Ali Larter. Photo by Richie Buxo/SplashNewsOnline.comGET THE LOOK: Who knew today's most useful hair accessory would date back to the days of Jazzercise? While we're happy to leave bunchy socks and pink leotards in the past, we're all about protecting our blowout with a headband.
INSIDER TRICK: Stars like Ali Larter can keep their stands in mint condition even after a sweat session by simply protecting hair from frizz-inducing moisture. Before working out, pull your hair back in a ponytail with a cloth-covered elastic to avoid denting hair; wear a thick, stretchy headband along your hairline to absorb perspiration before it hits your locks.

Jessica Simpson. Photo by Humberto Carreno/StartraksGET THE LOOK: We've mastered the five-day blowout and week-long spray tan. But we still haven't nailed a lasting manicure! To make your top ten stay glossy all week like Jessica Simpson, swipe clear polish along the tip of each nail after you shower (when polish tends to soften and chip).
INSIDER TRICK: If you're prone to chipping (open soda cans with your nails, ladies?), try brands like Rimmel, which now offer polish with elasticity ingredients that make formulas more pliable and chip-resistant.
