Chahong Room Yongsan is a hair salon in Seoul that offers cuts, coloring, and perms. Many customers come for layered cuts and brown-toned coloring. After consulting on face shape, skin tone, and hair condition, the stylists work in the requested style, such as wave perm, cloud perm, or C-curl perm. Visitors who arrive early receive brunch and a drink, and during shampooing they can get a scalp massage or hair samples.
