Products to get rid of dandruff: what to know

Dandruff causes visible scalp flaking, sometimes with itch, without necessarily causing a thick rash. Seborrheic dermatitis can cause more persistent inflammation, greasy scale, and redness around the scalp, ears, eyebrows, or nose. Dryness, psoriasis, contact irritation, and infection can look similar, so flakes alone do not identify the cause.

Choose a medicated shampoo with an appropriate active ingredient and massage it onto the scalp rather than only the hair. Leave it in for the label’s contact time, then rinse well. Use the recommended schedule and reduce frequency only when symptoms are controlled. Avoid scratching and stop a product that causes swelling, blistering, or marked burning. A clinician may recommend medicated shampoo therapy or topical antifungal treatment when needed.

Arrange an examination for painful areas, thick plaques, oozing, pustules, patchy hair loss, or a rash that extends beyond the scalp. Seek review when itchy scalp or flaky scalp continues despite correct product use, because a different diagnosis or prescription plan may be needed.

Ask which condition best explains your flakes, how long to leave shampoo on, whether you need maintenance use, and whether another hair or skin product could be irritating your scalp.
