## In short

One & Only Hair Gwacheon Government Complex Station is a hair salon on the basement level of the Hanyang Sujain officetel, 191m from Exit 1 of Gwacheon Government Complex Station in Gwacheon, Gyeonggi, where one designer handles each client from start to finish. After a consultation about hair left dry by perms and color, the salon ran an Aujua Aquavere clinic treatment and finished with a layered cut, about 2 hours in total. A week on, the hair still felt soft and sat neatly, which made the visit well worth it.

As the cold wind starts blowing, my hair keeps getting drier and frizzier... ㅠ I was so stressed out every morning drying my tangled, frizzy hair that I went off to get a clinic treatment.

The place I visited was One & Only Hair Gwacheon Government Complex Station, a hair salon in Gwacheon! It was recommended by people around me, and this time I finally went to check it out myself :)

## Where is One & Only Hair Gwacheon Government Complex Station, and what is the salon like?

One & Only Hair is located on the basement level of the Hanyang Sujain officetel. It's 191m from Exit 1 of Gwacheon Government Complex Station.

It's close to both Line 4's Gwacheon Government Complex Station and a bus stop, so it's convenient by public transit, and if you drive, you can park in the building!

Since it's a newly built building, it felt clean, and even though it's on the basement level, it's floor-to-ceiling glass, so it had a bright, open feel,

![Spacious, comfortable treatment area at One & Only Hair Gwacheon Government Complex Station](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-05-1bwae-900.webp)

and inside it was really spacious and comfortable — plus I loved that you barely smell the usual perm or dye chemical smell that most salons have.

## One designer per client: how this Gwacheon hair salon works

One & Only Hair operates on a 1:1 designer-responsible system.

Usually when you visit a salon, the designer only handles the main treatment while assistants help with the in-between steps and shampooing, but here one designer personally handled everything from start to finish, so I could trust the process even more.

I was treated by Head Designer Minjeong, and she carefully handled every step from the clinic to the cut!

![Getting a clinic consultation with Head Designer Minjeong](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-08-1pynn-900.webp)

With the Aujua clinic, you can choose customized care from various lines depending on your hair concerns and current condition — since my hair was overall dry and lacking moisture from perm and color damage, we went with the Aquavere line after consultation.

## What happens during the Aujua (Aujua Hair Care) Aquavere clinic

![Aujua Aquavere line hair care products](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-09-1b0dl-900.webp)

First, it started with a thorough shampoo of my scalp and hair.

![Shampooing the scalp and hair before the clinic](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-10-1hco8-900.webp)

After letting it sit for a bit, she used a wide-tooth comb to untangle the knots section by section, and somehow my hair already felt a little more filled-in even before the actual clinic started?!!

After that, she applied the Aujua products in order, but instead of rinsing after each step, it was a layering method where the products build up on the hair for care.

Head Designer Minjeong divided my hair into sections, applied the products generously, and handled them carefully, so I could already feel the softness kicking in before the clinic was even done, haha.

During the treatment they also brought out drinks and a light snack, so I could relax through the whole process,

![Drinks and a light snack provided during the treatment](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-13-1py63-900.webp)

![Massage chair area where the final care was done](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-14-1sh9n-900.webp)

and the last part of the care was done in a massage chair! After sitting for so long, finishing up in the massage chair felt great — even my body loosened up.

### The layered cut after the Aujua treatment

After the clinic, I also got a layered cut. I'd had my hair cut elsewhere before and still had a bit of perm left in it, but she trimmed the overall line while keeping as much length as possible, which I was really happy with. For reference, the clinic plus layered cut took about 2 hours total!

## How the Aujua clinic held up a week later

![After hair once the clinic and layered cut were finished](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-15-vd4ji-900.webp)

The after shot once the clinic and layered cut were both done!

![Side view of the calm, settled layered cut result](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-16-1ctd3-1200.webp)

It's a shame I didn't get a before photo, because my hair had been completely puffed up and frizzy — but after the clinic and cut, it was calm and settled all over, and the softness when I touched it was on a totally different level..!!

![Close-up of the softly settled hair ends](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-17-48cvz-900.webp)

What satisfied me most was the hold! I usually get salon clinics fairly often, and in a lot of cases the hair is only soft right after the treatment and goes back to normal within a few days,

but this time, about a week later, my hair is still soft and settled, so I'm genuinely happy with it!!

![Discount event notice for One & Only Hair Gwacheon Government Complex Station](https://img.superchart.com/images/gwacheon-onlyone-hair-aujua-aquavia-clinic/gwacheon-onlyone-hair-aujua-aquavia-clinic-18-1xifd-754.webp)

Right now, One & Only Hair Gwacheon Government Complex Station is running a discount event for first-time visitors, plus a discount for building residents and shop staff.

If you're looking for a hair salon in Gwacheon, or if you're struggling with dry, frizzy hair like me, give One & Only Hair a try! I'm going to keep up with home care and get regular clinics on schedule, haha.
