We set out to prove how important eyebrows really are -- by replacing the worst celebrity arches with the best in Hollywood

You've heard it a million times: Great eyebrows can completely transform your look. But just in case you had any doubts, we did some instant celebrity eyebrow makeovers to show just how dramatic the change can be. 

First, we sat down with eyebrow expert and owner of New York City's Boom Boom Brow Bar, Malynda Vigliotti, to choose the best arches in thick, medium, and thin shapes. Then, we took stars with just plain horrible brows and -- with a little Photoshop magic -- gave them a better set. The difference is remarkable. Even women who were beautiful to begin with look noticeably prettier with a new pair of face-framers. 


Disclaimer: Although our brow makeovers are an upgrade, some of them look a little wonky since they're not the celebrities actual brows.' "There isn't one exact template or stencil," says Vigliotti. "Everyone's face is so different -- you need to work with what you've got." While she'd love to get her tweezers on these stars, the visuals are also gratifying. "It demonstrates how important brow shape really is," she says. Check out these celebs' new brows and who knows, maybe you'll get inspired to do your own brow revamp too.
