It's time to settle down! I only got a cut, but it caused a real stir. I work on the 3rd floor, and even people on the 1st floor who I'm not that close with kept telling me how pretty my hair looked! So I decided — no more salon-hopping, One & Only Hair Gwacheon Government Complex Station is now my regular place! ![The newly built building housing One & Only Hair Gwacheon Government Complex Station](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-04-126d6-900.webp) ## Three minutes from Gwacheon Government Complex Station: is parking easy? One & Only Hair Gwacheon Government Complex Station, well known for its layered cuts in Gwacheon, is in a newly built building. There is an underground parking lot, but when I visited on a weekday afternoon, spaces weren't exactly plentiful. That said, it's within a 3-minute walk of Gwacheon Government Complex Station on Line 4, so it's very convenient if you're taking public transit. ![Salon entrance and basement-level space](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-05-ejs7r-900.webp) ![Spacious salon interior with treatment seats](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-06-edhnp-900.webp) ## Inside One & Only Hair Gwacheon and the Ojua treatment menu One & Only Hair Gwacheon Government Complex Station, well known for its layered cuts in Gwacheon, has a very spacious interior.

The one you have to do every month! I really don't want to, ugh. Doing it once a month keeps damaging my hair. But if I skip it, the gray hair is so visible in an obvious spot that even my husband, who sees me every day, tells me to please get my roots done. ![Root color treatment in progress](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-09-1s0kn-900.webp) ![Drink and snacks provided during the treatment](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-10-krlub-900.webp) While my roots were being colored, they gave me a nice drink and some snacks. ![Explanation image of the Ojua protein clinic lines](https://img.superchart.com/images/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/gwacheon-oneandonly-hair-diorum-clinic-layered-cut-11-1o4xl-966.webp) ## Ojua protein treatment: Immurise line vs Diorum line The Ojua protein clinic at One & Only Hair Gwacheon Government Complex Station, well known for its layered cuts in Gwacheon, is fully customized per client. There are various lines available so you can get the clinic that matches your hair's condition. I was recommended two: from Milbon, the Japanese premium hair care brand, the Ojua clinic lines Immurise and Diorum. The Immurise line is a 'hair strength care' line for hair that's severely damaged and weakened by repeated bleaching, coloring, and perming. It's said to focus on strengthening the protein bonds inside the hair, restoring it to a healthy state that doesn't crumble under damage. The Diorum line is Ojua's top premium aging-care line, used when hormonal changes with age, aging itself, or frequent treatments cause hair to lose moisture, elasticity, and shine all at once. Its biggest feature is that it goes beyond ordinary nourishment to bring life back into the hair. It's said to act on the protein that makes up hair and holds in moisture, densely filling in hair that's become dry and hollow-feeling with age. It leaves hair feeling moist down to the ends, with healthy elasticity that gives lift to limp hair. True to a premium line, you can immediately feel the softness and the luxurious change in hair texture right after use. ## The result: Diorum treatment, root color and layered cut together After getting the protein clinic with the Diorum line, root color, and a layered cut, I heard so many times from people around me that my hair turned out great. If you're looking for a salon in Gwacheon that's good at layered cuts, I highly recommend One & Only Hair Gwacheon Government Complex Station!! ## Where it is - One & Only Hair Gwacheon Government Complex Station (원앤온리헤어 과천청사역점) - B1F, B05–B08, 15 Byeoryangsangga1-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/@slow-drip-gyeonggi/gwacheon-oneandonly-hair-diorum-clinic-layered-cut/ · https://superchart.com/llms.txt
