Works best on: Wavy hair, chin-length or longer
Hairstyle how-to: Step 1: To get Jennifer Garner's hair texture, apply mousse to hair and either blow-dry with a diffuser (scrunching as you dry) or loosely French braid hair and let air-dry.
Step 2: Once hair is dry use a large (one-inch) curling iron on low heat to bump up your waves (wrap large sections of hair around the iron, don't clamp it in).
Step 3: Spritz hair with a light-hold hairspray and tousle with your fingers to loosen curls.
Step 4: Create a deep side part and tease the crown of hair for a little lift.
Step 5: Take one to two inch sections from each side of your head, near your temples, and pull them back below your crown. Make sure to leave face-framing pieces hanging.
Step 6: Tie the two sections into a knot (like you would a shoelace) and pin into place, leaving the ends hanging.
Step 7: Curl face-framing pieces by holding the iron vertically and rolling it away from your face.

Works best on: Chin-length or longer, straight or wavy hair
Hairstyle how-to: Step 1: Apply a spray gel (if your hair is fine) or mousse (if your hair is thick) and diffuse hair, holding your head upside down to add volume to your roots.
Step 2: Once hair is dry, scrunch a dime-size amount of gel or mousse on hair to add a piece-y texture.
Step 3: Take the bottom half of your hair (from the ears down) and secure into a low, loose bun.
Step 4: Next, divide the top portion of your hair into small sections and tease the underside of each section, then twist and loosely pin each one into place above and around the bun, keeping the volume on top.
Step 5: Spritz with hairspray to finish.
