I went to a hair salon in Gwacheon to dye my hair! Maybe because it had recently relocated, the salon was so clean! I wanted to tidy up my hair color, so while looking into hair salons in Gwacheon, I visited One & Only Hair Gwacheon Government Complex Station (원앤온리헤어 과천청사역점).

Lately, I’ve been drawn to hair that feels calm and neat rather than super bright, so after much thought, I decided to go for black hair dye this time. I didn’t want a black that looked intensely dark and heavy, though—I wanted a color that would make my hair look glossy and suit my skin tone naturally.

Interior of the Gwacheon Government Complex Station hair salon

One & Only Hair Gwacheon Government Complex Station was conveniently close to Gwacheon Government Complex Station, which was nice. When you visit a hair salon for the first time, the location matters, but you also quietly worry about the interior atmosphere and consultation process, right? The whole place felt clean and comfortable when I walked in, so I could leave my hair in their hands without feeling pressured. Best of all, before coloring, we first talked about my current hair condition and the color I wanted.

Toast and coffee before the consultation

Before the consultation, they prepared some simple toast and coffee for me! Haha, I had booked the very first morning slot and came without breakfast, so it was absolutely perfect! I had my hair consultation while sipping coffee.

I’ve had my hair colored continuously. When your hair color is patchy, it can make your whole impression look messy, you know? So I always go black, haha.

Between No. 3 and No. 1: choosing true black

Consultation using a black hair color chart

They showed me a chart with several colors and said my hair was close to No. 3—a little lighter than true black. They recommended No. 3 if I wanted to bring it naturally to the same tone as my roots, or No. 1 if I preferred full black.

I thought really hard about what color to choose... but fall and winter are coming soon, and I love true black, haha, so I asked them to go with black! Oh, but it seems every hairstyle has a length surcharge? For long hair, it’s an extra ₩60,000. I definitely recommend checking first before you go!

This was my hair color before the appointment. It looks especially light in the photo because of the light, right? I always go black, but seeing it fade that light makes me think my natural hair color must be quite a natural brown after all, haha.

Checking hair condition with a pre-service shampoo

They started with a shampoo before the service to check my hair condition accurately. I think I heard that your hair has to be wet to assess it properly, haha.

Calm, glossy black hair color

What I chose this time was black hair dye! I was a little worried that dyeing it black would look too heavy or make my impression seem too strong, but after doing it, it felt much cleaner and calmer than I expected. In particular, it had a subtle shine depending on the lighting, so my hair even looked healthier than before.

After coloring, it didn’t just look overly black—it gave my overall look a tidier impression, which I personally loved. Haha. I think it would be a good option for anyone who has been keeping a light color and wants a change, or who wants neat-looking black hair.

They said care products are included as a service, too! You can really feel the difference with the premium treatment~

Maybe because it was premium care, but wow, my hair felt incredibly soft. The stylist also had amazing hand pressure~~ They gave me such a strong massage, and it felt so refreshing, hahaha.

At One & Only Hair Gwacheon Government Complex Station, it was comfortable because I could explain the style I wanted and check my current hair condition together with them. This time, I completely changed the mood with black hair dye, and my overall look became calm and neat, so it felt like a proper refresh. If you’re looking for a hair salon in Gwacheon or a good colorist near Gwacheon Government Complex Station, it could be worth visiting. I especially want to recommend it to anyone who wants to change from light hair to neat black hair like I did.
