This is an update to my original review- years later and I still keep coming back! The new location they moved to is modern, chic, and trendy all in one! -Clean & Cozy -Welcoming employees that remember you by name -Multiple talented nail techs -Hundreds of polishes displayed to choose from -Puppy friendly Best salon yet to perfect my long nails each and every time!! read more

I booked a massage on ClassPass. The establishment doesn't exist, no answer when you call. No confirmation? They charged me a $62 no show and I had to fight with class pass to get my point back. Do not book them on class pass! read more

They lady who did my toes at first gave me 2 wounds on my toes and then I ask nicely if the other lady could do it because she the first lady obviously does not know how to do pedicure. Then the second lady did my toes again and refuses to cut my side nails. Obviously they don't have how to clean nails. They have the audacity to kick me out of the salon and told me I am rude. If I am rude I wouldn't give them a chance to have the second lady try to do my pedicure. Please do not go there because they really don't know what they are doing and they are the one who's rude to their customers. Horrible service. They wasted my time. You guys are rude to me. I did not say my feet is dirty. You guys don't know how to clean. You should sell your business. read more

LOST a customer for life! Just look at their customer service. Super rude and unprofessional. First made me download their app that wasn't fully functional and next I receive a random text with this communication. Please see photos. Wouldn't tell me their name and accused me of trying to sell them something. Very unprofessional and I am super disappointed! Please see owner's response. Just proving my point! I did not forget and that is why uploaded photos. They would receive 0 stars. read more

Made appt online for 1pm but received an update that it was changed to 2:30PM. Not what o wanted bit it was my daughters only day off. First of all there was no name on bldg but did notice lights were on. We checked in for our appt and was told to pick out a color. Which are colored "gel" nails with magnets on them. I was seated at the spa pedicure chair. My daughter was next and Selena did her pedi and was done while I was still sitting. Cass started my pedicure and they couldn't find the color I picked and then ended up with the wrong one but they found it finally. Selena then came over and finished it and had to do the parts that Cass missed. I was there from 230PM to 5PM! I mean it was a good pedi. But the time it took was ridiculous. Answering Sara the owner.. 1. my feet were not in bad condition first of all. 2. Were u there? 3. Selena finished my pedi because she didn't want to do a gentlemen's feet that walked in. 4. I'm just giving an honest review and I still left a tip. 5. You won't have to worry about me again. Thank you! read more

I recently went here for my birthday. Got a massage and facial (my first facial). The massage was good, that is where my one star is. My muscles are tight so he did a good job concentrating on what I asked him to. I do wish i would've known it was a male masseuse because i personally prefer a female. The facial was not worth the money. I wish I could get a refund! I should've asked. They use products that I felt like could be found at TJ Max or Target. I had a sheet mask and multiple other ones for the deep pore. But my skin looked exactly the same. The establishment did not look like a professional spa but just a warehouse. The staff are nice but I'm not sure who's running the show but it's a mess and the business model is weird. There also was not someone at the front desk for majority of the time me and my friends were there. Honestly, spending $200+ on my birthday for that was a regret. I did not get what I paid for. read more

If you're after GelX and you got mistakenly sent to Onyx from the Apres website, you are in for a surprise. Onyx has Gel-X but their techs aren't very experienced. My friend and I went to get my nails done for my wedding and they thought we had an appointment for two so even though she wasn't planning on getting her nails done, she decided to go ahead with it and she regretted it immediately. The soak for her gel polish she was given was boiling hot and when she told the tech, she didn't do anything to cool it down. When the gel-x were applied and she put her hands in the curing light, she felt the liquid gel burning her fingers. Again, she mentioned it to the tech, and was told "oh it does get a bit hot sometimes". She asked for a white tip with a V shape and a nude color underneath. I kept checking on her and she was so upset, she went to the bathroom to "wash her hands" - she needed a break from the "torture". My nails came out okay, a bit on the thick side and not shaped exactly like I asked, but nothing I couldn't handle. Hers? We found another salon to have them removed immediately. She was crying she was so upset at how bad they were. There was no neutral color so you could see her true nails in the V, the liquid gel was still not fully set, and was globes on her fingers. It seems like the gal she worked with may have been a first timer with a customer but if so, I'd highly recommend she practice some more before trying again. ****EDIT**** After a response from the owner, you can tell they are quite defensive. I get it -- people read Yelp reviews and you still want people to visit your business -- but to call me a LIAR on a public platform when I offered a review of our experience in order to help you improve your business and let others know how it was for us? Definitely a red flag. My friend is too kind to speak up even when she receives terrible service so she would never say anything, but she begged me to call salons along our route home just to have the work she had done here removed. She was in tears. She may have had previous damage, but when you tell the tech things are too hot, they should do something to help you, not advise you to suffer through it. When you leave the salon, your gel should be set and dry, not still tacky and in globs on your skin under your nail. She still paid for her awful nails AND to have them removed at another salon. Worst $90 she's ever spent. I reimbursed her because I talked her into having her nails done when she was just along to watch my toddler. The techs were great with my toddler, giving her the color books and samples to play with and Cassie did a great job on my nails despite having to stop and let me chase after my girl several times so I gave her a nice tip, but my friend's experience was not so good. Maybe instead of telling people who leave bad reviews they are lying, you could be apologetic and take the constructive criticism with grace and humility. Ask them to contact you without bad mouthing them and they may even delete or change their review. As for me? This response from the owner made me remove one of the two stars I have this place. I was trying to be nice, but when you call me a liar, you lose all respect from me. read more

