Curly: Messy Topknot
On humid days when your ringlets are totally unruly but you have just minutes to tame them, take a cue from AnnaLynne McCord and go for a high bun. Let some curls pop out and pull down the pieces around your face for a deliberately disheveled effect. Use a drop of shine serum to define the loose spirals.

Curly: Bouncy Blowout
Even girls with super-curly hair like AnnaLynne McCord can master the perfect wavy blowout. The key is to work with small sections, using a large, round brush. Be sure to keep the blow-dryer aimed downward to prevent frizz. When you're finished, use a wide-barrel curling iron from your ears down to create loose waves. Smooth down fuzzy pieces with a styling cream.

Curly: Half-Up and Natural
It's great to embrace your curls and let them do their thing, but that doesn't mean you have to put up with frizz. Use a super-moisturizing shampoo and conditioner followed by a smoothing cream or serum. For AnnaLynne McCord's half-up look, gather the front two inches of your hair (from temple to temple) and secure the section with a bobby pin.

Curly: Slicked-Back Chignon
When you're so used to having lots of curls around your face, a sleek updo like AnnaLynne McCord's will make you feel ultra-chic. Start with hair that's been blown straight (you can also use a flatiron if your spirals are extra-thick), then backcomb at the crown for volume. Use a mixed-bristle brush to smooth hair back into a tight bun and mist with hair spray.

A half-up style like Gabrielle Union's is a great way to work second-day hair. Mist sections with a thermal protective spray before flat-ironing them (skip the roots, since you want some volume). Then, use a brush to smooth the front section of your hair (from ear to ear) back and secure with bobby pins or a slim barrette.
