What should you know about shampoos for dry scalp and oily hair?

Oil is produced at the scalp, while the mid-lengths and ends receive less of that natural coating. Washing the whole hair shaft aggressively can leave the lengths rough even when the roots become greasy quickly. Heat, colouring, chemical treatments and styling products can add to that dry feeling.

Visible flakes may reflect irritation, dandruff or seborrheic dermatitis rather than a lack of oil. A tight or burning scalp after a new product suggests sensitivity, especially if redness or a rash appears.

Apply shampoo mainly to the scalp and let the rinse pass through the lengths. Use fingertips, not nails, and rinse thoroughly. Place conditioner from the mid-lengths to the ends; keep heavy products away from oily roots. If flakes or itch continue, a medicated shampoo treatment may be more useful than repeatedly switching cosmetic shampoos. Follow its directions and stop if it causes marked irritation.

Arrange an assessment if flaking, itch or redness persists, spreads to the hairline or ears, or keeps returning despite a consistent routine. Seek prompt care for painful swelling, crusting, pus, bleeding, or patchy hair loss. These features can signal a scalp condition that needs targeted treatment rather than a different conditioner.

Ask whether the problem is product irritation, dandruff or seborrheic dermatitis, how often to wash, where to apply conditioner, and whether a medicated shampoo is appropriate.
