The rock star coiffeur reveals how she does sexy, tousled tresses for famous hipster clients
SPECIALTY: "I try to make hair look like a stylist didn't touch it," says Fiona, the go-to girl for pretty hipsters such as Zooey Deschanel and Karen Elson. "So much Hollywood hair tends to be too precise—I like messing it up."
SECRET WEAPON: Fiona, who splits her time between San Francisco and New York City, is a big fan of hair powder: "It's great for shoots when models come in with too-clean hair. It's light, but when you spray it in the roots, it creates dense, buildable volume."
QUICK FIX: Want a flirty, tousled bedhead? Wash hair at night, let it air-dry for 15 minutes, pin it up in a loose bun, and go to sleep. "When you wake up, you'll have soft curls."
