Strong Brows Think Brooke Shields next time you tweeze your brows. Pull out only the strays that fall well outside your brow line, and then get to work filling with brow pencil and powder. The pencil is for bald spots: Use short, light strokes to draw in missing hairs. The powder is to make brows look thicker: Load some on an angled brush and gently stroke through the entire brow. Finish by running a spooley brush through to blend all your handiwork.
