    Another local favorite in Diamond Bar is Kay's Nail Bar. I have been there a few times and love how Kay does my nails! She is super friendly, and every time I have been here, she's been super sweet! I love how it has turned out, and I will be coming here often! She offers regular nail polish and gel for both hands and feet. Usually I will do regular nail polish on my toes and gel manicure on my hands. Also she does do designs so if you are into that show her a photo and she will do it for you. So if you're looking for a nice place to do your nails for sure come here!

    Went to Kay's to get my gel x nails fixed and redone with a new design and my whole experience here was amazing! Kay was super nice, friendly, and easy to talk to! She was very patient and very accurate with my nail design. She also made sure I was happy with my nails throughout the entire process, and I just love my new nails so much! I will be going to Kay's again to get my nails done. My experience here has been super positive so thank you Kay~ ^^

    I'm in LOVE with my nails.

    I have found my new nail spot. Catered my nails and she was so patient with me even though I was completely undecided on my nail color. She made the experience so easy. And the quality is just top notch. She took her time and didn't rush the process, which I appreciated. She gave me a hand massage and gave my hands a little facial at the end. I love that it was just her working today and there wasn't a lot of noise. It was very much a Zen environment. Her pricing is very fair too. I am definitely going to come back when I need a new fill for a new set. Thanks, Kay!

    Kay's Nail Art is both me and my daughter's go-to place for beautiful, high quality nails. Kay's attention to details and careful work always leave us impressed. She is always dedicated to perfection. My nails always pass my careful inspection with flying colors. Beyond her skills, Kay takes the time to understand what we want, making each visit a personalized experience. She also maintains high standards of hygiene, ensuring a safe and comfortable environment for us.

    This was my first time getting gel X nails, and it was a really enjoyable experience! It was a spur-of-the-moment idea because I previously had a difficult week, and it totally made me feel better. My nail tech was super gentle and made sure to check with me every step because of the language barrier. The designed nails (with the clouds) were 5 bucks each. The nails with the stars were 3 bucks each. Gel X cost 70 bucks. The total was 86 bucks.

    The star on one thumb was $2, the moon with gems was $5, all other gold accessories were $1.

    Came in to get a gel manicure with some designs on each nail. I booked an appointment over Yelp by messaging the business and got an appointment at 1 a couple days in advance for me and my boyfriend who was getting a pedicure (his first one, he just wanted to try it out). Pedicure: We actually came around 15 minutes early and got to start my manicure about 10 minutes early which was cool. We had a great time and my boyfriend enjoyed the standard pedicure. It was $22 for around 20 minutes for the standard pedicure. He said his feet felt very smooth and he enjoyed it. Manicure: My manicure took about an hour. The person who did my nails was fast but not rough which was great. When she did my cuticles, I didn't bleed at all which is rare for me, so that was a big plus! I had a picture of what I wanted and she was able to recommend the right colors. I was also able to choose what gold nail accessories I wanted from a pretty decently sized collection. The gel manicure was $38. The marbling was $5 for each nail. Small gold accessories were $1, medium sized $2, large sized $5. My total ended up being $69 not including tip, which is somewhat expensive. I know some places are cheaper, but also I'm very satisfied with the way my nails came out. The nail artist applied several coats of gel to make sure none of the gold would come off, but my nails still weren't that thick at the end which was cool. Only problem I had was that one of the gold foiling on one finger is sticking out a little so the nail is not completely smooth, but it's a very small issue. Would I come back again? Maybe! It's pricey but you get what you pay for!

    Chipping on my R hand. Please excuse my eczema.

    This is an updated review. The owner, Kay, personally reached out to me and was willing to fix my chipped nails free of charge. I told her what my concerns were and she explained to me everything she would do. My concerns were: 1) they filed my nail down very thin so they were very fragile and had already broken 2) the gel nail polish was already chipping after 3 days of normal wear 3) my white nail polish was starting to lift on the edges Kay was very meticulous and inspected every single nail and explained to me that she would redo the chipped black and peeling white nails, but that the green was still fine (which I agreed). While waiting for the acetone to do its thing to remove the gel, she explained that she would apply builder gel to each nail, which would help to strengthen my nails. When doing my nails, she really took her time. She reshaped the nail I had broken and made sure my nails were even on both hands. She was gentle and patient, and once she was done, she went back and double checked every single nail to make sure everything was fine and that if I was still having problems, I could contact her and come back to fix it. Kay is a business owner who runs her shop with honesty and integrity. Covid hit a lot of small businesses, but Kay still remained gracious and took the initiative to reach out to me and fix her employee's work. I appreciate that she took the time to drive back to her shop to fix my nails, and I will most definitely be coming back for Kay's work in the future.

    Chipped gel manicure after 6 days...
    MOnique S.

