DAYONE Head Office vs Gangnam Branch – Which One Should You Choose?

DAYONE has multiple branches in Seoul, with its main headquarters and the branch at Gangnam Station being the two most frequently compared locations.

• Head Office (437 Gangnam Avenue): Offers a wide range of services, complete equipment setup, and high foot traffic — it’s recommended to make reservations in advance. It’s easily accessible on foot from Gangnam Station, and as the flagship store, it boasts top-tier capabilities.
• Gangnam Branch (423 Gangnam-daero): Comprehensive range of core treatments, fully equipped with advanced devices, relatively low customer traffic, easily accessible on foot from Gangnam Station, and offers more personalized service along its premium treatment pathway.
