INOA Hair Color Ingredients

Please Refer to the following UPDATED article:

Many people have called and asked us about INOA, L’Oreal’s ammonia-free hair color, and it’s ingredients. As stated in our posts, we are disappointed that L’Oreal would chose to market an ammonia-free hair color line which does in fact contain plenty of ammonia.

Aside from being alerted to this fact by our clients and consultants, we were intrigued by the increasingly heightened level of interest regarding INOA’s surrounding the ingredients of this product. We decided to inquire about the ingredients of the product and we were somewhat surprised at what we found and now understand better what the curiosity is all about. Here is what we found:




Skin Deep Rating

Aqua Water A safe primary ingredient. Low Hazard 0
Ethanolamine Used as a pH Adjusters, generally considered to be safe in cosmetics at low concentrations. Ingredients are required by law to be listed in descending order of concentration. The fact that Ethanolamine is listed as the second highest concentrated ingredient in INOA may be a bit of a concern. Moderate Hazard 4-6
Alcohol Denatured Ethanol that has additives to make it more poisonous or unpalatable. Used as a viscosity controller. Generally a safe ingredient. low Hazard – 2
Propylene Glycol Viscosity controlling agent also used for skin or scalp conditioning. Generally considered to be a safe ingredient. However, there remains some controversy regarding this ingredient seemingly because it is also used in anti-freeze products (as is water). Moderate Hazard – 3
Dipropylene Glycol Viscosity controlling agent. Generally considered to be a safe ingredient.

Low Hazard 1
Hexylene Glycol Used as a solvent, surfactant, or emulsifying agent. Generally considered safe but represents a strong skin irritant. Moderate Risk 4
Hydroxyethylcellulose Emulsion Stabalizer Generally considered to be safe. Low Hazard 0
Resorcinol Synthetic dye used as hair colorant This is a very dangerous ingredient and there are much safer alternatives like 4-Chlororesorcino. It seems odd that a company would choose to use resorcinol when a much safer, and arguably more effective, alternative exists. The only conclusion might be to save costs. High Hazard 9
p-Aminophenol Hair colorant agent derived from coal tar. Generally considered to be safe provided use and concentration restrictions. High Hazard 8
Toluene 2,5 Diamine Aromatic amine This is a dangerous ingredient that has been restricted for use in cosmetics in the Cosmetic Ingredient Review Assessments and has been linked to certain kinds of cancers and reproductive disorders. High Hazard 7
2 Methylresorcinol Hair colorent and aromatic anime. A low toxicity ingredient that has demonstrated some links to temporary skin irritation in certain concentration levels. Generally considered safe. Low Hazard 2
Sodium Metabisulfate Preservative A moderately dangerous preservative that is a known human immune system toxicant. Moderate Hazard 5

INOA Hair Color Ingredients Conclusion

Most (almost 60%) of the ingredients of INOA’s base which we evaluated had a skin deep rating of “moderate” or “high”. This is compared to about 20% of Organic Color Systems. Further, although we applaud L’Oreal’s efforts in removing ammonia from their hair color, we do not understand why they would use resorcinol and such a severe concentration of ethanolamine in their hair color and keep ammonia (ammonia hydroxide) in their non-ammonia line.

    Hi there,
    I have been having my hair dyed with Inoa for 14 months. My hair was colored dark brown and I had requested taking the color down to a lighter richer brown. I was advised to use the ammonia free Inoa color and started to have my hair dyed a lighter color at the roots. 14 months later, I am noticing my roots are sparser and my scalp more prominent. Today I have decided to make an appointment in another salon with an old friend who has treated my hair in the past. I am extremely worried and growing depressed.

    Marty, Although INOA advertises as ammonia-free, they do actually contain ammonia in their line. Also, the plastics in the styling products you are using is likely clogging your hair follicles and and severely hindering new hair growth. Please consider using a salon that uses Organic Color Systems and try our Plastic-Free hair style line called Organic Control System. This will give you hair the best chances for new hair growth, naturally.

    Don’t believe EVERYTHING you read Mary! Of course Organic Color Systems is going to talk bad about a competitive product. If their product was so great, they wouldn’t feel the need to bad mouth another line! Ask your colorist why she made the choice to use INOA, it’s probably because she wanted to offer a premium, ammonia free, odor free color line that is safe for her and her guests.

    Well, shoot. I’m always very careful to check ingredients. That’s very worrisome. Really disappointed.
