Madge's loose waves are soft, touchable and utterly romantic. She also looks ten years younger than she actually is, which is never a bad thing.
Forget Jolie's dramatically-posed leg at the Oscars. Her hair doesn't so much scream "bombshell," as whisper it in a sultry voice.
Ponytails aren't just for the gym-bound. Vergara adds oomph by teasing at the crown and leaving a few loose strands framing her face.
The Up All Night star opts for a blowout with body. It's face-flattering, low-maintenance and looks great on just about everyone.
Witherspoon's choppy, layered cut looks like a grown-up version of a cool shag. The bangs are youthful, and the mega-watt smile, even better.
The Help actress nails the sexy-siren look with a teased half-updo and soft (but not too perfect) waves.
How to add va-va-voom to a classic bob, as exemplified by Byrne: Create a deep side part. It's unexpected and elegant.
Don't believe that short hair can be sexy? Rent Die Another Day and prepare to be disproved.
Fresh from the curling iron, hair can look too "done." Take a note from Kristen and brush out the corkscrews to create soft curls.
Grab your volumizer! Exuberant curls are easy to create (especially if you have natural waves) and oh-so-flirtatious. Hayek's dress doesn't hurt her vibe, either.
Take off the tiara, and what do you get? An etherial, date-night-ready side bun that can bring out the inner-romantic in everyone. Just keep it low to avoid the ballerina look.
If you have spare time and are especially dexterous with a curling iron, finger waves have a 50s pin-up vibe. Consider it retro sexy.
No time for a complicated look? Braid hair in the morning and let it loose after dark to get Kruger's dreamy waves.
Layers give life and bounce to what would otherwise be a stick-straight blowout. Plus, this lady snagged David Beckham. She's got to have a few tricks up her sleeve.
Pulling hair into a big, imperfect bun is a cinch. Just keep it polished by adding volume at the crown and placing the bun at the nape of the neck.
Traditional updos can wander into no-nonsense, office-ready territory. Let hair air-dry for extra texture and try an über-feminine deep side part.
Sims' half-updo gets a boost from thick, wavy layers. The "up" portion is smooth and pulled back a bit tighter, which (bonus!) has a mini-facelift effect.
Pinkett Smith balances a sleek ponytail with thick, blunt-cut bangs. The trick for making a ponytail work for a night out? Keep it low.
The red hair helps, but it's the subtle curls and long layers that are really giving Moore the sultry Jessica Rabbit vibe.
Just because it's a simple cut doesn't mean you can't still have fun with texture. Aim for a flapper-esque style with playful curls.
Now that you have 'dos perfect for Friday night, try these easy hair looks for the weekend.
