What should you know about extreme dandruff?

Dandruff produces visible flakes from an irritated, shedding scalp. Seborrheic Dermatitis can add redness, itch, and greasy scale around the scalp, hairline, ears, eyebrows, or sides of the nose. Product buildup, dry air, psoriasis, eczema, or contact irritation can look similar. Heavy flakes do not by themselves identify the cause, so note whether the scale is dry or oily and whether the skin underneath is red or sore.

Use a Medicated Shampoo Treatment as directed on its label or by a clinician, allowing the lather enough contact time to work before rinsing. Apply it to the scalp rather than only the hair lengths. Once controlled, some people need a maintenance schedule to reduce return of flakes. A Topical Antifungal Treatment may be considered when yeast-related inflammation is suspected. Avoid scratching, harsh scrubs, and fragranced products that sting. Wash gently and rinse thoroughly, especially when using textured or densely styled hair.

Book a dermatology appointment if flakes persist despite correct medicated washing, cover large areas, or occur with marked redness, thick plaques, pain, crusting, oozing, or patchy hair loss. Seek prompt care for rapidly worsening swelling, pus, fever, or severe tenderness. A clinician can distinguish dandruff from psoriasis, infection, or contact dermatitis and adjust treatment safely.

Does this look like dandruff or Seborrheic Dermatitis? Which active shampoo ingredient suits my scalp? How long should I use it, and do I need maintenance care? Could a product or hair treatment be causing the irritation?
