106 HAIR STUDIO
2F 20/82 Soi Prommitr Sukhumvit 39 Klongtan Nua, Nua, Watthana, Bangkok 10110
If you want the original 106Hair experience, book the Sukhumvit 39 BASE address. The site is published in Japanese and consultations run through LINE, so message ahead rather than walking in cold. The hair quality improvement treatment is the menu item to ask about by name. And note the studio takes a two-day midweek pause: closed Wednesday and Thursday both.
Up on the second floor of a Soi Prommitr building off Sukhumvit 39 sits the original 106 Hair Studio. This is the BASE branch of a four-salon Japanese-language group whose phone line, 02-6627-106, doubles as the brand.
You step up off Soi Prommitr and onto the second floor into a salon whose website is published in Japanese and whose service categories list cleanly in Japanese characters: cut, color, style, texture, and scalp care. The signature menu item is a hair quality improvement treatment that 106Hair markets as the best-selling salon treatment in Japan, ported wholesale to Bangkok. Sitting alongside it on the menu is an organic color line that the studio launched in June 2025, plus a head spa program also offered through the group's aromatherapy-focused LILAC branch on Thong Lo Soi 5. Bookings and consultations run through LINE chat rather than the website itself, which is how the four-salon group manages its book across Bangkok. The 02-6627-106 number does double duty as both phone and brand name.
The practical heads-up: 106 Hair Studio BASE is closed Wednesday and Thursday both. The five operating days run 9 AM to 6:30 PM, so if you have an off-Sukhumvit work schedule the window is tighter than it looks. Free multi-storey parking sits within the building.
Pick the BASE if you want the original Sukhumvit 39 address. The group keeps a coco106 branch on the same Soi 39 and an ANNEX ReMAKE in the Silom 6 area, plus the spa-paced LILAC up on Thong Lo Soi 5. The studio is listed as LGBTQ+ friendly and a transgender safe space in its public amenities. Go in for color and treatment together rather than a cut alone if you want the menu at full strength.
