The Wow Brow gel is a buildable wax-gel hybrid that contains kaolin clay and fibers that attach to your natural brow hairs and enhances the look of your brows. I purchased the neutral brown shade and I love this brow gel. It’s so easy to use, the brush is small and it allows me to get close and really see where it needs to be applied. The shade matches my brow color almost exactly. My eyebrows are very sparse at the ends and this gel fills them in and they really look natural. I haven’t ever had any issues with it smudging after applying and it lasts me all day. It’s also super easy to remove with my makeup remover at night. Plus, you can’t beat the $5 price tag!
