Gold medalist and super-cutie Nastia Liukin has partnered with Herbal Essences to sell haircare products and make herself more famous. We support that.

We also support the half-updo advice in the above video. The half-up look, recently totally rocked by Duffy in the Mercy video, is sexy and smart. It's a wholesome, substitute teacher-esque look that almost everyone can pull off.

Nastia reportedly used Herbal Essences hairspray during the Olympics. That's pretty serious.
