What should you know about removing dandruff?

Dandruff causes visible flakes and may cause itching, irritation, or an oily or dry-feeling scalp. It can overlap with seborrheic dermatitis, which may also affect the eyebrows, ears, sides of the nose, or chest. Product irritation, psoriasis, eczema, and fungal infection can look similar, especially when scaling is thick or extends beyond the scalp.

Flakes are easier to control when treatment reaches the scalp rather than only the hair. Scratching can break the skin, increase irritation, and create a route for infection. See [Flaky Scalp](/symptoms/scalp-flaking/) and [Itchy Scalp](/symptoms/itchy-scalp/) for related symptoms.

Use a suitable [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) according to its label or your clinician’s instructions. Work it into the scalp, leave it on for the directed contact time, and rinse thoroughly. Regular use matters; once controlled, some people need a maintenance routine. Avoid scratching, very hot water, heavy product build-up, and hair products that burn or sting.

If standard shampoo care does not control the problem, a clinician may consider [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) or another diagnosis. Do not share medicated products or apply them to broken skin unless advised.

Arrange a dermatology review if symptoms continue despite correct use, or if there are thick plaques, marked redness, hair loss, bleeding, pus, painful cracks, or scaling on the face or body. Seek prompt care for fever, rapidly spreading redness, or swelling. A scalp rash that is sharply defined or affects nails and joints may need assessment for psoriasis.

Ask whether the pattern is dandruff, seborrheic dermatitis, psoriasis, eczema, or infection; how often to use a medicated shampoo; how long to leave it on; and what maintenance plan fits your scalp. Mention hair dye, oils, new products, and any broken skin.
