Graceful, loose updo twists like Jennifer Lopez's look especially flattering on heart-shaped faces and show off those high cheekbones.

Get her look: Curl hair using a large-barrel curling iron, then gently brush hair to loosen curls. Tease hair and divide into haphazard sections, lightly twist each section and pin up with bobby pins. Repeat, pinning each section at the same mid-area at the back of the head. Finish with hairspray for extra staying power.

Stick straight hair may be chic, but it's thick, luscious waves that command the red carpet. Case in point: Jennifer Lopez, who is the queen of glam with her crowing glory of full-bodied waves at "The Curious Case of Benjamin Button" premiere in Los Angeles.

Get her look: Apply a wave-defining product to towel-dried hair. To fight flatness, blow-dry hair with a large round brush, lifting the roots and pulling hair in the opposite direction from the way it grows. As you dry section by section, wrap each around a Velcro roller and roll just to eye level, so the top stays smooth. Direct the dryer at each roller for 10 seconds. Let cool, gently unwind and mist with a light-hold hairspray.
