The Coziest Winter Hair Colors, According to Celebrity Stylists

Craving a little extra oomph in the depths of winter? Giannetos suggests adding a soft radiance with caramel highlights. "It's a great, subtle way to add dimension to dark hair," says Giannetos. Amal Clooney's naturally dark shade is studded with caramel-tinted highlights that enhance her hair's body and movement. "You can ask your hairstylist to add in touches of caramel and a honey blond to really lift brown hair," adds Giannetos.
