X-presion, the group behind Instagram-famous account @xpresioncreativos, has started some of the most popular hair-dye trends. It's created pixel hair, tartan hair, and most recently rain color hair. Rain color hair looks like raindrops are falling off the head. It also gives the hair volume and texture. It's achieved by applying a stencil to the hair and then coloring in the drops. When peeled off, the hair looks more textured. X-presion teaches its hair techniques in seminars so hairdressers all over the world can learn.
