Musab Balbale, merchandising vice president for Walmart U.S. Beauty, has been given the task of reinventing the retail giant’s beauty business. “It’s such a rapidly changing category between indie brands and heritage brands,’ Mr. Balbale said. “Definitely, the pandemic has changed things. Beauty certainly was one of the first categories we saw come back. After the initial shutdown, people were focused on their appearance, whether it was teeth whiteners or lipstick. Beauty can be a small indulgence.”
