I'm not sure...this wasn't color though, it was bleach. I had to wash it. The products I used made my hair feel icky (I tried out some products my stylist had). There would have been no day 2 or day 3 hair with it.
Also, I'd like to add that I did not like the GF 2n1. It certainly got rid of cones I'm sure, and all the natural oils and moisture in my hair as well.
