Federal Way · Since 1993 · Appointment Only
Japanese thermo‑magic straightening.
A rare specialty from Mr. Ha, perfected over thirty-plus years. Silky, natural, and built to last. Clients travel across the South Sound for a single appointment.
One chair at a time. Four-to-six-hour appointments. Imported Korean care. The difference is entirely in the hands of the person holding the iron.
Why Moa — 01
A craft most salons don't offer, done by people who have done it for decades.
Federal Way is full of salons. Moa is not trying to compete with any of them. We do one thing exceptionally well, and the rest of our menu exists to support the people who come for it.
Japanese Thermo-Magic
Our signature. A precise heat-and-cream straightening process that leaves hair silky, natural-looking, and frizz-free for six months or more.
Since 1993
Mona Yoo opened Moa in Federal Way in 1993. Mr. Ha has been at the chair perfecting Japanese straightening for just as long. Muscle memory you can feel.
By Appointment, One at a Time
Quiet studio, careful pace, no overbooking. You get the stylist's full attention from consultation to the final blow-dry.
02 · Why Customers Drive South
The straightening
that lasts.
Japanese thermo-magic straightening — also called Yuko or thermal reconditioning — permanently restructures the hair's bonds using a precise combination of cream, controlled heat, and a careful flat-iron technique developed in Japan in the 1990s.
Done right, it leaves hair pin-straight and glass-smooth while still moving naturally. Done wrong, it damages hair for years. Very few stylists in the South Sound have the training and patience to do it at this level. Mr. Ha is one of them.
A full appointment runs four to six hours depending on length and texture. Results last six months or longer, and new growth is the only thing that ever needs a touch-up. We use the SKR hair-care system imported from Korea.

05 · The Chairs
Mona Yoo and Mr. Ha.
Two stylists. No assistants. No double-booking. The studio is small on purpose — that's how the work stays this careful for thirty-three years running.
Mr. Ha
Senior Stylist & Straightening Specialist
Three decades behind the chair. The reason clients drive from Seattle, Tacoma, and Olympia for a single Japanese straightening appointment.
Mona Yoo
Owner
Mona opened Moa in 1993 and has run it the same quiet way ever since. Honest consultations, careful color, and the belief that great hair is built one client at a time.
A four-hour appointment can't be hurried.
Japanese straightening is section-by-section work. There is no shortcut, and there is no second client in the chair next to you. That's the entire reason Moa exists this way.
