Worn formally or casually, the half-up hairstyle trend can be altered to fit your own taste.
Ashley Greene's beautiful half updo is timeless and simple. This look is great for those with face-framing layers.
Get the Look: Use a comb to part your hair down the middle. Spritz your hair with tousling spray (try Macadamia Professional Tousled Texture Finishing Spray, $20; birchbox.com) to give it volume and texture. Take half of your hair and pull it back, keeping it low, and secure with bobby pins. Leave out some pieces in the front to frame your face.
Reese Witherspoon nails the classic pouf with subtlety. This look is perfect when you want to pull your bangs off your face for the day.
Get the Look: Separate a section of hair at the top of your head -- how much you choose to style is up to you. Brush out this section of hair to get it as smooth as possible. Secure with a small elastic band. Push your hair forward until you get the volume you want, then secure bobby pins over the elastic.
Jessica Chastain looks close to royalty in this crownlike hair technique, which can be created in a matter of seconds.

This 'do is all about sleekness. To flaunt this look like J-Lo, flat-iron your hair prior to styling your ponytail.
Get the Look: Use a brush to bring the top half of your hair into a tight ponytail. The goal here is no lumps or bumps. To hold down flyaways, use a hair gel or smoothing cream (try Chi's Infra Gel, $14; overstock.com). If you need more hold, finish with a strong-hold hairspray (Suave Extreme Hold, $3; walmart.com).
Diane Kruger shows off a changeup on the topknot. Remember this look for the next morning you hit "snooze" too many times.
Get the Look: Separate the top half of your hair from the bottom half and secure with an elastic, as if you were styling a half ponytail. Simply tease the ponytail with a comb (this will make your bun look more full) and wrap the hair around the base of the ponytail. Finish off with bobby pins, adjusting the bun however you'd like.
Kate Middleton is known for her elegance, and this hairstyle is no different. Pair it with neat curls, and anyone can own this look like the duchess.
Get the Look: Spray your roots with a dry shampoo (we like Klorane, $20; net-a-porter.com) and a touch of flexible-hold hairspray (Matrix Amplify, $30; walmart.com). Back-comb the top half of your hair to pump up the volume. Tie off that section in a ponytail around the middle of the back of your head.
