Schlenger's how-to: Brush hair back and secure in a high ponytail. Add hair extensions to your ponytail if you want to amp up the bun. (We love Hair U Wear Dancing with the Stars Put On Pieces Glamarama, $20.) Lightly backcomb the ponytail to create texture in the bun and loosely wrap hair around the base, letting the bun expand and slightly flatten. If you are using extensions, wrap your hair around the added piece. Secure with pins and spritz with hairspray.

Blake Lively's Bohemian Bun
Best for: Smooth textures, but varying hair lengths will work, says Schelnger.
Schlenger's how-to: The trick with this look is to not worry about perfection. Start with a higher ponytail in the back of the head. Work with small sections of the ponytail, wrapping them up and securing them haphazardly with pins at the base. Allow loose ends to fall naturally. Pull hair out of the ponytail to frame the face and finish the perfect "messy bun " look.

Mandy Moore's Ballerina Bun
Best for: With a smooth, polished blowout, all hair types can work, says Schlenger. Braiding hair is a quick and easy way to add interest to this simple shape.
Schlenger's how-to: Use a shine serum (we like Paul Mitchell Super Skinny Serum) from root to ends, and blow-dry hair with a natural-bristle, round brush, getting lift at the root. Find your natural part and maintain it while pulling hair back into a ponytail at the center back of the head. Braid the tail and wrap it around the base, tucking the ends under the bun. Secure with pins.

Amanda Seyfried's Accessorized Bun
Best for: Mid-length hair of all textures, says Schlenger.
Schlenger's how-to: To prep the hair, blow-dry with a volumizing mousse (try Herbal Essences Body Envy Volumizing Mousse, $3.99) lifting at the root and polishing the ends with a natural bristle brush. Backcomb the top section of hair from the crown to hairline. Pull hair back in a high ponytail, keeping volume at the top and tension on the sides. Wrap one-inch sections of the ponytail around two fingers, allowing pieces to slip out for texture. Secure with bobby pins and finish with a headband two inches back from the hairline to break up the volume.

Kate Upton's Girly-Glam Bun
Best for: This style can be achieved with mid- to long-length hair that's been blown out.
Robles' how-to: Blow out hair for a smooth, voluminous finish. (Try Oribe Grandiose Hair Plumping Mousse to really pump up the volume). Next, section your hair, making a u-shape on the top of your head (from the bangs to the center of head, top only). Create a low ponytail with the remaining hair and twist it tightly. Wrap the twisted hair around the center of the ponytail until it is in the shape of a bun, and secure tightly with bobby pins. Spray it with a hairspray and then smooth it with a little bit of wax.
Tease the top section towards the direction (left or right) of your choice. Rub a little more wax into your hands and start pulling your hair back, gathering it all together. Wrap the rest of your hair around your bun and secure with pins.
From the runway to the red carpet, the bun hairstyle has been influencing women since its first appearance in ancient Greece. While it has taken on many forms (ballerina, knot, braided) and meanings (in Chinese history, a woman's bun revealed her marital status), it is a true style staple. A go-to for a polished look -- or even just to disguise a bad hair day.
Right now the bun is seeing sexy updates at every turn. Hot starlets (or really, their stylists) are reinventing the wheel, creating new, cute ways to wrap hair around a ponytail.
So go ahead -- put some bravado behind that bun. Here's how.
