    Acrylic fill by Kelly - always on point!
    Nicole F.

    I am SO happy that Kelly was able to take over this shop in Castro Valley! She has always been the best nail tech I've had, and she is also amazing at waxing eyebrows. Not to mention, she is the sweetest business owner you could ever meet. If you don't like something, she will help you until you are happy with the result. She goes out of her way to make you feel welcome every time. The rest of the team is very kind and professional, and the atmosphere just feels comfortable from the moment you walk in. The quality of work is great, and the services are reasonably priced. It's become my go-to nail place. Thank you for all that you do Kelly

    Amazing nails!! I loved my nails so so much thank you! Definitely will be coming back for a new set. ladies were wonderful and friendly!

    I have been coming here for years. These ladies are fantastic. I got a 4th of July nail design. The lady hand painted it. Its absolutely gorgeous!!

    Kelly!!!!!! You ready for an amazing job. Go to Kelly. Kelly has done my nails for over a decade. I couldn't be more excited. I lucked up and got an appt last minute once I found her. Service is amazing. Hospitality is making a come back. Being pampered is part of the experience. It's our self care. Take good care of yourself and go see Kelly!

    I really love this nail salon. All of the ladies are super friendly and they always get me in and out quickly. I would say it's probably my favorite nail salon in the East Bay area. Julia has done my nails the last few times and she always does a thorough and great job. They have a huge variety of colors to choose from. It's also always a relaxing and decompressing environment. The prices are also very fair. I've been to other salons in the area where they definitely up charge for every little thing. The only downside of this place is sometimes it's hard to find parking. But I always go very early in the morning so I never have an issue. I will definitely be coming back here!!! Julia is my go to girl and she's super friendly and great!

    Cat eye nails!

    Just had my nails done with Kelly at Diamond nails. She did a fantastic job with cat eye nails. I'm so pleased I found her.

    I've come to Diamond Nails since I moved to California in 2010. These ladies are the absolute best. Relaxing massage with pedicure and Lisa serves flawless nails every time. Beautiful atmosphere and chill place to be 7 days a week.

    Thank you Kelly!

    Hi, I've been looking for Kelly (who used to work at Mimi's), does she now own Diamond Nails?

    I'm not sure if Kelly worked at Mimi's, but she used to own The Nail Salon and now owns Diamond Nails.

I moved to Hayward recently and had been bouncing around trying to find a new nail spot--came across Sam's page because I was curious about Russian manicures and she does them beautifully. Just a heads up on the booking process: the site directs you to request an appointment, but it's not auto-confirmed--Sam has to accept it manually. For my first appointment, I booked for the next day and wasn't sure if it was going through, so now I just DM her directly to check in. Super easy once you know the flow. Sam herself is super sweet and easy to talk to. She recently went solo with her business, so it's just her now--and honestly, I love that. It's chill, one-on-one, and you can tell she really cares about quality. She has a gorgeous selection of colors and uses high-end products, which I think is why everything lasts so long. The first time I went, my nails were in sad shape and I honestly didn't think they'd bounce back. A month later? I've got legit nails I'm proud to show off. If you're looking for a new nail tech who's talented, kind, and really knows her stuff, definitely give Sam a try. I've already planned my next visit.

    For the first time had a good experience. Got gel X let's see how long they last. Good serviceread more

    I really wanted to love this place because the salon itself was beautiful and the staff was…read morefriendly, but unfortunately the prices and quality were incredibly disappointing. First, I was shocked that a basic kids' pedicure for my 8-year-old son cost $27. All they did was trim and clean his nails, followed by a short leg massage. That price seems extremely high for such a simple service, and there was never any discussion of pricing beforehand. The biggest issue, though, was my own nails. I paid about $55 for my gel manicure--$35 for gel polish, plus an additional $20 for a French tip and a small Mickey design. When I woke up the very next morning, less than 24 hours later, the entire gel polish had already peeled completely off one of my thumbnails. The French tip and Mickey design on other nails were also already lifting and peeling. I've never had a gel manicure fail this quickly. If I lived closer and didn't have to drive across the bridge, I would absolutely return to request a full refund because this level of quality is unacceptable. Between my dad, my two kids, and me, we spent close to $500, so we expected much better workmanship. My daughter's nails actually turned out great, so this review is strictly about the quality of my nails. One other thing that bothered me was my dad's pedicure. The staff kept offering him additional services during the appointment, and he kept saying yes without realizing each one came with an extra charge. By the end, his pedicure totaled over $100 plus tip. I really think pricing for add-on services should be clearly explained before they're performed so customers can make informed decisions. I've attached photos showing my thumbnail the morning after my appointment, along with photos I took the night before. It's incredibly disappointing to spend this much money and have a gel manicure start peeling in less than 24 hours.
