Jennifer Aniston's ever-changing hairstyles became a cultural phenomenon back in the mid-'90s with "The Rachel," her Friends character's signature look. Since then, Aniston has come a long way with the help of friend and stylist Chris McMillan. While her look evolves, the effect remains the same: pretty, sexy, easy hair in a natural-looking shade of blonde.
1999: Aniston arrives at the Emmy Awards with a hippie-chic twisted style. Faux dreadlocks become a sought-after party look.
2000: Sleek, relaxed, and parted down the middle — Aniston makes this simple style seem modern.
2000: After years of ultra-long locks, Aniston has her hair cut to a dramatically different chin-length bob. Here, she wears it wavy.
2001: She wears her bob pin-straight with tons of movement. Women everywhere ask their stylists for a serious chop.

2003: Aniston's red carpet style at the Emmy Awards is effortless: a classic blowout with a side part.
2004: With side-swept bangs, loose waves, and a rich, dark blonde color, Aniston looks radiant.
2009: This simple, elegant, braided look from the Oscars continues to be popular today.
2009: Classic waves, an easily maintained length, and shiny, multidimensional color epitomize Aniston's laid-back glamour.
