My scalp is very dry and flaky

Fine white flakes after a new shampoo, dye, or styling product can point to irritation or dryness. Greasy scale with itch around the scalp, ears, eyebrows, or nose is more consistent with seborrheic dermatitis. Thick, sharply defined scale may occur with scalp psoriasis. Tender patches, broken hairs, or areas of hair loss need assessment for scalp ringworm. Dandruff commonly causes visible flakes without the thicker plaques or marked inflammation seen in some other conditions.

Pause newly introduced fragranced products and avoid scratching, picking, very hot water, and tight hairstyles. Wash gently and rinse thoroughly. A pharmacist or clinician can help you choose a medicated shampoo when dandruff or seborrheic dermatitis is suspected; follow its label directions and allow it contact with the scalp as directed. If flakes persist, note whether they are dry or greasy, where they occur, and whether redness, pain, or hair loss is developing.

Arrange a dermatology review for persistent flaking, thick scale, significant redness, bleeding, soreness, crusting, or patchy hair loss. Seek prompt care if the scalp becomes rapidly swollen, hot, very painful, or drains pus, or if you feel unwell. These features can need a different treatment than routine dry-skin care.

Ask whether the scale resembles dandruff, seborrheic dermatitis, scalp psoriasis, or an infection; whether a medicated shampoo is suitable; and which product ingredients or hair practices you should avoid while the scalp settles.
