I have been using this product for about two years now and I will tell you I have stopped permanently coloring my hair! Pro: This product is mixable. I use Golden Bars w/ Bombshell to give me a richer color and I get compliments all the time. I have shorter hair and I can create an umbre effect with this makin it as light or dark as I want. It's awesome! I do this probably once or twice a week in my normal hair routine after I put my leave it and style cream. It has to be applied to wet hair and if you don't want it to come off you have to let your hair dry completely. It's not going to last long so you have to keep it freshened but it's cheap enough and intense enough to do every morning. CONS: The color I like is hard to find. It is quite messy initially, until you get the hang of how much you need to achieve the color you want. It will get all under your nails so you have to wash your hands really thoroughly. Overall though, it is the best temporary color I have tried and I buy it over and over again!
