1-hour 3-step Ayounche hair clinic at Sangwangsimni salon Oreudeubi
In short
Oreudeubi Sangwangsimni Station Branch is a hair salon on the first floor of the Centras commercial building in Seongdong, Seoul, a 9-minute walk from Exit 1 of Sangwangsimni Station. On a day off, the writer had a roughly 1-hour Ayounche hair clinic in three steps — moisture, nutrition and collagen — followed by a steamer, a massage-chair shampoo and a scalp massage from designer Haru. Dry, frizzy ends came out calm and smooth, a result worth the hour.

How to find Oreudeubi Sangwangsimni Station Branch: 9 minutes from Exit 1
My hair's been feeling frizzy and dry lately, so on my day off I booked an Ayounche hair clinic with Designer Haru at Oreudeubi Sangwangsimni Station Branch. The salon is a 9-minute walk from Exit 1 of Sangwangsimni Station.



I booked ahead through Naver Reservation, and they're running a 30% first-visit discount (20% off cuts, excludes partial treatments) — first-timers, definitely take advantage of that~


Even on a weekday afternoon, Sangwangsimni salon Oreudeubi Sangwangsimni Station Branch was packed with customers.

The interior had a calm gray-toned feel, and there was a separate waiting area, so I could relax comfortably while waiting.

Before: dry, frizzy ends led to the Ayounche hair clinic
Before. They said you can only judge the true condition of your hair after washing it once, so they shampooed first and took the before photo. The lower part and ends of my hair felt dry, and even applying essence at home couldn't stop the frizz, so I felt I needed proper salon care with the Ayounche hair clinic — that's why I chose it.
*Ayounche hair clinic / about 1 hour

Ayounche hair clinic step 1: moisture care
Step 1, moisture care. A moisture-rich product is used to make the hair soft and hydrated, so it doesn't tangle and can better absorb the nutrition step that follows.

Designer Haru applied the Ayounche product generously, working it in with skilled hands — you could really feel the moisture soaking in!

Midway through, they let me use a phone charger, so I could comfortably charge my phone while getting the treatment.

For a set amount of time, a steamer was used so the moisture product applied to my hair could be fully absorbed.


I'd had a fasting InBody scan at the health center that day so I hadn't eaten anything — I really wanted an iced Americano but held back and chose rooibos tea instead 💗 They also served light snacks haha.
Steps 2 and 3: nutrition and elasticity, then collagen
Step 2, nutrition and elasticity supply. Since step 1 had the hair soaked with moisture, this step pushes nutrients deep in, and again a steamer is used after applying the nutrition product to help absorption.


Step 3, forming a protective layer and injecting collagen. Once moisture and nutrition care is done, the final step adds collagen!

Massage-chair shampoo and scalp massage to finish
Once all three steps were done, I got to lie back in a massage chair for a gentle rinse — total relaxation. Isn't this really the best part of a clinic treatment? My body had been aching and I wasn't feeling great that day, but the massage chair at Oreudeubi Hair Sangwangsimni Station Branch gave me some serious healing.
Designer Haru gave a light scalp massage while I relaxed in the massage chair — amazing! After a gentle rinse, the Ayounche hair clinic was complete.



After: smooth, frizz-free hair, and how to keep it that way
After. My hair had such a glossy shine. Thanks to the generous amount of Ayounche hair care products applied, it definitely felt stronger, and the frizz was completely gone, replaced with calm, smooth hair~ They said it's fine to wash my hair the next day, and if I want the effects to last as long as possible after a clinic treatment, they recommended washing with lukewarm water for about a week.
That's my review of getting a proper healing session and the Ayounche hair clinic with Designer Haru on my day off at Sangwangsimni salon Oreudeubi Hair Sangwangsimni Station Branch — very satisfied.
