    Everyone go see Selena! I started going to her over half a year ago in Redwood City. She moved here to union city and I HAD to follow her. These are my real nails and she helps keep them strong and looking beautiful! I always get compliments by people from her work. She makes it feel like home when you go to her.

    I traveled from Redwood City to Diamond#1 Nail Salon in Union City. I've been getting my nails done by Selena for years now. Selena always does a great job on my nails and very thoughtful generous person to her clients. Selena does my nails by using silk. That has protected my nails from previously damaged sets. I highly recommend the Diamond nail salon. The staff is very friendly always customer first

    Lumpy nails, uncleaned cuticles
    Miriam N.

    I barely leave ~bad~ review because I try to be as understanding as possible, but I think this review is warranted. I wanted to get my acrylic nails taken off and get gel. I called ahead to check if they had any openings that day and they told me to come in at 3:30pm. They called back saying to come in at 4pm instead. The signal was staticky so she couldn't hear me mention to add another person. When we got there, they were totally ok with taking in 2 people. There are only two nail technicians at all times. One of them was already working on someone. The other started working on me, or at least with the most focus she could give me at the time. I'm all for multitasking but this was pretty annoying. She was more so absorbed with her phone and instagram messages, which she accidentally set on vanish mode so she was freaking out about that. NAIL PROBLEMS: She started taking off my acrylic nails pretty aggressively. She kept pushing for me to get dip, maybe it was faster than gel. So I ended up getting dip. She didn't clean my cuticles at all. Another customer came in, and all of a sudden she started saying ~out loud so the customer can hear~ to tell them next time if there are two customers coming. I told her I tried telling her on the phone, and realized that they were happy to take both of us and they didn't have to say yes when we came in. I just bit my tongue so maybe she wouldn't make me bleed like the other technician did to my sister. Back to my nails: She didn't ask me what shape I wanted, I had to tell her. I'm not sure what she was planning to shape my nails if I didn't say anything. My nails came out super lumpy because she was rushing the whole time. No attention to detail. Not relaxing at all. I just wanted it to be over. Last but not least, paid $105 for 2 dip manicures. Waste of money imo. It sucks because this was my sister's first time getting her nails done and it wasn't the best. Time to never come back here.

    Dip power with gel tips.

    Ever since I found a new favorite boba shop (Sunright Studio) I will find any excuse to be in Union City. I set an appointment with Amy day of and was ready for a little self-care. Got a Pedi and dip powder/gel tips mani. (which turned out super cute). Even after my vacay, my nails are holding on strong. Going on my 3rd week actually. Amy was super sweet and attentive. She was really easy to talk to which help the time pass by. The prices are pretty affordable here so I will definitely be returning.

    Love holly! she does my nail all the time and never disappoints. my set last a long time with out breaking/chipping or rhinestones falling off. she does good quality work for the cost she charges love her work thank you holly for always getting my nails right

    Fill with design

    First time here with my two girls we each got Phils with designs. Total cost was 150 without tip. Pricing is pretty reasonable, considering going cost of other places. Most don't include the designs in their pricing Holly does. She has all the modern up today trending designs, colors and charms. The location is within a little small shopping center pretty convenient close the freeway hours or later than most show actually stood over an extra hour just to get us completed because we hit traffic and got there an hour late we didn't leave her shop until 8 PM. She takes her time does quality work. She even pointed out how my filing of my nails previously had been filed to slant the the left. ‍. Will be back again and I highly suggest you checking her out. She makes appointments walkins, the whole nine. I'm not one to sit here and critique about pricing, you get what you pay for you. If you want quality the shell out the cash for this women's artistic quality work. I hear a lot of people on her reviews complain about pricing, but her pricing is fair for the quality she does.

    Amy is so nice! She did my pedicure today. Great massage too! I'll definitely be back.

    Really enjoyed my experience here! Holly and I had a great conversation & she an amazing job on my nails. 10/10 recommend.

    Amy did a wonderful job on my nails. Totally recommend this place. Great service and friendly staff.

    I am pleased every time I go here. Amy is very creative and artistic. I think my nails speak for themselves. Her prices are great and honestly I've been everywhere so I feel I can say this.

    I went here last weekend and got a full set w Amy (I believe). I was able to get an appointment asap, I called on my way in and I live down the street. It was clean and everyone was spread out. Amy was really friendly and attentive. The nails are not lumpy or thick at all. Very clean and thin shape. I got these a week ago and so far so good no lifting.

    Very good service, like myself more after going there...

    I have been going Holly for 8 years. She is very caring, professional, loving person. I am doing waxing, pedicure, manicure. She is very good and suggests me what is best for me.

    All my toenails were like this or worse.