The youngest M has this week off school, so I took a couple of days off to torment her. I know her preference would be to spend the week glued to a screen watching mind numbing videos. I decided to do a mother daughter spa day (thanks for the idea, Jill!) I'd not been to Onyx Day Spa before, but it's conveniently located and had all the services we were interested in (mani/pedi/mini facial). I called when they opened at 9am, and they were able to arrange for our pampering to begin at 10:15. Young M has never had any spa treatments before, so I was hoping it would be a special day. It was. When Cass offered me coffee as we settled in, she offered M hot chocolate. Good move! Salina did our nails, and we were both very pleased with her work. And her personality. She's warm and down to earth. As a bonus, the selection of nail colors was more expansive than most places. M especially loved the mini facial by Carrie. Two hours later, we walked out of Onyx feeling relaxed and happy. They have a great team of women! read more

please stop gaslighting people. and stop saying you aren't like others that like spreading covid or monkey pox. nobody wants to spread those. not sure what story you've made up in your own little mind but being a business person, this ain't how you handle business with your customers. if you've been in the business this long- you would know how businesses work and how to deal and handle customer relation stuff. gaslighting a possible future client is just one way of showing you got no people skills at all. here is our whole convo for reference. you're the only nail salon that do not answer phone calls at all. i guess it's your way of saying you don't want more customers. it's ok, i have already gotten my nails done at a place where everyone is so nice and amazing at doing mani pedi, got the deluxe and paid $190 and gave my mani lady $20 and pedi lady $10(because she didn't massage me good) eitherway, you're losing business with what you're doing. keep it up. Additional info: The owner did not stop at gaslighting me through her reply on my review. She also sent me a private message here. Beware. This is so scary. Business owners like this seem to be a narcissist who is so good at gaslighting. Hope this person has a therapist. I'm so glad I found the place that I did. Never ever going to spend money on any place that treat people like shit. i saw she wrote on one of her defensive replies to one of the reviews that shared their bad experience that they have been in business for 19 years, and she is telling me 30 years of business. What is it really? read more

This place doesn't exist! I used 34 class pass points and I showed up and it's an empty business!

I went in for a mani, pedi, and a prenatal massage. The mani pedi was ok and then when I went in for my masssage it was really uncomfortable. I had to ask for a pillow to keep my head up and it seemed like she grabbed it from the couches in the lobby. She was going to just massage me fully clothed until I asked if I could take my shirt off. Really odd situation. She also left mid massage for 10 minutes to speak with one of her employees. All in all, I went in for the massage at 3:20 and then it ended at 4:07 with a 10 interruption in the middle. I went to pay and asked for a receipt and she said it would be texted to me. It never was and then I saw a charge with an automatic tip on my card. It was an extremely over priced for what I received. I will not be returning. read more

Do not book a massage here. My appointment was accepted; I received several confirmation texts and reminders. I showed up and apparently there's no such thing as massage here **as a result of covid**. Gas is expensive. Time is money- and this experience was a waste of it. read more

My husband decided to surprise me with a full package at this spa. It was my birthday and as soon as I walked in, I was welcomed by smiling faces. The owner even shook my hand and said Happy Birthday. To top things off, she had even bought cake, flowers, and gave me some complimentary soaps that I enjoy so much. The services were the best I've had in a while! From the mani/pedi, body treatment and massage - I can't say enough! The staff were all professional and easy going. We actually had great conversations throughout each process- everyone was so friendly and made me feel super comfortable. I really appreciated the fact that this place is appointment only so you don't get the loud rushed atmosphere like other places. Especially considering the pandemic. It was nice to actually be there, be attended to, and not feel as if you're just another number. I got to relax, recharge and left feeling so refreshed. I needed this! I highly recommend this place and will definitely be coming back with family and friends! read more

