Gwacheon hair salon magic setting C-curl for a layered bob: One & Only

In short

One & Only Hair Gwacheon Government Complex Station is a one-on-one hair salon on basement level 1 of a building near Government Complex Gwacheon Station in Gwacheon, Gyeonggi. The writer had a magic setting C-curl perm and a damage-prevention clinic on a frizzy layered bob whose curls had dropped, and the treatment took about 2.5 to 3 hours. The C-curl at the ends held well right after the salon blow-dry, but the curl direction came out somewhat different when self-drying at home the next day, so the verdict is that essence or curl cream is needed to maintain it.

I visited One & Only Hair Gwacheon Government Complex Station (원앤온리헤어 과천청사역점), a hair salon in Gwacheon, for a magic setting C-curl perm and a damage-care clinic, and here is a record of the whole process.

Where is One & Only Hair Gwacheon Government Complex Station, and what is the vibe?

It is close to the subway, so it is easy to get to, and the clean interior caught my eye from the entrance. Next to the door there were business hours and a yellow umbrella stand as an accent piece.

Inside, there is a display area with hair care and styling products neatly lined up. The whole space is a modern, bright 1:1 treatment area, so I could get my service in a comfortable atmosphere.

My hair before the treatment and the consultation

Before the treatment, my hair was a layered bob with the curls mostly loosened and frizz left all over.

This time we decided on a magic setting C-curl perm: smoothing the frizzy texture on top and putting a neat C-curl in the ends. To prevent the hair damage that can come with a heat perm, we also added a damage-prevention nutrition clinic.

What are the steps of the magic setting C-curl perm and clinic?

The magic setting C-curl perm and clinic at One & Only Hair Gwacheon Government Complex Station was done 1:1 by one designer and took about 2.5 to 3 hours. The order was shampoo and softening, winding setting rods with heat treatment, magic press, then neutralizing and rolling the C-curl.

2. Winding setting rods and heat treatment

  • After rinsing out the softener, setting rods were wound mainly on the ends of the hair.
  • To keep direct heat off the hair, it was secured with sponges and clips before going under the setting machine.

3. Magic press and root ironing

  • After the setting heat treatment, a magic press smoothed out the curliness and flyaways on the top section.

4. Rolling the C-curl

How did the magic setting C-curl perm look right after versus self-drying the next day?

Finish at the salon on the day

Once everything was done at One & Only Hair Gwacheon Government Complex Station, the designer finished with a blow-dry style, and the C-curl was nicely set at the ends.

The next day, after shampooing myself

When I shampooed the next day and dried my hair at home with a hair dryer, the magic-treated top and the C-curl below looked somewhat different from how the salon blow-dry had set them. The surface texture and curl direction came out differently depending on your own drying habits.

Because it is a heat perm, you need to smooth the hair with a moisture essence or curl cream when drying after shampooing.
