Dry hair, oily scalp and dandruff: what to know

Oil is made at the scalp, whereas the mid-lengths and ends depend on natural oils spreading along the hair. Washing, heat styling, colouring, friction, or harsh products may leave the lengths rough even when the roots become greasy quickly.

Dandruff causes visible flakes and may bring itching or irritation. Seborrheic dermatitis is a related inflammatory condition that can affect oily scalp areas and may cause more persistent redness, scale, or discomfort. Flaking does not prove that the hair itself is dry.

Wash the scalp as often as needed to control oil and buildup, concentrating shampoo at the roots and rinsing thoroughly. Use lukewarm water, avoid scratching, and apply conditioner mainly from the mid-lengths to the ends.

A clinician or pharmacist can guide you toward a suitable medicated shampoo treatment for dandruff. Follow its directions, allow the product appropriate contact with the scalp, and stop or seek advice if burning or marked irritation develops. Limit hot tools and tight hairstyles while the hair recovers.

Arrange a dermatology assessment if flakes persist despite consistent care, or if the scalp becomes very itchy, painful, red, swollen, crusted, or oozing. Seek prompt advice for patchy hair loss, broken hairs, or sores, because these findings may need a different diagnosis and treatment.

Ask whether the scale fits dandruff or seborrheic dermatitis, how often to use a medicated shampoo, and which conditioner or styling products are least likely to irritate your scalp.
