Drew Barrymore has perfected this season's must-have hair: beachy waves.

The 36-year-old actress and CoverGirl spokesmodel rocked her red strands in a lush and wavy hairstyle to attend Chanel's benefit dinner for the Natural Resources Defense Council's Ocean Initiative. Barrymore glams up this simple summer look by smoothing out her roots and adding a few defined face-framing curls.

Do you want to ride the waves like Barrymore? Celebrity stylist Danielle Caputo recommends spritzing hair with a salt-water spray to achieve that piece-y texture.
