Adults and adolescents over 12: wet hair, apply a small amount to the scalp, massage into a lather, leave for 3–5 minutes, then rinse thoroughly. For dandruff, use every 3 or 4 days for 2–4 weeks; to help stop dandruff returning, use once every 1–2 weeks. Use your usual shampoo for any other washes in between.

Not for children under 12. Do not use if you have had a bad reaction to any ingredient. If it gets into the eyes, bathe them gently with water. Contains sodium lauryl ether sulphate, which may cause stinging or burning or increase reactions to other products used on the same area. If you have been using a steroid lotion or cream on your scalp, reduce it gradually over 2–3 weeks as you start this shampoo. See a doctor or pharmacist if the scalp has not cleared within 4 weeks. Possible side effects include scalp irritation, dryness and changes in hair texture.
