Get the Look: Rose Byrne at the 2012 SAG Awards.

Rose Byrne revealed a whole new look on the red carpet tonight. Rose's stylist and John Frieda International Creative Consultant Harry Josh says that her new look is "70's inspired with a modern twist. Think Michelle Pfeiffer in Scarface meets a modern day Anna Wintour."

Here is how Harry styled Rose's new 70's inpsired bob to go with her chic white Elie Saab jumpsuit for the red carpet:

Step 1 - Saturate the Roots with a Volumizer "I needed to get a lot of lift at the roots. Without that, the look would just fall flat," says Harry. On wet hair, he applied tons of John Frieda Full Repair Root Lift Foam ($6.99) which not only gave him the weightless lift that he needed, but also helped to protect against damage caused by heat styling.

Step 2 - Protect the Ends
Harry applied the Full Repair Perfect Ends Deep Infusion ($9.99) to smooth the ends and make sure they looked healthy and groomed since her new cut is so blunt.

Step 3 - Blow Dry with a Round Brush
Section by section, Harry used a natural bristle brush and angled the blow dryer down to get maximum shine.

Step 4 - Place Velco Rollers at the Crown
Harry used the rollers to lock in the volume.

"It's the epitome of chic, just like Rose." - Harry Josh
