The Haircare Video

Courteney Cox appears on video, dressed in a very simple white robe, and she opens the conversation by saying; "Lola Vie... what does Jennifer Aniston really know about hair?"

She then picks up a Lola Vie hair product, and proceeds to effortlessly and casually slather it into her wet hair.

The camera observes the simplicity of her hand motions as she runs the Lola Vie haircare through her dark tresses, and then it abruptly flips to a whole new version of Courteney Cox.

This time, Courteney appears wearing a button-up shirt and a pair of jeans, with her hair completely redone. Her locks casually touch her shoulders without any frizz, any mess, or any hassle, proving that Aniston's products are really as easy to use and effective as they claim to be.

Courteney follows up with her own question by saying; "I guess, a lot!"
