Jennifer Aniston is an investor and spokesperson for haircare company Living Proof.

The actress has signed a deal with the Massachusetts-based brand to front their range. Jennifer could also be set to launch her own line of haircare products created under the company's label.

She is set to take a starring role in marketing for the brand, including an ad campaign expected to start shooting in November. The star will reportedly have input into new products, package design and other business areas in exchange for her investment.

"I have been approached many, many times," Jennifer explained to the Wall Street Journal. "You want to be part of something that's exciting and authentic. You can't get more interesting than these scientists."

Living Proof executive Ms. Beraud explained why Jennifer was the company’s top choice of star. "We believe that beauty and brains are the best formula," she said. "Jennifer represents everything we represent as a brand."

The actress has enjoyed previous success with her creations for the beauty industry. Jennifer appeared in a L'Oréal hair spray campaign in the ‘90s and she became famous for flaunting a funky layered style in TV show Friends. © Cover Media
