Sideswept bangs create a fun, flirty feel, no matter what your hairstyle. They also help by making your hair look thicker and more voluminous, which is something every girl can appreciate. If your hair is medium-length, you have lots of styling options. If you prefer your hair parted down the middle, there are a few hairstyles in particular you can rock.
With your hair parted down the middle, pull up just a small section of hair at the front, getting rid of any part showing there. Hold the hair down on your head, leave a couple inches of hair flat, and behind that make a couple of twists in the hair. Slide bobby pins in over the twisted bit to keep the hair pouf in place. This isn't a Snooki-rific pouf because you're only using a bit of hair to keep that center part behind it, but looks chic and polished, a suitable style for day or evening events.
For a chic twisted pullback style, start by pulling out a section of hair from one side -- just behind the hair in your fringe -- a couple inches wide. Twist the hair backward and hold it against the side of your head, then pin it in place. Do the same on the other side, either behind your fringe if you have a bit of bang hair on this side too, or otherwise the hair right at the front. Mist your hair with some hair spray to set your style.
A side chignon works with center-parted hair, and with medium-length hair you have enough to make a voluminous bun, which is what you want for this style. Pull your hair together to one side and start twisting the hair -- which way you twist doesn't matter -- and as the hair starts wrapping around itself, form a bun shape and hold it against the side of your head. Pull out a bit at the hair to get a messy look, then slide bobby pins in around the outside of the bun to keep it in place.
Maybe you just want to keep things simple and get a basic blowout. It's a good way to show off your medium-length hair, and is a style that works from day to evening. Apply a straightening cream through your hair, blow dry with a round brush, lifting the hair up when drying around the roots area, to get lasting lift. Flat iron over your strands once your hair is dry, and finish with a touch of smoothing serum to add shine and fight frizz.
