What is sombré? First, let's take it back to the OG trend: ombré. It's every lazy girl's dream: let your roots grow out and, essentially, you've got the look. (One of the trend's redeeming qualities.) Over the past few years, we've seen this look go from dip-dyed ends to drastic color pairings — deep black roots with platinum-blond ends or red with brunette — and now it's time to refresh yet again!
Sombré, known also as "soft" or "subtle ombré," incorporates lighter shades in a more natural way. Instead of dramatic colors paired together, your base color casually transitions into lighter shades by strategically placed highlights around the face, which cascade into heavy highlights at the ends. It's a look we're seeing on some of our favorites hair color muses like Kate Mara, Mila Kunis , and Lily Collins, so we went straight to the source — their hair colorist, Denis de Souza  — to learn who's a candidate for the look, how to maintain it at home, and how often you need touch-ups.
