Sedu, Formal Hairstyles

Megan Fox's style with a side part is a perfect way to show off super-straight hair. Get her look: 1. Start by combing a straightening serum through your hair. 2. Make a straight side part.3. Using a flat brush, blow dry your hair straight, aiming the nozzle of the blow dryer down your hair length. 4. Heat up a straightening iron and slide it from roots to tips5. Put a few drops of shine serum in the palms of your hands, massage palms together and smooth over your hair from the part down.

Liv Tyler's easy updo works best on straight, medium to long hair with long bangs. What to do: 1. Begin with perfectly straight hair (do a run-through with a flat iron if you must). Rub some shine serum between your hands and smooth over hair to get extra shine.2. Part hair to the side. 3. Tease roots at the crown for a little lift, spritz with hairspray and smooth over with a comb. 4. With the exception of your bangs, which should be neatly swept to the side, pull hair back into a mid-level pony. Secure with an elastic.5. Wind your ponytail into a bun and pin into place, tucking in any loose ends. Mist with hairspray.

Lindsay Lohan's side chignon works great on day-old hair. To get the look: 1. Gather hair into a side pony, leaving half of your hair out at the front. Secure with an elastic.2. Curl ponytail with a 1-inch curling iron.3. To get a bit of texture, grab random sections of the ponytail and tease them with a comb, then gently smooth out with a brush. Mist with hairspray.4. Tie the ponytail into a knot, pinning into place with as many pins as it takes. If a few strands pop out, leave them. You want a slightly messy finish.5. Part the front of your hair in the center and gather the sides loosely back, wrapping ends that are long enough around the elastic to cover it. Pin into place.6. Set with more hairspray.

Lindsay Lohan's wispy low bun is perfect for date nights. Steal her look: 1. Blow dry hair straight with a round brush and apply shine serum.2. Backcomb (tease) hair at the crown of your head and set with hairspray. Smooth the top with a comb or paddle brush.3. Pull hair back into a ponytail at the nape of your neck, securing with an elastic and leaving out 2-inch sections (to frame your face) plus a 1-inch section of hair underneath.4. Wrap the sections of hair that were left out of the ponytail around a one-inch curling iron.5. Start making a bun by pulling the ponytail through the elastic -- but not all the way through. The end of the pony should be sticking out of the bun, close to your neck. 6. Wrap the section that was left out beneath the ponytail around the elastic to disguise it. Secure with a bobby pin.

Lindsay Lohan's long, chocolate 'do is perfect for naturally straight hair. Steal her style: 1. Start with a trim that gives you long, slightly layered bangs but is otherwise the same length all around.2. Apply gel or volumizing spray at the crown of your head, part hair in the center and blow dry with a paddle brush while pulling hair up at the crown to get volume.3. If hair isn't stick-straight at this point, run through it with a flatiron to get it that way. 4. Smooth a quarter-sized dollop of shine serum throughout and mist with hairspray to set. (If you need more length, clip in matching long, straight hair extensions like Lindsay's and blend with fingers.)

Jessica Stroup's chic updo works perfectly on straight, layered hair with long, sideswept bangs. Steal her style: 1. If your hair is already straight, great. If not, just blow dry it straight with a paddle brush (use straightening balm if necessary).2. Gather hair into a bun, either straight back or to the side, leaving your bangs and a few side pieces out. Secure with an elastic and bobby pins.3. Make a deep side part with leftover pieces and flatiron them until they are super sleek.4. Mist with shine spray if you want an extra glossy finish. Then set the entire look with hairspray.

Ashlee Simpson's sleek ponytail is just as chic as your friend's labor-intensive updo. Best of all, it's way easy. See how to do it:1. Mist your damp hair with a generous amount of shine spray. Use a fine-tooth comb to create a slightly-off center part that extends to the middle of your head only.2.Using the fine tooth comb, comb the parted hair slick to either side, then comb the rest back and collect it all at the nape of your neck (or make it a side-pony) and secure with an elastic.3. Cover the elastic with a strip of hair and hide the ends underneath the base using a pin.4. Brush out the tail with another mist of shine spray.5. If the ends of your ponytail aren't stick-straight, use a flat iron (your trusty Sedu, perhaps?) to get them looking perfectly sleek.
