I have very fine sparse brows. I have always had trouble keeping them in place and perfect throughout the day. I do not agree with other reviews that once you apply, they stay put for the day. A simple thoughtless swipe to the forehead and half my brow can smudge off. The only product I have found to really stay put all day is the Wunderbrow. Not a green product but if your looking to have brows by the end of the day on a hot and sweaty day, then that is your product. For a day that I do not necessarily need stay put brows, I can go for this. Overall, for the smudge reason, I wouldn’t buy it again. For someone who is looking for just a little fill and definition, I would say this is a good clean option. I have brunette hair, this color Sharon was perfect for me. Not too red at all, just a dark shade of brown.
