IF YOU HAVE 5 MINUTES: CHLOË MORETZ
Pump up flat roots with some dry shampoo, then run a brush through your hair to spread out the product and add texture. Slide on a headband and back-comb hair a bit to emulate the actress's retro-chic style. Have a minute to spare? Go over the ends with a flatiron – a little twist at the tips adds even more '60s-inspired flair.
