12 Super Size Velco Hair Rollers, $17

Velcro Rollers: "You get that great modern volume," Riawna says of using Velcro rollers. "But you have to make sure hair is 100% dry before you put them in. Also, everyone wants to pull hair straight up and roll their hair down. But that's not the best for volume. Instead, pulling sections straight forward, 90 degrees, will give the biggest bounce and lift." Even if you don't have time for a full head, "put one Velcro roller in the top crown and one on each side of that" for an extra boost.
