    I've been going to JK for over 3 years already, she's always been giving me good haircuts every time and knows what kind of hairstyle is good for my face. If you're struggling to find a new hairstylist I really recommend JK!

    My hair after!

    Jung Kim was absolutely AMAZING! I've been to many hairstylists in the past, but many of them do things their own way instead of listening to what I want. Jung was so receptive to my ideas and executed everything with precision! I completely trust her with my hair, and she was also incredibly sweet and personable! She has an incredible eye for styles and knows exactly what suits people. This was my first digital perm, and I was astonished by the results! From the start she was very communicative and detailed. I asked for short bangs, texture, and a soft perm wave. She delivered perfectly!! I'm so happy with how it turned out and will definitely be coming back to her. For the level of attentiveness and skill she provides, her pricing is so reasonable! She deserves to charge more! She truly needs more recognition, so please give her a chance if you haven't already! I've uploaded a photo of my hair before and after!

    Very professional & is understanding. Cute, clean & welcoming little salon. Booked Got myself a Korean perm & a haircut for my daughter. That was back in April 2025 & it's now Jan 2026! I love the more curled look, but as time goes on the perm relaxes & you get more of a beach wave, makes getting ready so easy! Will need another perm in a few more months since my har was just past my shoulders and now it's almost to my waist.

    I absolutely do not trust anyone except for Jung with my hair. She knows my hair style so well and what would be the best treatment/color/or cut depending on how my hair currently is that day. Her cuts are always fantastic. She's always so detail-oriented. She really takes her time. Her colors are always great. She tries to see what can be done without bleach first. I recommend her to all my friends. She's the best. Thank you Jung!

    I used to get a perm curl, but it was so curly that I wouldn't say I liked it. That's when I saw soft curls on IG and started searching for a Korean salon because they know how it's done. I found JK Salon here on Yelp. I read some of the reviews and decided to message her. She was friendly and very informative, so I made my appointment with her. She took me in on time, and the whole treatment did not take that long. Her salon wasn't hard to find, and the parking wasn't bad. All in all, my experience was pleasant. I will come back here again. She delivered the soft curl I asked for, and I loved it.

    Thank you Jung. My son looks amazing. He loves his new hair do and I love his new hair do. Thank you so much. You are amazing!!!!

    Jung is a professional. She is a master in her own craft. When we first went in I had no idea what to do for my son. I just asked her to give him a new hair do that is easy maintenance and that is the current style that works for him that will make him look good. Give home to boom boom wow factor. And she did just that. I have scheduled for my own haircut with her for next week. I will share it then.

    Jung Kim is very friendly, we talked a lot about our love of H mart, hehe. But most importantly she nailed exactly what I wanted when I asked for a Korean wavy perm. Got compliments of how my hairstyle made me look younger. I highly recommend her, she is very experienced and knows what she is doing.

    Jung Kim did an amazing job on my hair!! I finally got someone who did my hair color right! Love her so much, she's so sweet :)

    Can't recommend Jung Kim enough!! I asked for a soft wavy perm this time around since I got a super curly perm last time. I sent inspiration photos and she delivered!! I was tired of my flat straight hair and wanted more texture. My hair is soft and fluffy, even with the perm :). I'm so happy with the results. Jung Kim is so sweet and so fun to have a conversation with!! I look forward to my next visit with her!

    I stumbled upon this place through some searching on Yelp and saw the great reviews so I thought to give it a try! I called Ms. Kim a few hours before she closed hoping for an open spot. She was cutting someone's hair at the moment but was very accommodating and said she will give me a call back after she was done. Shortly after, she said one of her clients were able to come in a bit earlier and that she could squeeze me in on the same day! I was so thankful because most salons require appointments and are usually booked out for weeks! My initial hair was very long and pretty flat. I asked for a wolf cut with some see through/curtain bangs. I showed her some pictures and she got to cutting my hair. She gave me some advice on how to style it afterwards and even complimented my bleaching job even though I did it at home with some uneven spots lol. Ms. Kim was very detail-oriented and made sure I was ok with the length and the cut at multiple intervals throughout the appointment. She styled my hair at the end and taught me how to do it at home as well! She was extremely friendly and the environment was very cozy with pictures of other clients with their new haircuts on the wall. I had a ton of hair but she made sure to sweep up everything along the way to keep the area clean! Overall I loveeeee the haircut! She gave me exactly what I asked for and did not cut my bangs too short , which I experience a lot while going to other salons. I could tell she was an expert on how she was cutting and styling my hair. Her 23+ years of experience was well displayed! Thank you so much Ms. Kim and I will be coming back and raving to my friends about this place!

    Here she is, legit LA Ktown stylist here in Vegas! Jung Kim is awesome. She is very welcoming, clean, and of course great at what she does. She can free hand a fade and a perfectionist. She won't let you get up if she sees the slightest hair out of place that needs to be fixed. I just moved to Vegas for a job, and after finding JK, I now I look professional enough to sit in my seat. JK's shop is in phoenix salons. When you enter, take a right past the fountain and head down the hall. Studio 21 is suite 136 on your right. You deserve to look good.

