Dry hair and dandruff: understanding the difference

Dry hair may feel rough, frizzy, brittle, or difficult to detangle because the fibre has lost moisture or been stressed by heat, colouring, or chemical processing. Dandruff produces visible scalp flakes and may cause itch. Seborrheic dermatitis can add redness or greasy scale around the hairline, ears, or eyebrows. Flaking is not proof that the hair itself is dry, and frequent washing is not the only possible trigger.

Apply conditioner to the lengths rather than the scalp, limit high heat, detangle gently, and avoid tight styles that pull on the roots. For scalp flakes, use a gentle routine and ask a pharmacist or clinician about medicated shampoo treatment. A topical antifungal treatment may be considered when a yeast-related scalp condition is suspected. Follow product directions and stop if burning or marked irritation develops.

Arrange review for persistent itch, painful redness, thick scale, sores, oozing, patchy hair loss, or symptoms that continue despite sensible care. Seek prompt help for rapidly spreading swelling or severe tenderness. Assessment can separate dandruff from seborrheic dermatitis, contact irritation, psoriasis, or infection and can protect the hair and scalp from further damage.

Ask whether the flakes are dandruff or another scalp condition, whether your hair routine is causing breakage, which active ingredient fits your scalp, and how to use conditioner without worsening scale.
