Behind The Scenes with Sandra Oh

Sandra Oh showed up at L.A.'s Quixote Studio wearing a major, chunky skull ring that drew oohs and aahs. Her secret: It's actually a $10 novelty Secret Santa gift from Grey's Anatomy costar Justin Chambers. The studio shook with techno and hard rock until Oh requested Björk-all she needed to return to her ballet roots and dance for the camera. The shoot was so fun that Oh stayed behind afterward to hang and have a beer with the crew. Then on to a fitting for her molten--silver Golden Globes dress.

Celebrity-hair god CAMPBELL MCAULEY gives us the lowdown

He's the affable Aussie who tends to Hollywood's alpha locks-and created Oh's hot cover-girl look.

WHAT WAS THE CHALLENGE?

MCAULEY: Sandra has great, thick hair, so I wanted to give it vibrancy and sex appeal and go for lovely and luscious. We started out tamer, but the more I shook it out, the stronger the images got-and Sandra can go there. She's such a grounded, true person; she really let go.

IS THIS A WIDER TREND WE CAN ALL HAVE FUN WITH?

MCAULEY: Yes, we're starting to see a fuller look. I'm loving it-it holds more life. Straight hair is so done; with fullness you can let it breathe a little.

WHAT'S THE MAGIC TRICK?

MCAULEY: A large curling iron, a mixture of hairspray and moisture cream-and girls, never use a brush. You scrunch dry and finger-shake the hair, then twist the curl with the iron in a messy way. Apply hair-spray while upside down, then throw your hair back.
