Gangnam hair salon ash brown tone-down dye: Biorn Hair
Biorn Hair Apgujeong Rodeo is a hair salon in Sinsa-dong, Gangnam, Seoul. A level 6 ash brown tone-down color neutralized the orange and red tones that had surfaced in my lightened long hair, with the full service taking about 1 hour. Verdict: a satisfying choice for a calm, dark ash brown look.
