Zoe Saldana walked the red carpet for the premiere of her new action flick Colombiana wearing a stunning, custom-made Balmain gown — and her minimal makeup and casual-chic hairstyle were a perfect balance to the ornate frock. Zoe's hairstylist Mara Roszak opted for a low, simple ponytail, artfully embellished with a gold chain. To see how to get this cool, party-ready look for yourself, just keep reading.

First, Roszak applied Josie Maran Organic Argan Oil ($48) to Zoe's damp hair, then blow-dried it straight. Next, she sprayed the hair with Oribe Dry Texturizing Spray ($39) and added a bit of Oribe Pomade ($34) for a more natural, rough texture.

Roszak gathered Zoe's hair into a low, loose ponytail, twisting the sides back and securing with an elastic band. She wrapped a piece of hair around the elastic, along with a small piece of chain (even an old necklace will do!), and secured by crisscrossing bobby pins through it. Finally, she set the look by spraying Leonor Greyl Voluforme Setting Spray ($36).
