INOA — S

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. S covers hair at or above shoulder length, about 65 minutes total — a quick, gentle color refresh for shorter cuts.
