Works, but fades very quickly. [SEP] The pro...it does work, I loved the color I got, made my brows more defined. The only problem I had with Godefroy was how after a few washes of my face, it faded so fast. I would say it lasted two days tops, three days at max. I've gotten my brows tinted professionally which was about two months ago and I was sad to hear that the dye the professional used on me wouldn't last 2 weeks because she said her dye wasn't built for it, after that professional tint lasted longer than Godefroy, keep in mind I washed my face the same as when I tried Godefroy.
