Review (4/5): It works.
Depending on the saturation of your color it does the job well enough. I needed it to get out green. I'm on the 2nd treatment and will need one or two more. Green is the worst to get out it seems. But originally it was supposed to be a blue teal but it immediately went to green. I tried a lot of different things since the hair dressers near me have been booked solid for 2 months now.
So this stuff works, be patient, leave on more than 20min. The directions are sooo tiny. Mix both together, same amount each bottle. Mix into hair. Leave on 20 to 40minutes. It will probably burn ur scalp.
Also it smells like freaking chemicals and vomit. Have a strong stomach, the smell is aweful.
