If you know you're going to sweat and don't want to ruin your style, Toth recommends creaseless hair ties like the Kitsch 8 Pack Hair Coils ($10) and what he calls the "pineapple" method. "Gather your hair into a pony tail on top of your head, bring it all the way through the hair coil once, and then bring it through the coil again but just half way — resulting in a faux-bun or pineapple shape," Toth said. "Bringing it up high on top of your head will keep your face framing tresses natural and full of body."
