Scarlett Johansson : super sleek side parted hair.
Taylor Swift: same as Scarlett's.
I actually don't know this one but I love the braid.
Scarlett Johansson. Again. Really natural, flowy with soft waves.
Leona Lewis. Love the nerd-chic look complete with glasses.
Jessica Biel: glossy, middle-parted hair. Pretty and always in style.
