Revamp Your Look For Fall With These Fresh Hairstyle Ideas

Straight-haired girls: if you're wary of trying a traditional bob because you think it will look too severe on you, ask for a cut like Olivia Munn's. Asking your stylist for softness and structure will give the style movement, avoiding the dreaded helmet-hair look.

"Cropping [straight] texture will allow for more lift and movement, but the length and structure keep this cut as professional as you need," explained Reyman.

"It's a power cut, not a cower cut," he added.

If your hair is ultrafine, adding texturizing products — Reyman likes Aveda's Phomollient Styling Foam ($20) — is a must. They'll keep your look from falling flat.
