I have dyed my hair twice before, and both times it was a medium auburn color similar to Revlon Colorsilk #42. This hair dye, however, has to be my favorite so far. The color guide on the box matched my final color almost perfectly, no surprises and no need to touch it up. The Revlon Colorsilk line claims to "Leave hair in better condition than before you colored, " while I'm not sure about that claim it certainly didn't do any damage to my hair. The dye itself left my hair feeling rough and dry, but the after coloring conditioner brought it back to its normal silky condition.
Colorsilk is also ammonia free, which makes it less damaging and fine for repeated use. It unfortunately still has a strong odor, and I would recommend that users dye their hair in a well ventilated room. I had a friend apply the dye for me, and it was a little messier than my usual brand. Overall though I was very satisfied with Revlon's Colorsilk line of hair dye and I plan to use it again.
