"That’s my graduation photo," Aniston tells InStyle.com as she looked through her very own transformation gallery. "This is so funny, look at my bangs! That was terrible," Aniston laughs. "My mom took that picture!" Fast-forward to her days on the hit television series Friends, every hairstyle Aniston pulled off from 1994-2004 (like "The Rachel") quickly became the cut stylists knew by heart, and as if Aniston's own gorgeous hair inspired her, she is now the spokeswoman and investor with the biotech haircare line, Living Proof. After many years of different hair dos—she recently debuted a sleek new bob—Aniston admits there is just one hairstyle that she loves the most. "I always really just love my long hair, when it’s long with beachy waves. That’s always a fun, easy look, and I love the more natural effect," Aniston says. "What I have now with the cut is fun because it’s something different, but I usually like going back to the basic long hair." To see Aniston's changing looks, take a look at our gallery of her days as a graduate from New York City's LaGuardia High School to today as Hollywood's sweetheart.
