The 60's gave us mod mini dresses, checkered everything, fabulous one-piece swimsuits—and most importantly, French actress Jane Birkin. Her dirty, honey-blonde ombré locks that defined French girl hair continue to fuel our piecey hair goals, especially the sun-kissed highlights she debuted in Italian-French film La Piscine. An adaptation of the novel of the same name by Jean-Emmanuel Conil, the drama-crime film is set in summertime on the Côte d’Azur, the dreamiest backdrop for Birkin's beachy mane poolside. Ahead of our newest Sun of a Beach Ombré Spray—a sun-activated lightener that brightens light hair colors 2-4 shades and lightens darker hair colors to a coppery bronze—we're breaking down how to get Jane's glowy look from La Piscine, ahead.

  1. Spray Sun of a Beach Ombré Spray (coming soon) on clean towel-dried hair and comb through 
  2. Bask in the sun for 5-10 minutes until natural-looking highlights appear
  3. Apply OUAI Rose Hair & Body Oil to ends for hydration and all over your body for that rich b*tch glow
  4. Soak hair in a OUAI Treatment Masque after the day is over for shiny, sun-streaked highlights
