Excessive dandruff on the scalp: what to know

Dandruff produces white or grey flakes that may fall onto clothing, with itch or scalp irritation in some people. Oilier skin, cold or dry conditions, stress, and infrequent washing can make it more visible. Dandruff is not caused by poor hygiene and is not usually contagious.

Redness, greasy scale, and irritation around the scalp, ears, eyebrows, or sides of the nose can fit seborrheic dermatitis. Thick plaques, sores, hair loss in patches, or severe inflammation suggest that another scalp condition may need examination.

Use a Medicated Shampoo Treatment according to its instructions, allowing the lather to remain on the scalp for the recommended contact time before rinsing. Different active ingredients work in different ways, and rotating or changing products may be useful when one approach is insufficient.

A clinician may recommend Topical Antifungal Treatment when yeast sensitivity contributes to the scale. Avoid scratching, very hot water, and harsh fragranced products that can inflame the scalp. Once controlled, continued treatment at a suitable interval may help prevent recurrence.

Seek medical advice if flaking does not improve with careful use of an appropriate shampoo, keeps returning, or causes substantial itch, pain, redness, or sleep disruption. Arrange prompt assessment for bleeding, pus, thick crusts, patchy hair loss, or a painful swollen scalp.

Ask whether the pattern is dandruff, seborrheic dermatitis, psoriasis, or another condition; which ingredient to try; and how long to use it. Mention any hair loss, skin disease, allergies, or products that make the scalp worse.