    This was a long awaited transformation! I got denied by another salon for this request but it had to be fate because when I found Jung Kim I knew she could help me make this a reality. I wanted a soft curl perm with a short haircut and she absolutely nailed it. it looked almost exactly like the reference photo which I know can be difficult. she also said it would take about 2 hours and it indeed did! she was very on top of it and got me done in the time she stated. most importantly, she is one of the sweetest ladies i've ever met. and for the first time as an adult having a hairdresser that wasn't myself, I think i've hit the jackpot :) good vibes all around. thank you Jung Kim!

    I've had decades worth of haircuts that never worked for me. My hair always broke off, was prone to…read moresplit ends, and never grew. Regardless of what products I've used or any amount of hair trims, it constantly felt brittle and would tangle from how dry it was, leaving my hair looking like straw. Then I found Allison. Absolute game changer. After my first haircut with her, my hair had zero split ends and has been the healthiest it's ever been. For the first time, my hair can actually maintain length. As a California native, I now schedule my Vegas trips around my haircuts with Allison because I refuse to go anywhere else. Incredible skills and personalized knowledge. Thank you, Allison, for making me feel my prettiest ^ - ^)/

    I had a mixed experience here. Booking was super easy and I appreciated all the reminders--it made…read morethe process really smooth. The salon itself is beautiful and welcoming. My stylist did a great job with my haircut, and I could tell she's efficient and experienced. That said, I did run into an issue with the color service. The dye left visible staining along my hairline, temples/sideburn area, and behind my ears, which I wasn't informed about until after everything was done and I saw it in the mirror. The stylist did try to remove it, but it didn't come off easily, so I left with noticeable staining on my skin. I understand that things can happen, especially with different products, but I do wish there had been more communication in the moment and a more thorough final check/cleanup before I left the salon, especially since the staining was visible in multiple areas. Unfortunately, I'm not very comfortable waiting for it to fade on its own, and I'm also not inclined to return for a future service. Overall, I think this place has a lot going for it, but I hope they can improve the finishing process and post-service support so clients don't leave with unexpected issues. UPDATE: (response to Business Owner response) Thank you for the response, Emily. I appreciate you taking the feedback into consideration. I understand that staining can sometimes happen, but my concern was more around the visibility in multiple areas and that it wasn't fully addressed before I left. I've had my hair colored many times in the past and haven't experienced this level of staining, which is why it stood out to me. I'm glad to hear you'll be focusing on improving the final check and communication moving forward.

    I contemplated on whether I wanted to write this bad review and I'd like to preface by saying I…read morerarely write reviews at all. I only write reviews when it's 5 stars and I hate to spread negativity but I'd like to share my experience to prevent this from happening to anyone else. I sat on the thought of even writing a review for a week so here is my experience with Yosuke. I found Ark LV from Yelp going through all the photos and reviews and have always had positive experiences with Japanese hair stylists as I have asian hair and grew up going to many stylists who used Japanese hair methods to treat and care for hair. Given the hair stylist I love and trust is back home in NYC and I had many grays starts to growing out from my original beautifully blended bayalage, I wanted to give trust to Yosuke and chance as I thought going from bayalage to a single color would be an easy job. I started the appointment by showing him the color and cut I wanted mocked up from an image I created using AI and asked if he could do it and he responded, "Well yes, that's my job." With the confidence and the reviews and photos I've gone through, I moved on with the appointment and proceeded to have fun conversations with Yosuke throughout; I even started the appointment recording a hair transition video with him as I was super excited for a new mocha brown color from my original blonde bayalage. By the end of the appointment, after the reveal and cut, the color was a bit darker than I expected which I don't blame him for but I started to see some demarcation and waited until he was done with my layers to evaluate the final product. The haircut took no more than 15 minutes and he gave me more layers than I showed in the picture and didn't thin out the face framing layers I've experienced going to many amazing hair stylists throughout my life. He asked if I liked it and asked how I will complete my hair transition video. Here's the part that really bothered me... I had to ask if he had a mirror I can use to see the back of my head. All stylists I've experienced will always show me the final product from front, side and back to ensure I'm happy with the final product and I can instantly tell why once he handed me the mirror. Please review the photos I've shared to see the demarcation he's created. I didn't wash my hair for a week because I'm scared to see how the color will wash out but from one of the photos I've shown below, the color inconsistencies and demarcation only became more apparent. He apologized, offered to fix it and even only charged me for haircut only which is why I will give him 2 stars but if you don't have experience coloring grown out bayalage, don't take the job. I consulted with my trusted stylist back home and I couldn't get myself to go back for him to fix my hair because I prefer not to be his experiment and run the risk of my hair getting more damaged from bleach and having an even worse outcome.

I've been insanely busy lately, so I just couldn't find the time to come in sooner. ​Honestly, leaving a haircut unmanaged for 4 months usually means my hair turns into a complete disaster. I have super frizzy hair, so I normally have to flat-iron it every single day or get a magic perm just to keep a decent C-curl. ​But for the first time in my life, my jaw-length bob grew out beautifully. Even after 4 whole months, the shape held up perfectly and it was so incredibly easy to style every morning without any extra chemical treatments. The technical skill here is seriously unmatched. ​Some people might think the price is a bit on the higher side, but when you factor in the amazing longevity, the effortless daily maintenance, and how much you actually love your hair, it is worth every single penny. It's the definition of great value and total peace of mind. ​My husband also got his hair cut again today, and just like last time, we are both absolutely thrilled with how we look. This salon is a total gem!
