i've been in Paris for a month and bought this hair color. this is BY FAR the BEST home hair color i've ever tried. Color adheres to my hair very well and I love the shade for my dark brown hair . As with most hair colors, i find i have to go a shade lighter otherwise it turns out too dark. I used #5 light chestnut (chatain clair). Cost was 13 euro which at current exchange rate is roughly $16. I also feel like it is less damaging than other brands (loreal, clairol, garneir, etc)
I love this so much i'm buying several to take home with me!
The name of this is Phyto Color
I purchased a couple boxes of this in Paris, and it's a better home color than most. I used a dark brown shade, and it was natural looking and didn't damage my hair more than anything else. It also came with samples of a treatment oil.
