This year at the Cannes Film Festival, several A-list stunners sported gorgeous gowns and glowing faces and, here's a twist, two distinctly different hairstyles -- one night they wore updos (like these simple-yet-sexy styles) the next, they wore hair down (similar to these natural looks).

Which do you prefer? Think some of them should've stuck with the updos? Or do you like their hair better long and loose?

Cast your vote. (And, while you're at it, what do you think of these dramatic celeb hair makeovers?)

(Psst, want a chuckle? Check out this gallery of outrageous celeb updos and the hands-down WORST hair trends of all time.)
