Had a patch test a few weeks before the application.   I had told the stylist prior to her applying that I was allergic to any products with ammonia and she reassured me that there was no ammonia in Inoa.   Within five minutes of applying Inoa to my head, I could feel a very hot burning sensation on my head.   Had to have my head rinsed immediately in cold water, not a pleasant experience, and had to leave the salon with unstyled hair as stylist would not risk blow drying the hair in case of damage.  Researched this product on internet and discovered that this product does actually contain ammonia!  Totally agree with the comment above, avoid this product like the plague!!
