INOA — L

INOA is L'Oréal's ammonia-free permanent color system — a gentler alternative to standard hair dye that processes at a lower temperature, leaving hair noticeably softer after coloring while still delivering full grey coverage. It's the salon's go-to recommendation for color-sensitive scalps or clients who dislike the smell and dryness of ammonia dye. L covers mid-back-to-waist length hair, about 2 hours total including the INOA processing time needed for full, even coverage.
