Screens where shoppers can virtually test out Garnier hair colors are coming to Walmart. L’Oreal’s Garnier brand worked with ModiFace to create their Virtual Shade Selector, which initially launched online. Now, the augmented reality beauty tool is rolling out to 10 Walmarts, along with other select retailers like Walgreens, Wakefern, and Meijer. The high-tech experience will include a one-minute diagnostic test followed by the chance to try on recommended shades from Garnier’s product line. (MediaPost)
