Glossier Boy Brow (£14) is the brand's OG eyebrow product — a pigmented brow gel that deposits colour (as long as you don't select the transparent shade) and makes it easy to maneuver the hair into the direction you want to place them in. The short spoolie allows you to comb each hair and add "fluff" and volume for a 3D effect.
The benefit of using Boy Brow is its ability to tame any hairs that you feel might be going rogue, but it is difficult to further define its shape. The new product picks up the slack of the OG, and together they are a dynamite team.
