These days, it seems like there's a new trendy hairstyle every week — from opal locks [1] to tie-dyed tresses [2], it's a little hard to keep up! But we've finally come across the be-all and end-all of gorgeous hair color: smokestack. A beautiful combination of gray and rainbow, the smokestack style will undoubtedly catch on quickly.

It's the brainchild of Pravana [3] artistic color director Vadre Grigsby, and while it looks complex, smokestack color would be simple for your hairstylist to replicate. It combines five shades of black-based hues — in this case, plum, violet, amethyst, gray, and lilac — all applied in angled layers to drape in a natural gradient. Watch the how-to video to get inspired for your next trip to the salon, and trust us . . . you'll look smokin' hot.
