I don't know about instant conditioners, but I've found that using hairspray sets the color nicely. I have dark brown hair and I purchased this in blue. It goes on easily, and it comes of just as easily. I personally like this because you can just shake it out if you mess up. Once you have the color where you want it, spray it with some hair spray (I use Herbal Essance Body Envy) and the color will stay all day. I've even had it last overnight and into the next morning with a hair spray setting.
