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.
