Jennifer Aniston turns 44 on February 11, 2013 (we know, she doesn't look a day over 30!) and whether you love her from her Friends days or the countless movies she's made since, she's one of Hollywood's biggest actresses.

Not only is she one of the most sought-after stars in Hollywood, she's also a style icon. She has impeccably classic style and has been gorgeous and chic since the day she set foot on her first red carpet.

But it's not her style we're concerned with today. Shocking right?! As we were pondering what we love most about this mega star, in the end, her hair wins. We're sure you're familiar with the term "the Rachel" haircut? Yes, when Jennifer Aniston was on Friends as Rachel Green, she set off a frenzy of women dying to get their hair cut just like her character. Probably the defining hair look for the late 1990's, Aniston's locks were the envy of women everywhere.

Take a look at the gallery above to see Jennifer's hair transformation through the years - even when she's past her Friends days, she still has the most enviable hair in Hollywood.
