This is Singaporean brow-grooming salon chain Browhaus's location on Nanjing Xi Lu, inside the Sephora. If you need brow grooming, this is probably the place to go, their menu includes such procedures as threading, tweezing, tinting and "brow resurrection," which we're led to believe is a kind of semi-permanent tattoo. They also have brow- and lash-care products and services.
