Dry Skin and Dandruff: What Should You Know?

A dry scalp may feel tight and shed small, light flakes, especially after harsh cleansing or exposure to dry air. Dandruff commonly causes recurring flakes with itch and may affect an oily scalp. Seborrheic dermatitis can cause more persistent redness, greasy scale and involvement of the eyebrows, ears or sides of the nose.

Flaking can also follow irritation from hair dye, styling products or vigorous scratching. The appearance of the scale, scalp redness, itch and distribution help a clinician distinguish these possibilities. An itchy or flaky scalp is a symptom, not a diagnosis by itself.

Wash gently and rinse shampoo thoroughly. Avoid very hot water, picking flakes and applying heavy oils if they worsen greasiness or scaling. A medicated shampoo may be recommended for dandruff; follow its label or clinician’s instructions and allow appropriate contact time before rinsing. Keep a note of products that preceded irritation.

If inflammation or yeast-related overgrowth is suspected, a clinician may suggest a topical antifungal treatment. Do not use multiple active scalp products at once without guidance, because irritation can make flaking harder to interpret.

Book an assessment when flaking lasts despite a consistent routine, the scalp is very itchy, sore or bleeding, or hair loss appears in patches. Seek prompt care for pus, marked swelling, fever, a rapidly spreading rash or painful crusting.

Does this look more like dandruff, dry scalp or seborrheic dermatitis? Which shampoo should I use and how often? Could a hair product be causing irritation? Do I need treatment for inflammation or yeast?