    Went to Kay's the Friday before Christmas for a gel manicure with some Winter wonderland designs. My nails turned out grey but just 5 days later they started to chip and now the day before festivities my nails look terrible. Disappointed cause I splurged and paid $55 for this gel manicure with the design and it didn't even last a week. I wouldn't go back with the price and how long they actually lasted. Really hoped this would be my new spot.

    Come here if you want beautiful nail colors! They have so many options and the quality of the polish is great. Love my nails!

    Love the result of my nails. Everyone who works there are nice and friendly. The girl that did my nails was really patient and professional. Will definitely go back next time!

    Atalie L.

    I wanted to wait a couple weeks before posting my review on my nails so I could give my opinion on my nails to the full extent. Needless to say, I absolutely love my nails! My time with Kay was amazing-- she was very attentive and thoughtful, as well as quick with the service. She helped me take off my acrylic + gel nails and did a Japanese gel extension (gel x) with a design that I showed her. The nails have lasted with absolutely no issue thus far-- and typically at other nail salons, I have a huge problem with how quick they go, because they usually end up with uneven acrylic nails. Kay's nails are perfectly shaped and are very even-- no issues at all! It has been 2 weeks and they are still shiny and beautiful, and I still get compliments from strangers. I will definitely be coming back to see Kay!!!

    Can I make a appointment for take off gel nail?

    How much for a gel mani pedi?

    Can I know the price?

    Price varies depending on what you have done. If you choose Japanese gel I believe the starting price is around $32.

    Mia is the girl that did my toes she ate hard!!!! I been so so many nail salons and deadasss no one…read moredid my toes like Mia. Genuinely the best toes I have ever done. Pls go to her and the place is so nice aswell. They were playing good musics too. 10/10 it's such. Underrated place

    We came in on a whim to celebrate my husband's birthday yesterday and decided to treat ourselves to…read morethe most expensive pedicure on the menu--the $55 Organic Package. Unfortunately, our experience was disappointing. I understand that a men's pedicure typically takes less time since there's no nail shaping or polish, but the difference in timing was excessive. We arrived around 5:55 PM, and my husband's pedicure was finished by about 6:20 PM. I did use the restroom before my service, but that took 1.5 minutes? Meanwhile, his entire service--including the sea salt scrub, cuticle care, and callus removal--was completed before my cuticles had even been touched. My pedicure wasn't finished until just before 7:00 PM. It felt like the services weren't paced well, especially considering we came in together to celebrate a special occasion. I don't mind if one service takes a little longer than the other since I clearly had polish but a 40 minute difference for the same package felt unreasonable for the price we paid. I hope this feedback helps improve the experience for future customers who come in together. Before I get into the negative, I have to give my pedicurist 5/5 stars. She was amazing--she took her time, paid attention to every detail, and really took great care of my feet. I absolutely loved the service she provided. Even though I wasn't happy with my husband's service, I still tipped his technician $10 because I know how hard those in the nail industry work. Our total came to $125, and after tips we paid $150. I'm a licensed manicurist myself, so I understand how services should be performed and timed. I know men's pedicures generally take less time, but my husband's technician rushed through his service. She could have spent more time making sure the pedicure matched the quality and value of the package we paid for. Overall, I expected a much better experience for the price, especially since we chose the highest-tier pedicure to celebrate my husband's birthday. The quality of my service was excellent, but the inconsistency between our experiences was disappointing. I hope this feedback encourages the salon to provide the same level of care to every client. Do better.

    I normally try not to write negative reviews however, this one I did need to bring up considering…read morethat I apparently am not the only one that this has happened to. I went in for a gel manicure and pedicure appointment on April 12, 2026. My first experience with them was wonderful so I decided to book again. This time instead of calling in I used the online appointment system. I clicked the techs I wanted and it was confirmed on the screen I would be serviced by them. I also added an appt for my husband a few days before my appt online and got online confirmation that we would be serviced at the same time. Day of the appt I got a text saying my tech would be late. I said that's fine and I would send my husband in to keep his earlier appt. They then told me that the online system was incorrect. We got to the salon and while my husband was getting his service, I was told my tech was booked and I would be with someone else. I told them I got online confirmation of the tech id be with, they said it was wrong. This is where it all went downhill. I don't even remember the girl's name but I was ensured she would do a good job. I don't get mani/pedi often so I was looking forward to this. She used an efile on my nails and, like a few other comments, filed my nails so thin that a couple broke in their parking lot. She didn't really speak to me because she could tell I was frustrated at the miscommunication and was also told by the front desk to call next time if I want a particular tech. This option shouldn't be available online if it doesn't work. My nails started to burn that when she finished cleaning my cuticles I cancelled the rest of the appointment. I was contacted by the salon to try to make things better, which I appreciate, however it shouldn't have come to this in the first place. Needless to say, here we are 5/20 and I have not gone back. My nails are still so brittle that you can visible see where the nail was filed down vs the new growth. The nail on my left pinky is lifting so I have to be extra careful with it. I really thought I found my new shop because it's much closer. My old nail spot has been servicing me for 20+ years so looks like I'll be making the trip back there.
