Matte nail polish is back. Nail polish that is completely shine-free, like, well, like when you put Wite-Out on your nails because you’re that bored. I forget when this trend was last “in”, but OPI has a matte nail polish line out. ManGlaze has been marketing unshiny men’s nail polish for a little while. Knock Out Cosmetics has a “flatte” line of polish (the pink version is descriptively called Calamine). And Zoya has a limited edition of MatteVelvet colors. I’ll stick to the shiny and leave the matte for the walls.
