What should you know about cause of flaky scalp?

Small white or yellow flakes with mild itch often fit dandruff or seborrheic dermatitis, which can also affect the eyebrows, ears, or sides of the nose. Thick, well-defined scale that extends beyond the hairline may suggest scalp psoriasis. A new product can cause contact dermatitis, especially when burning or redness follows its use. Scalp ringworm may cause scaling with broken hairs, tenderness, or patchy hair loss. Dry air and vigorous washing can worsen visible flakes without being the underlying condition. The scalp examination is more useful than the colour of a flake alone.

Wash regularly with a gentle product and avoid scratching, picking, or sharing combs and hats. If dandruff is likely, a medicated shampoo may help when used as directed and left on the scalp for the recommended contact time. Stop a newly introduced product if it causes burning or a rash. Do not rely on home treatment when there are painful areas, broken hairs, or patchy loss, because a fungal infection needs a different approach from dandruff or psoriasis.

Arrange a review if flaking persists despite appropriate shampoo use, spreads beyond the scalp, or comes with bleeding, thick plaques, crusting, or significant redness. Seek prompt assessment for patchy hair loss, pus, fever, or a painful swollen scalp. Children and people with reduced immunity should be assessed sooner when a fungal infection is possible.

Does the scale look more like dandruff, psoriasis, dermatitis, or ringworm? Should I use a medicated shampoo, and how often? Could a hair product be irritating my scalp? What signs would mean I need prescription treatment?
