Channel your inner rock chick with an edgy outfit and an effortless yet sexy 'do a la Jessica Alba. To need to get your waves even and prom-ish, random curls makes this laid-back look rock.

Get her look: Make a center part and wrap sections around the barrle of a curling iron away from your face. Rub a little wax between palms and scrunge.

Now here's a ponytail fit for a glam dinner date! Work height into the crown a la Kate Beckinsale for a polished look -- it's also flattering for most face shapes.

Get her look: Mist hair with a light hairspray and tease at the crown to add height, then use a brush to pull hair into a high ponytail and secure with an elastic.

Honey streaks like Leona Lewis' really warm up the complexion. Ask your stylist to add lighter streaks of highlight around the face-framing pieces which will brighten up your face.

Get her look: Make an off-center part and blow-dry hair straight using a paddle brush -- focus on getting your hair straight will give a better finish. Then flat-iron hair in sections.

If you notice, hair trends are moving toward the carefree look rather than perfectly coiffed updos -- like Anna Kendrick's organic casually-pulled-back updo.

Get her look: Randomly curl sections of hair with a curling iron to get Kendrick's wavy texture. Gather hair back at the nape and twist into a loose bun or French twist -- don't worry about the loose strands that fall out -- then bobby-pin in place.

Give a stick-straight 'do plenty of flirty movement at the ends a la Leighton Meester for a playful look that's still very elegant.

Get her look: Blow-dry hair straight with a paddle brush. To add the curls, divide hair ends into sections -- the smaller the sections, the tighter the curls -- and wrap around the barrel of a curling iron. Hold for a few seconds before releasing.
