Review: So Happy With The Results! - I've always had very dark brown hair, dark enough to where it can be considered black. I can't do anything with it in regards to coloring it, without needing to bleach it first. I have searched high and low for the perfect product, that would still show up in my hair without me bleaching it, as I don't want to end up destroying it. When I found this product, I wasn't sure what to expect, as everything else always gave me the same results; black hair that appeared darker. I had hoped that it would do some good, considering it is a Korean brand product, who, naturally, have dark hair like mine. I was beyond excited to see that this dye ACTUALLY showed up in my hair! It did exactly what I had been hoping for, giving my hair the best blue shine! While the results were not what were on the front of the box, the color was still a beautiful dark blue, that everyone was able to see! Not only that, but after I had rinsed the excess dye out of my hair, without shampooing or conditioning, my hair still remained soft and smelled wonderful after I dried it! The color, while somewhat faded, still remains in my hair, after several washes (I dyed it about 3 weeks ago). I would 100% buy this product again, especially for the price!
Review: Crap!! - If you want to waste your time and money, this is the product for you!! Looked great after the first wash. After that it washed out after every wash. Only lasted about a week. I give it zero stars. The only reason I gave it one was because I had to put a star to submit my review. Wasted my time dying my hair, which is down past my waste. So you know it took awhile to dye.
