I have had similar bad experiences with the product. It does not cover grey, it fades after a week, it leaves the hair dry, brittle, and damaged after the first wash following the color treatment, and other products in the line, such as the shampoo and the oil that is mixed with the color, contains high levels of ammonia. I have had two clients that have developed horrible irritations and reactions to this color who told me they were sensitive to ammonia. I feel horrible.

This is one of those very bad products that is being shamelessly marketed by a pretty good company. I wouldn't throw all L'Oreal products out the door, but if you're using INOA you've made a horrible mistake.
