Seongdong hair salon for purple-brown gray coverage: Urban Ground
Urban Ground Hair Sangwangsimni Station Branch is a hair salon about one minute from Exit 4 of Sangwangsimni Station in Seongdong, Seoul. I received a purple-brown tone-down color and Metal DX clinic after a one-on-one consultation for gray coverage and unwanted yellow tones; the color looked more even after a week.
