GET THE LOOK: Here’s fabulous Jessica Alba at Sundance 2010 for her Premiere of ‘The Killer Inside Me’. Frederic Fekkai Celebrity Stylist Renato Campora created Jessica’s hairstyle. The Look & Inspiration: a modern undone look for an evening night out, using a headband to define the look.

Here’s How to get Jessica Alba’s hairstyle at Sundance 2010:

On wet hair, Campora used Fekkai Coiff  Strong Hold Volume Mousse. He blow dried the hair using his fingers in order to create texture. Next, he wrapped hair around a hair stick to the back of the head and locked it into place. Campora then diffused the hair at the roots.

After hair sat for ten minutes, he took the stick out and applied Fekkai Au Naturel Dry Shampoo. With his fingers, Campora created even more texture at the roots by tousling the hair. Campora secured a messy bun using bobby pins to the back of the head and added an elastic headband to give a fresh, defined look. Finally, he sprayed Fekkai Sheer Hold Hairspray throughout the hair to set the style.
