We’re only a couple of weeks into the new year, but it still feels safe to say that Y2K nostalgia is not going anywhere in 2023, and the latest hair color trend to sweep the beauty world is proof. We’re calling it now: “Hair frosting” is poised to blow up in the next few months. We spoke to Tylor Johnson, expert hair colorist and founder of Nous Haircare, to find out everything you need to know about this fresh take on early-aughts frosted tips.        What Is Hair Frosting?Hair frosting is a hair color technique that involves adding cool-toned highlights, usually to brunette hair, but you can try this look on any hair color. “Hair frosting typically focuses on the bottom of the hair and the face-framing highlights, keeping everything subtle and cohesive to evenly blend no matter how your hair moves,” says Johnson. “It’s one of my favorite ways to maintain dimension without being overly highlighted!” Concentrating the color towards the bottom of the hair is what makes this trend a playful riff on the oh-so memorable frosted tips look that reigned supreme in the early 2000s.
