What should you know about severe dandruff on scalp?

Dandruff is visible shedding of scalp skin. Larger or persistent flakes may occur with seborrheic dermatitis, which can also cause greasy scale, redness and irritation around the hairline, eyebrows or ears. An itchy scalp and scalp flaking describe symptoms, not a diagnosis. A clinician can check for psoriasis, eczema, contact irritation or infection when the appearance is unusual.

Wash the scalp regularly and follow the directions on a suitable medicated shampoo, allowing it to contact the scalp before rinsing. Avoid scratching, harsh scrubbing and fragranced products that sting. If flakes remain heavy, treatment may include Medicated Shampoo Treatment or Topical Antifungal Treatment after an examination. Keep a note of products used and whether redness, soreness or hair shedding changes.

Arrange a dermatology visit if symptoms do not settle with careful home care, return quickly, or interfere with sleep. Seek prompt assessment for painful swelling, pus, bleeding from scratching, thick plaques, patchy hair loss or a widespread rash. These findings can point to a problem needing different treatment.

Ask whether the scale fits dandruff or seborrheic dermatitis, how long to leave a medicated product on, and what to use if your scalp becomes sore or hair begins shedding.
