Up or down, sleek or tousled, there's a runway-inspired hairstyle that will work for you. Here's how to replicate the prettiest ones—straight from the pros working backstage at the fall fashion shows.

Where we saw it: Lanvin (shown), Pucci
How to get it: This summer staple will still be going strong right into fall.To create the "easy, girly" braid at Lanvin, Guido applied Texturizer to wet hair for hold, then roughly blew the hair dry to maintain its texture. He added a center part, then braided the hair starting at the nape of the neck, leaving the front pieces free.

Where we saw it: Ralph Lauren (shown), Prada, Balmain
How to get it:The bouncy, cheerleader-esque ponytail is taking a hiatus in favor of lower, more understated styles. To create the sleek version at the Ralph Lauren show, hairstylist Guido first ran Redken Fashion Work 12 through dry, straight hair to prep it and add hold, then pulled the hair into a low ponytail at the nape of the neck. An allover spritzing of Shine a glossy finish.

Where we saw it: Oscar de la Renta (shown), Marc by Marc Jacobs
How to get it: To create the soft, touchable waves that bounced down the runway at Oscar de la Renta, hairstylist Orlando Pita started by blow-drying the hair sleek, then parting the hair at the center. He tucked the front pieces of the hair behind the ears and pinned them in place so that the pins were invisible. Using a one-inch curling iron, he then curled the hair from the nape of the neck down. He back-combed the ends to add texture and set the look with Hair Spray.

Where we saw it: Chanel (shown), Dolce & Gabbana
How to get it: The classic chignon has been around forever, but this season, it got a new twist with a sweep to the side. At Chanel, McKnight first created a low side-part with a comb when the hair was already dry, then added a light misting of hair spray. He then combed the hair into a low side ponytail just below the ear. He teased the end of the tail, braided the last two inches, fastened it with an elastic, and rolled everything up into a ball, lightly securing it with bobby pins.

Where we saw it: Nina Ricci (shown), Miu Miu, Giambattista Valli
How to get it: "It's dream hair—very French, ultrafeminine, and beautiful," said Guido of the voluminous half-up hair at the Nina Ricci show. To create it, he first applied Cushioning Blow-Dry Gel from midshaft to ends, and Bodifying Cream-Mousse at the crown, before blow-drying the hair with a tiny one-inch round brush. He then formed pin curls and left it all to cool. Once the hair was released, Guido created a center part, lightly teased the hair at the roots, and then pulled back a one-inch section of hair from above both ears and secured it loosely. "These pieces will fall out," he said. "It's very casual."

Where we saw it:Balmain (shown), Chloé, Marni
How to get it: There are always a few styles that work for the laziest girl out there, and the superlow, superloose ponytail at Balmain was the ultimate one. To get what he called "Kate Moss hair," hairstylist Sam McKnight spritzed the hair with water (the only product used), then mussed it up with his hands. He created a center part before gathering the hair into a low ponytail about an inch or two from the ends so that the models' long layers hung free.

Where we saw it: Valentino (shown), Rodarte, Prada, Chanel, Nina Ricci
How to get it: From ornate jeweled headbands to simple barrettes, hair benefitted from a little careful embellishment this season on the runways. At Valentino, Guido created a soft, low ponytail, and dressed it up by wrapping a black ribbon around the model's head as a sort of DIY headband, then tying it just below the ponytail. "It's easy, but has personality and glamour," Guido said.

Where we saw it: Prabal Gurung (shown), Jason Wu, and Haider Ackerman
How to get it: Allover, full-blown wacky color may still be reserved for the Lady Gagas of the world, but a streak or two of a shocking hue is having a moment. At Prabal Gurung, hairstylist Didier Malige added pastel-pink-dyed extensions to the models' hair for gentle hints of color. After dampening the hair with Coiff Oceanique Tousled Wave Spray, he roughly dried the hair. He then curled random pieces of hair with a large iron to create texture and finished up by adding the colored extensions and back-combing the hair at the back of the head.

Where we saw it: Gucci
How to get it: It might sound crazy to intentionally coax out frizz, but combining it with sleek, smooth hair (in one style) will balance out any unruliness. At Gucci, hairstylist Luigi Murenu created a ponytail that was polished in the front and crimped and a bit wild in back. First, he prepped the hair with mousse before parting it at the side and adding hair spray for shine and control. He then gathered the hair into a ponytail at the nape of the neck and tied it with an elastic before crimping and back-combing the tail itself for volume.

Where we saw it: Ralph Lauren (shown), Prada, Balmain
How to get it: A low side part instantly adds sophistication and drama. At the Gianfranco Ferré show, Guido used the technique to punctuate the '60s-inspired ponytails. After applying Blow Dry Lotion to the hair, he blew it dry with a boar-bristle brush, blasting the roots with extra hot air for additional height. He created a deep side part so the hair fell softly over the forehead and slightly over one brow, then gathered the hair loosely at the nape of the neck and secured it in place.
