Former FRIENDS star Jennifer Aniston was so desperate for a new look after the hit series ended, she cut all her hair off, hated it and immediately added hair extensions, which ultimately ruined her hair. The star caused a sensation with her "Rachel" haircut while appearing on the show and immediately regretted chopping off her trademark tresses. She explains, "After Friends, I wanted a different look, so I cut my hair. Obviously, I wasn't thinking clearly. "So I decided to have a couple extensions, never knowing you end up with 400 things in your head that cause your hair to break off. "Nothing destroys your hair faster than extensions. It's taken a year and a half to get my hair grown out."
