INOA — M

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. M is for shoulder-to-mid-back length hair, roughly 90 minutes total to fully saturate the added length with the ammonia-free formula.
