Men's haircut and side down perm in Gangnam: Divers Barbershop
Divers Barbershop Gangnam-gu Office Station Branch is a barbershop in Nonhyeon-dong, Seoul, connected underground to Exit 2 of Gangnam-gu Office Station. I watched my boyfriend receive a haircut and partial side down perm; after about 1 hour and 10 minutes, the sides and back looked neater while keeping his length.
