Overall, I am quite pleased with this. My natural hair is a light brown/dull dirty blonde, and I used the medium reddish brown colour. The dying process was quite easy; the formula was completely drip free and an adequate amount was provided for my very long, thick, curly hair. However, it had a very strong unpleasant chemically smell. Upon rinsing it out, my hair felt pleasantly smoothed which was a nice surprise. The colour turned out very beautiful, quite similar to the colour on the box. I have washed my hair twice, and very small amounts come out in the shower but no noticeable fading of the colour yet. Mind you, I use an extremely small amount of shampoo(my hair is generally dry). The included conditioner also works great, even though my hair is picky about conditioner. I’m still a tad bit worried about fading, but overall I’m very happy with this product and will most likely purchase it again.
