I evened out faded light hair with No. 1 black dye and premium care for a calm, glossy finish. Verdict: a satisfying refresh for anyone wanting a neat black-haired look. ## Good to know - **Location**: Near Gwacheon Government Complex Station, basement level 1 - **Parking**: Parking support available - **Long-hair length surcharge**: ₩60,000 *as written by the visitor on Sep 11, 2026* ![Featured image of black hair coloring at a Gwacheon hair salon](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-01-11lh9-1200.webp) 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. > Parking support available ![Directions to the hair salon on basement level 1](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-02-caq4s-900.webp) One & Only Hair is on basement level 1, so don’t get confused—take the elevator down to B1! ## A clean, comfortable atmosphere at the Gwacheon Government Complex Station branch > A clean salon ![Clean hair salon interior atmosphere](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-03-1ow1u-900.webp) ![Clean hair salon interior space](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-04-hr481-900.webp) ![Comfortable hair salon space](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-05-tazrg-900.webp) ![Interior of the Gwacheon Government Complex Station hair salon](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-06-1hhtc-900.webp) 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. ## A one-on-one consultation with morning toast and coffee > A private one-on-one consultation ![Toast and coffee before the consultation](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-07-8lgy3-900.webp) 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 > Hair color ![Consultation using a black hair color chart](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-08-1nb0b-900.webp) 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! ## My light, faded hair before coloring > Before ![Light hair before black coloring](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-09-1y75m-900.webp) 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 > Shampoo before the service ![Shampoo process before hair coloring](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-10-tbrjy-900.webp) 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. ![Checking hair while wet](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-11-zgykq-900.webp) ![Black hair coloring process](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-12-jocid-900.webp) ## 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. ![Neat hair after black coloring](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-13-zx816-900.webp) They said care products are included as a service, too! You can really feel the difference with the premium treatment~ ![Premium hair care process](https://img.superchart.com/images/gwacheon-black-hair-dye/gwacheon-black-hair-dye-14-1dhi1-885.webp) ## Premium care and a refreshing massage 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. ## Where it is - One & Only Hair Gwacheon Government Complex Station (원앤온리헤어 과천청사역점) (원앤온리헤어 과천청사역점) - B05–B08, Basement 1, Gwacheon Government Complex Station Hanyang Sujain Officetel, 15 Byeoryangsangga 1-ro, Gwacheon-si, Gyeonggi-do, South Korea - 경기도 과천시 별양상가1로 15 과천청사역한양수자인오피스텔 지하1층 B05~B08호 - 37.4277692, 126.9920641 - Google Maps: https://www.google.com/maps/search/%EC%9B%90%EC%95%A4%EC%98%A8%EB%A6%AC%ED%97%A4%EC%96%B4%20%EA%B3%BC%EC%B2%9C%EC%B2%AD%EC%82%AC%EC%97%AD%EC%A0%90/@37.4277692,126.9920641,17z --- Superchart · https://superchart.com/en/@incheon-powder-cup/gwacheon-black-hair-dye/ · https://superchart.com/llms.txt
