Dry, itchy dandruff scalp treatment: what to know

Dandruff causes visible scalp flaking with itch and can be more noticeable when the scalp is oily or irritated. Seborrheic dermatitis is a related inflammatory condition that may also affect the eyebrows, ears, or sides of the nose. Dryness from harsh cleansing or product build-up can look similar. The colour, thickness, and location of flakes, along with redness or soreness, help a clinician distinguish these patterns. Scratching can break the skin and increase discomfort.

Wash the scalp regularly with lukewarm water and avoid vigorous scratching. A medicated shampoo may contain an ingredient that loosens scale or reduces the organisms and inflammation associated with dandruff; follow the product directions, including any recommended contact time. Rinse thoroughly and stop if it causes marked irritation. If flakes remain, the scalp is very inflamed, or the condition affects other areas, a clinician may recommend topical antifungal treatment or another prescription approach. Keep products out of the eyes.

Arrange a review when flaking and itch persist despite careful use of an appropriate product, return repeatedly, or are accompanied by thick plaques, bleeding, pus, painful bumps, or patchy hair loss. Seek prompt care for fever, rapidly spreading redness, or severe tenderness. A scalp examination can prevent treating psoriasis, infection, or another condition as simple dandruff.

Does this look like dandruff or seborrheic dermatitis? Which shampoo ingredient fits my scalp? How long should I try it before review? Could the redness, scale, or hair changes suggest another condition?
