Penelope Cruz's sleek tresses with center part
Center parts may look like they're trickier to pull off, but they're actually very flattering if you have a round or square face shape -- the middle part creates the illusion of length and looks great on face shapes that could use a little length. For hair as glossy as Penelope Cruz's, mist with shine spray and work it through using a boar-bristle brush.
Get her look: Create a middle part and apply heat protectant product before styling. Blow-dry hair straight with a large round brush then use a straightening iron to smooth strands.
