I Have a Lot of Dandruff: What Should I Know?

Dandruff produces visible flakes and may come with itch, but the scalp is not always inflamed. Seborrheic dermatitis can cause greasy scale, redness, and involvement of the eyebrows, ears, or sides of the nose. Contact dermatitis from hair dye or styling products may burn or itch. Thick plaques, broken hairs, or patchy hair loss suggest that a clinician should consider other scalp disorders. Read about [Dandruff](/conditions/dandruff/), [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/), [Itchy Scalp](/symptoms/itchy-scalp/), and [Flaky Scalp](/symptoms/scalp-flaking/).

Use a [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) as directed, allowing the lather to remain on the scalp for the product's stated contact time. Rinse thoroughly and avoid scratching, very hot water, and heavy product buildup. If scale is persistent, a clinician may recommend [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). Different active ingredients suit different scalp findings, and overuse can irritate the skin.

Book a dermatology visit if flaking persists despite correct shampoo use, returns quickly, or comes with marked redness, pain, oozing, thick plaques, or hair loss. Seek prompt care for facial swelling, widespread blistering, or signs of infection such as increasing warmth and pus. A persistent itchy scalp should not be diagnosed from flakes alone.

Ask which diagnosis best fits the scale, how often to use a medicated product, whether your hair products could be causing irritation, how to treat involved facial skin, and what to do when symptoms return.
