Unfortunately, the INOA line is packed with ammonia. If any salon professional actually read the ingredients label for INOA they would see that "Ammonia Hydroxide" is listed on the pre and post shampoo in large amounts. Then, simply look up "Ammonia Hydroxide" in Google or Wikipedia to find that it is simply ammonia and water. Pretty sad how easy it is for a big company like L'Oreal to take advantage of unwitting hairdressers isn't it? Try Organic Color Systems or Henna instead for something that is truly ammonia free.
