Mary J. Blige's shag is a good choice for layered, medium length hair. What to do: 1. Apply a straightening cream and blow dry hair with a round brush, flipping your ends out. 2. Follow up with a flat iron to further straighten and flip. 3. Apply styling wax to your ends to keep them from falling limp and to get that piece-y texture.

Mariska Hargitay's style is a perfect choice for fine, straight hair. What to do:1. This look is all about the cut, so take this picture to your stylist and ask for a short, layered bob with long, sideswept bangs. 2. To do this 'do, use mousse at the roots of your hair and blow dry hair up at the roots to get some volume, then style straight.3. Fix your bangs by holding them to one side, between your second and third fingers, as you dry.4. For the finishing touch, put a little wax on your fingertips and piece out the ends of your hair. Keep the wax just on the ends or your style will fall flat.

Mandy Moore's adorable razored, short 'do is chic and sexy. Steal her style: 1. With a short cut, it's especially important that you use a styling mousse on wet hair, so that the look doesn't go flat. Working a dollop of mousse through hair before your blow dry will add volume, especially to the top. 2. Part hair to the side. Using a small round brush, blow dry small sections of the front and side under (pull brush through hair with brush under hair). For the back of hair, blow dry with brush on top of hair, which will help add volume and achieve the piecy look at the ends.3. To finish the look, use hair wax to arrange pieces of bangs, and to sculpt ends of hair in back. Lock in place with a light-hold hairspray.

Brittany Murphy's shaggy cut is fun, funky and most importantly fuss-free for straight hair. Get the look: 1. Start by applying a small dollop of gel throughout hair with your fingers. Don't get crazy with the gel though, less is more here for short layers.2. Blow dry hair upside down using your hands to tousle strands gently as you dry. 3. Flip head back upright and lift random strands up towards the ceiling while directing heat up the root to build volume. 4. Once hair is dry apply some pomade or wax and loosely twist and pinch ends to create piecey wisps.
