At the award show in 2006, The O.C. alum perfected the middle part, long layers and loose waves.
When stars weren't going for the loose beach waves, they went for super defined curls, as showcased by Jessica Alba in 2006.
Before Miley Cyrus chopped her hair (and dyed her armpits), she was just a teen embracing the strands in front while the rest of her hair was pulled back.
Who didn't want Lauren Conrad's beachy waves with the look parted right in the middle?
Amanda Bynes' bodycon dress and waist-grazing waves were everybody's 2000s goals.
To crimp or not to crimp? Obviously, the answer was to crimped the hair and finish it off with a floral accessory. Duh.
A thick choppy fringe was the way to go in 2003.
The middle part (a total '90s trend) got an upgrade in the 2000s with a straight and slightly wavy combo.
When you wanted a beachy wave and crimped hair combo, this is what you did.
Cornrows in the front, curls in the back.
Random streaks in your hair for the win (and when you didn't want to go all the way with that dye job).
Maria Menounos had the Snookie pouf before we even knew what a 'Snookit' was.
The choppy bob, as seen on Mandy Moore in 2002.
The stick straight, yet slightly flipped out 'do + random caramel streaks = Sandra Bullock's hair at the 2000 award show.
