Why Guys Love It: Nikki Reed's bun looks simple and elegant yet still touchable. The hair that falls into her face prevents the updo from looking too severe. "Men couldn't care less if your strands are perfectly styled and neat. In fact, he might like you more with some wildness or bedhead, since it shows you're carefree and relaxed," says Fisher.
How to Get It: Make a low side ponytail, leaving a few pieces loose around your face. Twist the length of your ponytail, and wrap it into a figure-eight shape — smoosh it up against your scalp, and tuck the ends into the loop. Insert a few hairpins or tiny barrettes to lock it all in place. Finish with a mist of light-weight hair spray that'll give you extra hold minus any stickiness, like Paul Mitchell Worked Up, $15.
Sexy Side Pony
Why Guys Love It: "An assymetrical updo is universally flattering for all face shapes because nobody's features are perfectly aligned," says NYC celeb stylist Nathaniel Hawkins. That means a side pony is an easy way to make sure no one notices your flaws. America Ferrera's look is soft without looking sloppy or overdone.
How to Get It: Rub on a smoothing gel like L'Oreal Professional Texture Expert Gelee Riche, $20 through wet strands. Blow-dry hair over to one side to create hold. Then use your fingers to gather hair low under the ear and secure with an elastic band (keep it loose so the bun doesn’t look too prissy).
Schoolgirl Pony
Why Guys Love It: Play up your naughty cheerleader with Michelle Trachtenberg's easy updo. The look works best when the pony is a bit relaxed. "Loose hair with tons of movement is such a hot look," says Tresemme stylist Nathaniel Hawkins.
How to Get It : Set hair with styling cream then curl with a medium barrel iron from ears to ends. Using a fine-tooth comb, sweep hair up, secure it directly above your crown, then wrap a few strands around the elastic. Mist on hair spray for hold.
