Unless your face is very long or you have a large forehead, creating height at the crown is a great way to balance and flatter your features, as evidenced by the plethora of stars at the Oscars who used this styling technique.
And for once it's a technique that works just as well on short as well as long hair.
The key is to create lift from the beginning by applying gel to hair before drying for mould-ability and hold, then roller setting, which gives hair a foundation of thickness and shape upon which to build a style.
Once rollers are out, use a fine-tooth comb to backcomb the front section from behind, then dab a little gel on fingertips and use to mould the hair either back, a la Kate Winslet and Angelina Jolie or to the side like Evan Rachel Wood and Natalie Portman.
Always finish with lots of hairspray for shine and to make sure the shape doesn't deflate like a soufflé.
