Pose the question, “Who is Jennifer Aniston?” and then survey the room. My guess is, you’ll get one of two answers. Either, “That actress on ‘Friends,’” or “The woman with the most amazing hair in America.” So amazing, it’s helped her lock down a new gig: co-owner and spokeswoman of Cambridge-based hair care company Living Proof.

Living Proof was co-founded by MIT Professor Robert Langer and Polaris Venture Partners’ Jon Flint. And what stands the company apart are two discoveries: OFPMA and PBAE. The first is a molecule that can fend off moisture, which is the primary cause of frizzy hair, while the latter was developed in Langer’s lab to give hair more body.

Aniston jumped on the opportunity after learning more about Living Proof’s scientific approach. “Over the years, my hair has been subjected to everything…blow dryers, flatirons, curling irons, color, extensions, you name it,” Aniston said in a release. “After using these products, I felt like I finally discovered a solution that works every day.”

The actress called the products “proof in a bottle,” and was first exposed to the company when shooting a film in North Carolina, according to the Wall Street Journal. After the No Frizz cream left her hair with “great curls” in “100 percent humidity,” she was sold.

Aniston will help on the hair care brand development and creative marketing side of Living Proof. She’ll also be working with the company’s stylists and scientists on new products.

“Jennifer embodies everything we stand for—a unique combination of beauty and brains,” said Jill Beraud, Living Proof’s CEO, in the release. She also embodies the most envied thing of them all: a head of really, really, really great hair.

Now this announcement explains why Aniston was in Boston this past weekend. Keep your eyes peeled, though, because she’s bound to return.