    Service received: Gel pedicure and mani. I called for a gel pedi and mani; they were able to take me because they weren't busy at all. Results of the pedi were not superb. The paint edges near the cuticles weren't painted cleanly. Changes the look of my toe nail shape.

As a busy working…read moremom, it's hard for me to find time for self-care, and getting my hair done every 3 months is usually the only thing I make time for. Because I don't get many opportunities to relax, I truly appreciate every appointment with Kayla. She's so gentle that I almost always end up taking a quick nap while she's doing my hair! My favorite part is when she washes my hair. Her amazing head and neck massage is such a relaxing treat. One thing I really love about Kayla is that she knows how to read her clients. She lets me enjoy the quiet and doesn't fill my time with unnecessary small talk like some salons do. Those few peaceful hours are exactly what I need. That's why I've stayed with her all these years and even followed her when she opened her own salon. I've also trusted her with my mom, my husband, my two boys, and several friends. They all love her work, and I always get compliments on my hair. On top of that, her salon is always clean, welcoming, and beautifully maintained. She's also incredibly thoughtful and always offers coffee or a drink to make her clients feel comfortable. My only advice: book your appointment well in advance because she's that good--and she's almost always fully booked!

A little background about me, cutting hair has always been a hobby of mine. I used to cut my own hair, my kids hair, and my brothers' hair, so I'm really picky when it comes to fades and detail work. Cindy has been my go to for a while now, and she's amazing at what she does. I get a haircut about every 10 days, and every time I leave feeling like a brand new person. A fresh haircut really does make a difference, it's basically makeup for guys I walk out looking like I suddenly have my life together. She listens carefully to what you want and always gets it right. She's also very easy to talk to, which makes every visit enjoyable. Honestly, half the time it feels like I'm getting therapy with a fade, no judgment, just clean cuts and emotional support. Zheng is also excellent. I used to get my hair cut by her before she went on leave, and both of them are incredibly skilled. Honestly, better than a lot of the expensive barber shops out there charging "luxury beard oil" prices. If you want a clean cut, good service, and people who actually know what they're doing, go to Hair Express and ask for Cindy or Zheng. Just don't take my appointment spot

    tl;dr: Salon surprised me with a total bill TWICE what I was originally quoted! And they didn't…read moreeven do a satisfactory job! Disgusted! I booked this appointment for a pick-me-up before my father's funeral, wanting to look good for family and friends. When I called to make he appointment, I was quoted "around $350 for a balayage" (I have a transcript of the call). Given my straight, fine, and short hair (just above the shoulder), this felt pricey, but I accepted the cost, as I had previously had good experiences at this salon. However, I was ultimately billed twice the quoted amount! This was my first time with this specific stylist.* I was charged for both a balayage and a haircut, but the haircut charge was unwarranted. The stylist offered to "quickly and easily" take some weight off the bottom of my hair because it tends to curl up. I accepted, assuming this small adjustment would be complimentary or inexpensive--not $300 for a few lousy snips! After the cuts, my hair still curled up, but I dismissed it as it wasn't the reason for my visit, and I usually wear my hair up anyway. Three hours later, the appointment was finally over and I went to the front to pay. I was SHOCKED to find that the total was TWICE what I was expecting to pay. I broke down, partly from all the stress I was under planning the funeral and partly because $600+ is WAY more than I would have EVER agreed to! I was really mad and someone came out (manager?). They took a few dollars off but it was still nowhere near the original agreed upon price. I told the stylist the most important thing was a natural looking balayage. As you can see in the pictures I took the same day as the appointment, she did a terrible job and the lines are mostly straight down my part with one weird area. It looks like I self-dyed my hair recently and it just started to grow out. It is 2.5 now weeks later and I am still SO mad, I can barley look in the mirror. I hate it! She did a terrible job and got paid good money for it. The appointment finally concluded after three hours, and I proceeded to the front desk to pay. I was absolutely shocked to find that the total cost was double what I had anticipated. I became very emotional, partly due to the stress of planning a funeral and partly because over $600 is significantly more than I would ever have agreed to pay! I was furious, and a staff member (possibly a manager) came out. They offered a small discount, but the price was still nowhere near the original agreed-upon amount. I had specifically told the stylist that achieving a natural-looking balayage was the most important thing. However, as the photos clearly show, the result is terrible with straight, distinct lines. It looks like a poorly executed dye job that is already growing out. Now, two and a half weeks later, I am still so upset that I can barely look in the mirror. I hate it! The stylist did a poor job and was paid handsomely for it. *I am choosing not to name the stylist because, as a gig worker myself, I understand people have bad days. However, I also know that money should be refunded (or billed the actual agreed upon amount!) when the job wasn't done--not just unsatisfactorily, but incorrectly.
