This salon used a one-on-one system in which my assigned stylist handled everything from start to finish. The stylist personally carried out the intermediate steps as well, including shampooing and applying the treatment product. They were kind throughout my appointment, which made me feel comfortable. ![Salon where an assigned stylist gave volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-05-1yz0a-900.webp) ## How did I discuss the back curls and volume concerns? Even when I dried my hair well, only the back would puff up, and it became frizzier on humid days. There were hidden curls underneath when I lifted the outer layer, so I was always conscious of the back view that was hard for me to see. ![Inner back curls before volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-06-1k45n-900.webp) During the consultation, I said that I wanted to straighten the curls but did not want my hair to lie flat against my head. I was worried it would become flat from the crown down. The stylist divided my hair into sections to suit my head shape and hair, focusing on smoothing the curly areas. ![Back curls during the volume straightening consultation](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-07-1qmr9-900.webp) ![Information related to One & Only Hair treatment prices](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-08-1s4c1-900.webp) The price list shown during my visit was based on short hair, and there was also information about a 20% first-visit discount. However, the original post did not record the specific price of this volume straightening treatment. ## How was the treatment tailored to my hair condition? Before the treatment, the stylist shampooed my hair according to its condition. The products used were also available for purchase at the salon. ![Preparation for volume straightening tailored to hair condition](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-09-xc75l-900.webp) ![Shampooing and hair care before volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-10-bxjrh-900.webp) ![Hair care before and after volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-11-dv8p6-901.webp) ![Volume straightening considering hair condition](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-12-9eeui-900.webp) ![Hair treatment process for natural smoothing](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-13-ksbpz-900.webp) After checking my hair condition, the stylist worked so that it would look naturally smoothed while avoiding my bangs, the sides, and the areas close to my scalp. They checked the condition several times during the process. ![Volume straightening tailored to each hair area](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-14-1rsle-900.webp) ![Volume straightening process to smooth back curls](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-15-1wutr-900.webp) They also brought me bread and coffee during the treatment, so I could wait comfortably while eating. ![Bread and coffee provided during volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-16-9sqqa-900.webp) Even from the midway check, I could tell that the curls were straightening and the overall shape was becoming neater. My hair did not end up lying too flat, as I had worried it might. ![Back hair becoming smoother during volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-17-gr2zj-900.webp) ## How long did it take, and how did the back of my hair change? The treatment took a little over two hours. The biggest change was at the back. The uneven, puffed-up back of my hair looked smoother, and the hair fell calmly downward. I did not get a haircut, but it looked much neater from behind. ![Calmly smoothed back hair after volume straightening](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-18-q0ygk-900.webp) ![Straightened back hair falling naturally after treatment](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-19-6f1l5-900.webp) ## How did I care for my hair afterward? For two days after the treatment, I used only conditioner instead of shampoo, then began shampooing after those two days. I also avoided tying my hair tightly or wearing a hat for a while. The back of my head has always been a concern because it is hard to blow-dry while looking in a mirror, so I was happy that the inner curls I had worried about were smoothed this time. Even if your curls are not severe overall, if frizz in a particular area concerns you as it did me, it may help to explain that area and the volume you want in detail during the consultation. ![Result of smoothing inner curls at the back](https://img.superchart.com/images/oneandonly-gwacheon-volume-straightening/oneandonly-gwacheon-volume-straightening-20-x9mwh-900.webp) ## Where it is - One & Only Hair Gwacheon Government Complex Station (원앤온리헤어 과천청사역점) (원앤온리헤어 과천청사역점) - 15 Byeolyangsangga 1-ro, Gwacheon-si, Gyeonggi-do, South Korea (경기도 과천시 별양상가1로 15 과천청사역한양수자인오피스텔 지하1층 B05~B08호) - 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/@cotton-pad-2/oneandonly-gwacheon-volume-straightening/ · https://superchart.com/llms.txt
