LOreal Inoa is a permanent hair dye that replaces ammonia with a "minimal amount" of MEA and oil, hence the term ODS (Oil Delivery System) . The ingredients in Inoa preserve lipids, which are the natural conditioner of the hair, much better than ammonia can. This means that it is less corrosive than ammonia, preserving the integrity of the hair, resulting in less porosity, more shine, and better color retention.
Here are the positive and negative aspects of LOreal Inoa hair color:
Positive:
- Preserves lipids in the hair, resulting in less porosity, more shine, and better color retention.
- Provides optimal scalp comfort and results in 50% more shine than previously colored hair.
- Has a wide array of ammonia-free shades, with 116 available overall.
- Uses a new technology called Oil Delivery System that uses oil molecules to carefully open the hair shaft and soak in the dye.
Negative:
- Some users have reported that after a few applications of Inoa, their hair became dry, strangely kinky, and extremely brittle, with increased breakage.
- Although Inoa is marketed by LOreal as standing for "Innovative No-Ammonia," the products ingredients label shows that it contains ammonia hydroxide.
