What should you know about powdery dandruff?

Dandruff produces loose white or grey flakes that fall from the scalp and may come with itching. Seborrheic dermatitis can add redness, soreness, or greasy yellowish scale, and may affect the eyebrows, ears, or sides of the nose as well as the scalp. Dry air, irritating products, infrequent washing, or sensitivity to hair products can change how much scale you see.

A sharply bordered patch, thick scale, broken hairs, oozing, or hair loss suggests that the problem may be more than simple dandruff. A clinician can distinguish these patterns from psoriasis, fungal infection, or contact irritation.

Wash the scalp regularly with a gentle shampoo and rinse thoroughly. If flakes continue, a Medicated Shampoo Treatment may help when used exactly as directed; allow the product the recommended contact time rather than scrubbing hard. Avoid scratching, very hot water, and new fragranced products while the scalp is irritated.

If scale is accompanied by persistent itch, a clinician may consider a Topical Antifungal Treatment or another approach. Keep a note of products used, washing frequency, and areas affected so the pattern is easier to assess.

Arrange a dermatology review if flakes persist despite careful shampoo use, return quickly, or spread beyond the scalp. Seek earlier assessment for pain, crusting, bleeding, pus, marked redness, patchy hair loss, or thick plaques. Sudden facial swelling or breathing difficulty needs urgent help.

Ask whether the appearance fits Dandruff or Seborrheic Dermatitis, which shampoo ingredient is suitable, how often to use it, and how long to try it. Mention itching, facial scale, hair loss, allergies, and any recent change in hair products.
