While getting models in the '70s spirit with loose flat-iron waves, hairstylists backstage at Alice + Olivia added colored powder to the ladies' hairlines for a fuller, polished effect. According to TRESemme Global Stylist Justine Marjan, use an eyebrow powder because those colors typically are ashier than eye shadow colors, and thus, will match your hair better, like brow powders from Anastasia Beverly Hills and Kelly Baker Brows. Pro tip: Marjan advised going one shade darker than your hair for dimension and depth.
