When I was obsessed with having fuller brows, this was my go-to. I got this in the color Grey Brown. I was worried at first that this might somehow turn grey, but it actually is just a cool toned brown color like I had hoped. I usually put this on at night before I go to sleep (avoid using moisturizer and serums around the area), then I peel it off in the morning. Sometimes I use some pencil to fill in the brows were I may have missed a spot but otherwise, my brows are done! It's such a great time saver in the morning.
