Recreate Dianna Agron's red-carpet coif with this step-by-step guide, courtesy of celebrity stylist Giannandrea:

"My inspiration for Dianna for the 'Glee: The 3D Concert Movie' premiere was ‘British rocker/sexy/messy. I started with wet hair and razor cut her bob into a more playful ‘Shab.’ This is what I call this hair cut! This cut is a progression of the bob but it has more life and does much more when you style it. Next, I added Kerastase Volume Active Mousse to the whole head and roots. I blow dried the hair - just air, no brushing - until the hair was completely dry. I then brushed it with a large round Mason Pearson brush. I use a brush just for the bangs and blow it straight. The other part of the head was just scrunched and bent with my hands. I then used Klorane Dry Shampoo Spray on the whole roots and top of the head, and back brushed the top part of the head. Finally, I set hair into place with L’Oreal Elnett Hair Spray.”
