In 2005, most of our brows were probably similar to Conrad's: The too-skinny-tadpole look was a trademark of the times. But she's since demonstrated that it's possible to bounce back, and now her fuller arches are among the best we've seen.
Still struggling with sparse brows? Try this regimen:
1. Retire the tweezers. It takes three to four months to see a real change, and up to a year for brows to grow back entirely.
2. Mind the gaps. Fill in sparse areas with a brow pencil (eyeliners are too creamy and heavily pigmented). Go one to two shades lighter than your hair if you're a brunette, or try taupe if you're blonde.
3. Shape up. Define the arch (the brow's highest point, just beyond the iris as you look ahead) by yanking a few hairs below it. Eyebrows that fall short look aging, since the ends naturally thin as we get older.
