Well color oops worked great for my hair, it too the pink out after i had bleached my hair from red. the way that hair dye works is that when you put it in the molecules are small, thats why you have to leave it in, so the molecules become too big to wash out. what color oops does is make the molecules small again so all you have to do is wash it out. directly after i put the color oops in and let it sit for the right amount of time, i shampood it about 10 times back to back, you can let your hair dry in between and you have to make sure to shampoo all of the color out, o it wont work, so 10 times is a good number. I would let my hair rest for a day in between dying because all the shampooing makes the hair kind of rough, but nothing a deep conditioning can’t fix. it’s a great product though.