Guys. Salina is one of the most talented, humble and sweetest people you will ever work with. She designed my beautiful nails yesterday and as small of a thing it is, I feel so much better about myself. Although I've followed Salina for a few years, this was my first time scheduling an appointment with her at Onyx. As I expected, she had a welcoming smile on her face and was ready for me on time. I'm also a professional in the beauty industry and I know all too well how a lot of talented people are big headed, gossipy and only converse with you to gossip about you to their next client. Salina is not that way at all and it's so refreshing. I would recommend her based on that alone but she has the talent as well and she's passionate about what she does. I took a photo from my kindle fire but I promise it is nothing compared to what you are in person. She is just amazing. Thanks Salina for being so professional, sweet and just downright awesome at what you do. read more

*Edit* Wow! Thank you for taking time out of your "19 years" of business ownership to attempt to make a public example of me. It looks like you come on here often to do the same thing to others. How's that working for you? Thank you also for ignoring all of my concerns, and consistently avoiding direct questions such as "Why is the address on your website incorrect?" Even after you told me to disregard Yelp info because you aren't responsible for what it says there. And despite all of the inconsistency in policy and information, why haven't you made any attempt to actually focus on solutions? Or since you already got my money, you are past caring? So not only did you take a client in my place, but you also charged my card $275 without permission? ------ Scheduled an appointment through text, because no one answers the phone. Showed up to the appointment early, but the address listed on their website was wrong--- the building was empty. Tried calling but no response. Text them that I was headed to the address on their Yelp page, but they said they gave my appointment time to someone else. Initially said I could reschedule no problem, but then said I'd need to pay all over. I learned I was charged $275 with no receipt or breakdown of what the cost was for. Was never given the no-show policy when I booked, and even though I was told three different things later(the third time I was told I'd receive partial credit) you'd think they'd work with me. I still don't know if it's even a real business, as the owner's photo is a stock photo. And the website and the yelp page say totally different things. Found the little correspondence through text to be demeaning and as if I was talking to several different people. read more

Love this place so far! Only have been once so far and I saw Selina. She was fantastic and my nails came out great! Love the vibe of the shop! Thank you so very much, looking forward to my next appt! read more

After so many months of not being able to get a pedicure, I was dying for a place that was open. Stumbled upon Onyx Day Spa looking for something local. I'm so glad I found them! Booked an appointment online and enjoyed amazing service from Salina. She listened to me when I shared the areas that needed extra work. The color turned out perfect and she was so detailed with making sure the paint was clean on the edges. Super pleased with the service. Can't wait to come back and get fancy nails. They had so many little jewels and mentioned a whole team of talented people. Pinterest inspired nails will be next, with mimosas during service. Or maybe even a girls day. It's a perfect space for it. So glad I found them. read more

I just can't catch a break with this place. Last night I booked an appointment online for an acrylic fill at 3:00pm today. I arrived at 2:50pm and there was no one at the front desk. Every time I've been here the reception desk is empty so this was nothing new to me. Around 3:00 I decided to just go to the back in case whoever was there didn't hear me come in. I went to the back and saw that the lights were off and no one was there despite music playing. I called the salon number and was told the people doin acrylic fills had left for the day and the system shouldn't have let me book an appointment. I received a half-hearted "sorry" and was told the earliest I could be seen is tomorrow morning. No offer to rebook for me or anything. I don't know, I feel like the universe keeps giving me signs to avoid this place. read more

I wouldn't say I was a regular, but I've come to this spa half dozen times and always loved it. Today I was informed that the woman who I love for massages no longer works there and is no longer the owner. I made a reservation online for 3pm. When I arrived the staff was clearly confused about the schedule. Then at 3:23 I received a text saying my appointment was cancelled because they could not accommodate it. It would of been nice to have a call much earlier in the day so I didn't leave work early for a massage that wasn't going to happen. Just disappointed. read more

First impression all the staff members are really nice. I came in to get a full set and a pedicure, this place was pretty lonely perhaps because you have to book your appointment. However, i loved being the only one in salon. Cons: -The black chairs seen in a few of the pictures are not the ones they use. The chairs they have are brown with a pattern and after sitting on them for more than an hour they are not that comfortable. - They do not use the gel you see in one of the pictures just regular powder Pros: -Not crowded - They do not use fake nails, instead shape your nail with a form and powder. -In majority of the nail salons they speak in a different language which makes me feel uncomfortable at times because i know they are talking about me. But here they all speak English. -ALEX is SUPER Detailed and patient with her work. I LOVED the fact that once she was done shaping my nails to make sure i was happy with the shape. I swear everytime I go to a nail salon either one nail is a little off and I end up fixing it at home. But definitely not the case with Alex. -Parking is super convenient - Great selection of nail colors Took a screen shot Alexa nailed it.! Will definitely be back! read more

