PROFESSIONAL USE: Apply throughout the hair and let it sit until you reach the desired tone. Rinse. If applied immediately after highlights, start the application from the nape of the neck working through the length of the hair, massaging section by section, until you reach the top of the head and rinse. ATTENTION: Highly porous hair might absorb excess pigmentation.
HOME CARE: Do NOT apply on the same day of highlights (Highly porous hair might absorb excess pigmentation). Use only as maintenance to keep desired color. On the first application, let it sit for 30 SECONDS to 1 MINUTE and increase processing time accordingly in the following applications. A maximum processing time of 5 MINUTES is recommended.
