Fake hot-roller waves in 25 min: “Forget the hair underneath—just pay attention to the parts that show,” says Kevin Ryan. Blow-dry while combing hair with your fingers, pull bottom layers into a ponytail to get them out of the way and blow out just the top and front sections with a round brush. While hair is still warm, wrap 2" chunks of hair around large Velcro rollers, 5 or so. Mist w/ hairspray. Hang for 10 min—remove rollers.
