The magazine quotes Chung's stylist George Northwood who explains how he recreates the Jane Birkin look with a modern twist. According to Northwood, "this is a simple, one-length bob, but it’s cut into for a shaggier feel."
What's more, this look suits all hair types and face shapes. To get the color, Northwood tells Elle UK to "ask for a baliage technique, it focuses color through the ends of the hair rather than at the roots, giving a natural sun-kissed look."
Northwood styles Chung's hair with Kérastase Oléo-Crème, for lived-in texture. He uses a diffuser to dry the hair. You can also "rough dry" hair by drying half way and then letting hair air dry and you scrunch it with your fingers.
