Dry scalp or dandruff? Dermatologist explains how to tell them apart this winter

An itchy, flaky scalp in winter isn't always dandruff, says Dr Hina Kukreja of Zurie Skin Clinic. Dry scalp comes from moisture loss due to cold, dry air, hot showers or harsh daily shampoos, causing small white flakes and tightness. Dandruff is a reaction to the Malassezia fungus. Treating both the same way can worsen irritation and delay relief.
