Gangnam hair salon deep treatment for dry hair: Biorn Hair
Biorn Hair Apgujeong Rodeo is a hair salon in Gangnam, Seoul, near Apgujeong Rodeo Station. After getting root straightening every 3 months, I tried its Inner Treatment with step-by-step explanations, heat steam, and a private shampoo-room massage chair. Verdict: a worthwhile treatment when dry, damaged hair needs more than home care.
