Chrissy Teigen's hair is always looking fresh thanks to best friend Jen Atkin. Not only is Atkin the founder of Ouai and hairstyling blog Mane Addicts, but her client list is also longer than a CVS receipt. Her signature look is creating effortless beach-wave texture California girls seem to strive for.
Other notable clients: Bella Hadid, Kendall Jenner, Hailey Baldwin