Let me first say that this is now the only place I come to for any spa service! Booking is super easy, a simple phone call and I get two text reminders of my appointment. The modern feel of the main building is really cute & then the facial/massage rooms are incredibly relaxing peaceful. I get a lot of things done here and I absolutely love the facials, I have problematic skin & coming here consistently has kept my acne/scars at bay. I also thoroughly enjoy the massages & body wraps... I naturally carry a lot of stress in my body & the hot stone massage gives me instant relief! The body wrap/scrub literally makes me glow & id definitely recommend for any special occasion. Now on to the nails... Salina & Alex are the absolute best at nails & are very serious about getting them perfect. They both take their time to make my nails beautiful & I get compliments on them all the time! read more

Excellent customer service from scheduling an appt over the phone to receiving my pedicure. They moved to a new space which is quite nice. Cass was meticulous with my polish! The one critique I have was the lack of attention to cuticles which, along with polish, is what I look for in a good pedicure. (A great massage is always welcomed!) Particularly since it's a bit more here than nail salons. And yes, this is an upper scale salon so the pricing reflects that. But I would go back because this salon is really nice and close by. The customer service is also very good so I would certainly be open to trying other services. read more

Salina is meticulous - so although the mani/pedi takes a long time - this means she takes the time to make sure my nails look good and I am happy with them. I have been to her 3 times so far. The second time - She spent a long time trying different glitters and polishes until I found the look I was going for. She is also very sweet - so the entire experience is enjoyable. I have tried a handful of other nail places in the area. My experience with other places is that the gel manicures didn't last a full 2 weeks before they started to either bubble, chip or both. Yes you can find a cheaper service - but I like the quality of her work. This is why I am a repeat customer. read more

I went to Onyx Day Spa for my birthday (compliments of my lovely partner). I always wanted to try this location because of the reviews so I had very high hopes going into the experience. Unfortunately, it did not live up to my expectations. First, when I arrived, I was greeted by a male massage therapist who informed me that my appointment was with him. Initially, I was caught off guard because I thought my appointment was with a woman. It would have been nice to know beforehand. Because this was a prepaid gift, I rolled with it. With that said, he was very professional and gave a great deep tissue massage. The two-star rating is in reference to the "spa" manicure and pedicure that I received. I have definitely had better mani/pedi experiences. The manicurist wasn't very skilled. In fact, her technique prompted me to ask how long she'd been doing nails (it was that bad). Both services felt rushed (even though I was the only person in the shop) and the end result was poor quality. My manicure and pedicure began peeling two days later. Needless to say, I won't be back. read more

I wanted to treat myself to a full set. It had been so long since I had done them. Being on a time crunch before vacation I went to a different salon...lets just say I left very unhappy. They were sloppy, they didn't touch my cuticles, after a week it looked like they were ready to pop off, very fake looking (I know they are fake but with my job, my nails are just too weak to just had done a manicure) and I specifically asked for a "natural look". Now for the good stuff! Cass had tried so hard to get me in before my vacation but it didn't work out, but it was ok, I just dealt with it for the week. But as soon as we had the chance, she scheduled me in with Alex this morning. And, let me tell you...Alex took care of me! She knew exactly what i was looking for! I was ready to have her take them off and start all over..but another technician just advised we should just do a fill, shorten the nails. Then Alex said she'd shorten them, thin the acrylic, and instead of "filling" my set she use gel base. Then created a plan to strengthen and work on my natural nails!!! Let's just say I am sooooo much happier that I went to Onyx!! I really enjoyed my entire visit!!! read more

I was part of my cousin's fiancé's bridal party and for her bachelorette party she just wanted a spa day. The bridesmaids and I chose this spa due to the best reviews!! - I got the four layer facial from Grace. She was so friendly and attentive to my skin's needs and recommended a simple skin care regime! I loved talking with her, definitely a wise woman who cares for each customer - I received a pedicure with paraffin wax from Cassie who was super friendly as well. She painted my nails so well and my feet were ROUGH and are now so soft and supple. - My manicure was done by Alex who seriously was so patient with me. I was very indecisive about what I wanted for my nails but she recommended some polishes for what I wanted and definitely listened to everything I needed. The scrub and wax was sooooo nice on my super dry hands. Alex was definitely a perfectionist with my nails. I recommend this place to everyone!!!!!! All the staff took care of us so well and I have no regrets in choosing this place for our little staycation with the girls. I wish they were closer to me so I would go here as my regular place but sadly I'm about an hour and half away :( read more

The salon itself is not helpful at all. They couldn't even help me out when Lynn was unable to. Very unorganized and like many of the bad reviews just unprofessional. Lynn is amazing! Ask for her.

She only works Thursday-Saturday right now but I promise she is worth it. Took me 3 years to find someone worth sticking with :)) She is the only reason I go here! As you can imagine I'm torn with my rating so that's what I gave 3 stars. So 5 stars for Lynn 3 for the salon read more
