Transfer the refill into the original bottle before use. Spray an appropriate amount onto dry or partially dry hair. Check the direction of the nozzle and hold it approximately 10–15 cm from your hair. When first using the spray, pump several times to prime it.
Do not use on a scalp with wounds or other abnormalities. Stop use and consult a dermatologist if irritation or other unusual reactions occur; continued use may worsen them. If the product gets into your eyes, rinse immediately.
