Great Product [SEP] The product does it job as long as you keep it on longer then mentioned in the instructions. I usually keep it on for 15-20 minutes on each eyebrow and I get fuller eyebrows for about a week. I also don't use the whole capsule, just 1/3 of each capsule for both of my eyebrows work. Using the whole capsule is just wasting product.The tint doesn't last long but it's better then filling in your eyebrow every morning. If you're looking for a more permanent tint, this product will not be it.
