Jennifer Aniston

She burst onto the scene as a dark-haired, bright-eyed girl next door. After winning the role of Rachel on Friends, Aniston caused a hair phenomenon in 1995 when her updated shag was copied by women everywhere. Her friend and stylist Chris McMillan says he simply "chopped off" Aniston's wavy hair to achieve the look. Now a full-blown movie star, the Marley & Me actress keeps it long, shiny and very sophisticated. Aniston does, however, like to play around with color-lip color, that is. Says makeup artist Robin Siegel, "I've used so many different colors on her-pinks, reds, browns. Jen likes to experiment!"

1990: Aniston lands a role in two TV series, Molloy and Ferris Bueller.

The wavy-haired star got her breakout role as Rachel Green on Friends.

"This was the original Rachel, with layered shoulder-length hair," says hairstylist Chris Macmillan of the Friends star's cut.

Aniston tried wild-child faux dreads for the Emmy Awards. "She did this look once and never went there again," says makeup artist Robin Siegel.

Aniston shined on at the L.A. premiere of The Break-Up.

"There's such a freshness about her look," says makeup artist Angela Levin. "She likes clean, glowing skin with soft, neutral makeup."
