Sumi, the licensed cosmetologist whose name graces Sumi Beauty Salon, welcomes patrons into a small, homestyle setting for relaxing services that range from threading and waxing to skincare and haircare treatments and henna tattoos. Reclining chairs and minimally decorated white walls erase distractions during sessions, and large lighted mirrors allow clients to keep close watch on their faces while Sumi goes to work. Staffers also stock beauty arsenals with Dermalogica and herbal products to help remedy skin maladies including acne, wrinkles, dryness, and overly cute dimples.
