Models at Jason Wu sported a sleek, simple style created by Odile Gilbert for Kerastase -- the first time the designer has had models wear a down hairstyle.

To create the carefree, lived-in style at Richard Chai, Unite Editorial Director Kevin Ryan used a combination of Unite Tricky Spray and Expanda Dust. He then created an intricate bun/ponytail hybrid that required forceps and (we're guessing) a lot of patience.

We're personally just looking forward to being able to wear our gym headband to work and calling it "runway-inspired."

To create the killer topknot at Monique Lhuillier, Stephen Churchill Downes for Moroccanoil pulled models' hair into a tight ponytail, misted it with hairspray and then wrapped it around to form a loose, piece-y bun.

Sid Hayes for L'Oréal Professional drew inspiration from the early '90s for the undone, deconstructed bun at Wes Gordon. He used the new Techni.Art Volume Envy Extra Mousse (out in May) to add fullness.

Bumble and Bumble stylist Allen Wood added a touch of drama to a basic low ponytail by adding a custom-designed leather cord that mimicked the belts the models wore at Tanya Taylor. Wood used Bumble and Bumble Does It All Styling Spray on the finished style to smooth flyaways.
