If — even after all of the prepping and styling from the previous two slides — your hair still looks flat after taking off your hat, flip your hair over and put your head under a bathroom hand dryer for a few seconds. Shake your hair out at the roots, but don’t brush it — that’ll just create more static. Flip right side up, and mist your roots with a bit of dry shampoo (try TRESemme Fresh Start Dry Shampoo, $5.49). “This will take any remaining moisture out of your hair,” says Irene.
