14. Jennifer Aniston
Jennifer Aniston is a huge fashion icon in a lot of ways, and the way that her hair is styled falls under that category just as much as the rest of her look. So, it would only make sense that she would eventually start investing in something of that nature. On top of being the spokesmodel for Aveeno, she bought stakes in the hair care company Living Proof, became their spokeswoman, and hasn’t looked back since. Then again, neither have they. This once small, high-end company has now been able to expand and sell their products in over 1,000 locations, receiving an abundance of advertisement from this Hollywood icon. So, what do they do exactly? Living Proof’s mission is to simplify the whole hair care routine, so that you can spend your time doing more with your day and the founders did just that. By eliminating the silicone, the biotech scientists at MIT made it possible for people everywhere to wash their hair once every two or three days instead of once a day and not look greasy! Sure, there are a lot of other benefits as well, but you can check out their website to read all about it.
