I am obsessed with this product. I have really light body hair naturally, but dark brown hair. So I always struggled with having to constantly fill in my eyebrows, even on no makeup days. I tried this for the first time tonight and once it is wiped off it looks so natural and beautiful. You are also able to shape your brow with this product instead of just dying the brow hairs. My eyebrows look like I filled them in but in reality it is just this product. Since I just used it I am not sure how long it lasts but I know henna does last long so I am sure it will last a long time. This product also comes with enough to use more than once, so it can be touched up if it begins to fade.
