Rated 5 out of 5 by from Gray Coverage That Delivers Here’s a clean, professional SalonCentric Review Crew style write-up you can copy/paste: ⸻ I recently used L’Oréal INOA permanent color in levels 7 Natural and 6 Natural on two clients with 100% gray coverage, and I’m really happy with the results. I waited to review until I could test it on full gray clients because gray coverage is where it truly counts. While the formula does appear deeper and richer during processing, once rinsed and dried it settles beautifully into the true level and blends evenly with the natural hair. The coverage was full, soft, and natural looking with no hollow or translucent areas. Overall, a reliable choice for stylists who want ammonia-free color with consistent gray coverage and a smooth finish.

Rated 5 out of 5 by from Absolutely love this color line! The coverage is super opaque without feeling harsh at all, and the finish is beautiful—so glossy and healthy-looking. I love that it’s ammonia-free, so there’s no strong smell and it’s way gentler on the hair and scalp. The results are rich, vibrant, and long-lasting. Definitely one of my new go-to color lines!

Rated 5 out of 5 by from Surprising product!! I received this to review from BzzAgent..since it is a gentler formula, it works well on sensitive scalps. It gave a nice shine to the hair and a nice smell..pretty good coverage for low/no ammonia. Definitely recommend!!
