I started using the previous version of this hair dye two years ago and I was very satisfied. For a while last year, I started using a different brand and regretted it. When I bought this one again, it had the new version which, personally, I find even better than the previous one. The color I use is 10.17 and out of all the ones I've tried so far, it is the gentlest on my skin and gives me the best result. The color takes a while to fade and it looks natural even though it is several shades away from my natural color (I am light brown/dark blonde). I have also noticed that if I use the shampoo specifically, as well as the hair cream from this line, after dyeing, my hair takes noticeably longer to fade and yellow, which is why I now occasionally use silver. This shampoo really enhances this color. Of course, dyeing your hair at home is not the same as the work of a professional, but this dye is very reliable, especially with the 1+1 gift offers that are available.
