Left my hair soft and undamaged
This was a great experience. I used about half of the containers since my hair is so short. I'm including photos of my hair before, faded blue green, and after,  honey blonde and orange (which is about what I bleached it to before putting the blue and green in) my roots are not affected and my hair is so soft. I kept expecting the horrible oder that people mentioned but honestly this wasn't that bad. If you've permed your hair or been to a nail salon this smell should be tolerable.
