether redness or hair loss needs a closer examination.
