Short hair is daring and edgy, but it can also look a bit serious if left super-straight. Soften up your short 'do by adding some sideswept curls--you'll give off a confident, sexy vibe that no man can resist.
Guys like hair that they can touch, so if you simply must do an updo, make sure it's one that doesn't look too done. We love Jennifer Lopez's loose, slightly rumpled hairstyle because it looks like morning-after hair--which will make him think of the bedroom activities you two could be doing.
If your outfit is daring and baring like Lea Michele's, keep your hair on the more modest side by sporting full, textured waves--they'll help tone down the boldness of your outfit so you look both sexy AND approachable.
The girl-next-door look is popular with guys for a reason--it gives off the impression that you're fun, easy-going and gorgeous to boot. Take a cue from Cameron Diaz, the ultimate GND, and rock a carefree, tousled hairstyle.
We love Milla Jovovich's half-up hairstyle because it's dressy enough to wear out on a date, but undone enough to look like you didn't spend a ton of time creating the style. The effortlessly gorgeous girlfriend--every guy's dream!
