Though we were completely mesmerized by mirror nails, the trend felt incomplete to us. As true nail junkies, we believe that shiny is good, but sparkly is even better. That's why we're singing the praises of holographic powder.
It's very similar to chrome powder, which nail techs use to craft those highly reflective mirrored manicures. But instead, holographic powder utilizes iridescent pigments, which reflect rainbow hues when struck by light. A mere waggle of the finger becomes hypnotic.
However, even more entrancing than the finished results is watching the application process. Nail pros take holographic powder (like this one from Nails21) and rub it into a prepolished nail. The more the artist presses on the pigment, the more it seems to glow. It's then sealed in with a UV topcoat, which creates a glassy finish. (Regular topcoat will make the powder look gritty).
