How to Use
Follow all pack steps before preparing the mixture, including an allergy test at the specified time before every use. Wear gloves, mix this version's contents as the label shows, and apply in the printed order and waiting time. Rinse as directed and do not retain mixed dye leftovers.
4.0 identifies the version more precisely than Brown alone. Check matching shade numbers between packaging and components before starting, and do not mix shades or oxidants outside the pack system.
