Jennifer Aniston has come a long way since her days as Rachel Green on Friends! Her trademark shag inspired a hair revolution back in the '90s, but the blonde, multidimensional layers Aniston wears today are every bit as covetable (and way more this century!). If you're thinking of emulating Jen with a modern mane, ask your hairstylist for long, face-framing layers in varying shades of cool gold. But remember to apply the lighter tones gradually—especially if your natural base color is dark. It’s always easier to go back and add lighter pieces than to correct a too-brassy color, and the process will be more gentle on your hair when done over time. In case Jen's strands aren't right for you, we rounded up more of our favorite famous hairstyles as inspiration. Click through to find out who your celebrity hair icon is now.
