Sure, it helps if you're starting off with hair like Blake's. But Here's a breakdown of how you can emulate this celebrity hairstyle:

1. Blow-dry hair with a diffuser and Bumble & Bumble Surf Spray.
2. Curl hair with 2-inch curling iron. Pull out curls with fingers.
3. Select random front pieces to twist and braid on each side of the head.
4. Loosely pin back twists and braids with bobby pins. Spray with Bed Head Spray-on Shine and Bed Head Master Piece Spray all over.
