Who knew haphazard hair could look so chic? We are used to seeing these "bedhead" styles splashed across celebrity weeklies when stars get caught on a Starbucks run by the paparazzi, but these relaxed 'dos are making their way out of bed and onto the red carpet. From movie premiers to award shows, short to long hair, these playful textured looks are making big waves in Hollywood.

Celebrities like Sienna Miller and Kristen Stewart have been frequent displayers of this carefree look. But other celebs like Jennifer Garner, who is known for her usually polished style, has given this textured look a go and even Victoria Beckham has abandoned her "Posh" look for a more tousled one lately.

While these hairstyles are slightly more dressed up for a night out, they still give off an easy-going, I'm-not-obsessed-with-being-perfect look. That said, it may seem as though these celebs just rolled off the pillow, but in reality they did spend some time primping. That is why we spoke with Jillian Halouska of Warren Tricomi Salon in New York -- to get the scoop on how we mortals can get this perfectly messy, textured hair.

Long, wavy hair, like Miller's and Fergie's, is perfect for creating this laid-back style. The middle part also helps create a '70s feel, a decade known for its relaxed, anything-goes attitude. To get the look, start with damp hair. Run a quarter size of mousse, like Got 2b Kinky Curling Mousse, $6.29 through your strands, from root to tip. Then apply a dab of styling cream just on your ends. Flip your head upside down and blow-dry just the roots with your fingers. When your roots are completely dry, flip up and part your hair down the middle. Continue drying the ends with a round brush, rolling the hair around the brush. Finish by wrapping a few random, large sections of hair around a curling iron (try Conair Infiniti Curling Iron, $24.99). Just wrap the middle of the section. "Don't curl the ends or tuck them in. They need to stick out and look schlepped around," says Halouska.

Beckham proves you don't need a ton of hair to try this trend. Her super short, textured style is perfect for a "messy" look because it's effortless since there's so little to work with. To recreate the style, Halouska recommends rubbing a small amount of matte pomade like Redken Rewind 06 Pliable Styling Paste, $17.99 between your palms to warm it up then running it through your hair, lifting it at the roots. Twist a couple of random pieces of hair at your crown to add the funky texture.

This muddled look is a great alternative to perfect ringlets, especially for gals, like Reaser, with naturally thick, curly and often frizzy short hair. The key to pulling off this look is to "avoid frizz while still looking textured," says Halouska. A good way to avoid frizz? Diffuse hair perfectly. Follow this step-by-step guide for help. After diffusing, create an imperfect part and spritz with a hairspray (try TreSemme Curl Locking Extra Hold Styling Spray, $4.50)

It's a bit trickier to create tousled hair that lasts in straight hair like Garner's, so follow these steps: The night before you want to achieve the look, make one big, tight braid starting at the top of your head and ending at the tips (do this after showering, when hair is still wet) and secure with an elastic. If you have bangs, leave them out. Then, in the morning, undo your dry braid and finger comb your hair to loosen. Holouska recommends spraying your bangs with a dry shampoo (try Rene Furterer Naturia Dry Shampoo, $21) give them a messier look. Finish the style with soft-hold hairspray like Dove Flexible Hold Hairspray, $4.60.
