Holographic Hair Is Now Trending, and It's Mesmerizing

True story: When I briefly dyed my hair blue nearly two years ago, I thought the pastel trend would surely fade within a matter of months. The same notion occurred to me again last year, when I opted for a shade of rose gold. And yet, months later, rainbow-hued strands are still everywhere—and every sub-trend seems to be more innovative than the last.

Take this holographic variation, for example, which has been dominating Instagram over recent weeks. First spotted at Ross Michaels Salon in Seattle, the hue features a silvery base with sheer, opalescent colors layered on top. The result: an otherworldly aesthetic that would do Lisa Frank proud.
