Angelina Jolie has a gently layered, below-the-shoulder style with cascading layers that flow perfectly. She had four inches trimmed to get this subtly layered, below-the-shoulder cut. Hairstylist David Babaii, who often works with the actress, says "it's a classic Vidal Sassoon 'round layer cut,' which creates cascading layers that reduce some of the weight in her hair so it flows better. The key is not to over-frame the face with too many choppy layers."

Her expert's styling secrets

1. Raise the volume

"Angelina's hair is so silky it needs product to give it just a bit of texture," Babaii says. "Wave spray does that, so long, straight hair gets an instant lift." He sprays the roots of damp hair, then blow-dries starting on top with a medium round brush, rolling sections away from the face.

2. Vary the curl

On top, he wraps 1- or 2-inch sections of hair around the barrel of a 1½-inch curling iron, hot-roller-style, curling hair away from the face. On the sides, he holds the iron vertically to wrap sections back, then slides the iron out and hair-clips the underside of each curl close to the scalp.

3. Give it a lift

Once the curl has cooled and he unwraps the clips, he uses a flat, firm-bristle toothbrush that has been spritzed with a little hairspray to back-comb the base of each section. He starts about 1 inch from the roots and brushes back toward the scalp. The friction builds fullness and hold.

4. Loosen the set

Babaii uses a boar-bristle paddle brush to gently brush through the hair. The bristles graze the top layers so you don't lose the lift at the base. He then shakes the hair out using his fingers. "This smooths the hair and opens it up but doesn't flatten it," Babaii explains.
