It's a '50s rockabilly-inspired updo for Dianna Agron at the Grammys, and we're loving the punk-meets-feminine vibe. The extra height at the crown also means this style works great on round and heart-shaped faces.

Get her look: Apply a strong-hold mousse to the roots on dry hair, and blow-dry, using hand to style and coax volume. Curl hair using a curling iron and bobby-pin sections in place from hairline to the crown. Pull the rest of the hair back into a chignon and secure with pins. Next, to create the pompadour effect, remove the pin curls and backcomb hair on top. Gently smooth over teased hair with brush then spritz with hairspray for hold.
