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 minutes on each eyebrow and i get fuller eyebrows for about a week i also do not use the whole capsule just of each capsule for both of my eyebrows work using the whole capsule is just wasting productthe tint does not last long but it is better then filling in your eyebrow every morning if you are looking for a more permanent tint this product will not be it
