I have used this in the past and its seriously not worth it. Let me add that i have not only used this once, but have given it multiple opportunities!! The bottle is pretty big so you think you are getting a pretty good deal, but you are not! You basically put it in your hair, let it sit, then rinse it out without even the slightest tint of color remaining. Not to mention it takes over half of the bottle to cover a single head. If you ask me, it is basically colored water that does not do a darn thing. I would recommend that you all save yourselves the time, and save yourselves the money! I ask you that you please take this review into consideration before you buy this product. Thank you for reading!
