I was definitely expecting Zoe Saldana to wear blue at the 2010 Oscars (Na’vi Princess, where art thou?), but I was swept away by the lavender-lilac-amethyst-purple-violet Givenchy couture number that she ended up wearing on the red carpet.

Her hair was done in a super chic updo, created by TRESemmé Celebrity Stylist Mara Roszak. Roszak wanted ”an editorial look because she was wearing Givenchy. We also didn’t want the hair and make up to compete with the dress so we created an elegant but effortless look.”

Here’s how you can recreate Saldana’s Oscars 2010 red carpet ‘do:

1. It’s all about prepping the hair with mousse! I am a huge fan of the TRESemme Naturals line, and was pleased to find that Roszak had prepped damp hair with TRESemmé Naturals Lightweight Mousse. Then she blow dryed her hair upside down.

2. Roszak separated the crown from the rest of the hair and pulled back the sides into a tight pony. Then she pulled the hair almost all the way through but left the ends tucked into a ponytail holder. Note that it wasn’t a PERFECT ponytail, with a few pieces left outside the bun for a slightly messy look.

3. Then she teased the top part of the hair and criss crossed bobby pins to hold the hair in place securely. She also sprayed Saldana’s updo with TRESemmé TRES TWO Extra Hold Hair Spray.
4. Here’s a stylist secret! Spray hairspray on finger tips and gently pull the hair around the face with your fingers to loosen the hair, giving it an organic effortless look.
