Subtle, understated curls will allow the hat to take center focus but still create a put-together look, says Mika Fowler, a Beverly Hills-based hairstylist who works with Olivia Munn, Emma Roberts, and Annalyne McCord. “It also diminishes the volume that is taken up from the floppy hat by not creating any bulk.” Here's her step-by-step:
1. Work about a dime-sized amount of a light serum through damp or dry hair for shine. Fowler recommends Joico's Reconstructive Color Therapy Oil.
2. Using a 1-inch curling iron, curl the hair in equal sections, stopping about halfway up since your hat will cover the top of your hair.
3. As each curl falls, lightly spritz with hairspray to keep the curl locked in without a sticky feeling.
