Get Thicker Brows

Fill in sparse brows with a powder, pencil, or gel. Go two shades lighter than your hair color if you’re brunette, two shades darker if you have pale blonde or silver hair. When in doubt, taupe works on almost everyone. Use tiny strokes over your arches and blend with a brow brush to remove extra color. 

Skip the Stencils

The perfect brow is based on your unique bone structure. Using a stencil to draw on your brows may seem like it takes the guesswork out of shaping. But you may not like the results. A stenciled brow that’s just a little bit off can make you look angry, surprised, older, or even lopsided.  No thanks! Better to work with your natural brow shape.

Make Brows Match Your Hair

If you make a dramatic hair color change, your brows should change, too. You’ll want to see a professional colorist. Don’t dye your brows at home, even if you have a really steady hand. Need a quick fix? Blend mascara or concealer into your brows to instantly go darker or lighter.

Get The Natural Look

Actress Camilla Belle proves you don’t need whip-thin, sculpted brows to look modern. To get yours as lush as possible, don’t pluck a single hair for three months. Then have them shaped professionally or pluck only the most obvious strays yourself. Use a brow filler for better definition.

Use the Right Tweezers

Rounded tip or pointy? Experts like a pointed, slanted tip, especially if you haven’t plucked before. You can hold that shape easily and grab longer hairs. For those short, stubborn hairs, turn the tweezer at an angle and pull from the pointed edge.
