Absolutely terrible customer service. I arrived right after opening when the salon was practically empty, yet they refused to take me without any reasonable explanation. It's hard to understand how a business can turn away a paying customer when there are open stations and no visible wait. First impressions matter, and mine was that they simply didn't care about earning new business. If this is how they treat potential customers at the start of the day, I can't imagine how they handle people when they're actually busy. I took my business elsewhere, and I won't be returning. There are plenty of salons that value their customers and appreciate the opportunity to earn their business. read more

LUCKY ME. I ended up in a hotel in Beverly Hills/West Hollywood and needed (desperately) a mani-pedi. Found Kosmo on Yelp and got an appointment, plus ended up with brow service too. My ONLY regret is that I live on the East Coast and can't keep up with my nails here. Fantastic service, chill atmosphere. read more

Kosmo Nails Boutique - Gel French manicure and pedicure. - Nail Salons Near Me - Los Angeles, California

Came here a few years ago and never went back. Expensive and nails chipped after a week.

I love Fahimeh for threading my eyebrows! She's a true artist! Patient, kind and amazing!

Nami is amazing!! She was super kind and collaborative to get my inspiration come to life. I'm so obsessed with my nails I can't stop looking at them and showing them off. Kosmo nails always does a great job and the quality you get is the best i've gotten (LA native and have been to MANY salons). Their hard gel is strong, durable, but applied so precisely it looks like I have nothing on!! Highly recommend this salon and Nami for an attentive and precise tech :) read more

You can tell she genuinely cares about her clients and her craft. She takes the time to listen to what you want and checks in along the way to make sure you're happy with the shape and look. My brows always come out even, natural, and CLEAN!! Always keeping the shape of my brows in tact. Highly, highly recommend her to anyone looking for a great threading experience!

I've been coming to Kosmo Nails for almost 3 years now. I see Mona and she always gets me right, my nails turn out perfect every single time. She's detail-oriented, takes great care of me, and makes the whole experience relaxing and fun. The salon itself is great too--tons of colors to choose from, the staff is friendly, and it never feels rushed. Parking is also easy, which is a huge plus--you can grab a meter out front or park in the lot behind the building. Can't recommend enough! read more

I've been seeing Mona for over 3 years now, and she has completely transformed my nails! She helped me grow out my natural nails when I thought it was impossible, and every design I've asked for has always come out exactly how I imagined and sometimes even better! Not only is she super talented, but she's also funny, easy to talk to, and incredibly patient. She never rushes, pays attention to the little details, and makes sure I'm happy before I leave. The salon always feels welcoming, and with Mona, it's like visiting a friend who also happens to be amazing at nails. If you're looking for someone who can do beautiful nail art and also care about the health of your natural nails, Mona is the best! I always look forward to my appointments with her. read more

I came here to visit Fahimeh for eyebrow threading. She is the best of the best! I am very picky with who I go to for eyebrows and I can wholeheartedly say I trust Fahimeh to do a great job each and every time. I've been a longstanding customer of hers for years and will not go to anyone else. She is incredibly talented and consistent. Her kindness and calming energy is an added bonus. I am so glad I found a local spot for my eyebrows! Thank you, Fahimeh!!! read more

By far my favorite nail salon in the area. The all female staff is so nice, detail oriented and professional. The atmosphere is relaxed. They play top hit music, usually have reality tv playing without volume with subtitles and the staff are quiet (not chatting or yelling across the salon, iykyk). Their color selection/ brands offered is amazing too. They do get busy on weekends, so be sure to call to make an appointment. They are great at honoring appointments and sometimes turn away walk-ins in order to do so. I have nothing but great things to say, so please check them out. read more

I love this nail salon! Mona is my go to and is soooo amazing at what she does. She's really talented and can do any design you show her. I always leave so happy with my nails after Mona does her magic. Highly recommend! read more

Kosmo Nails Boutique - Nail Salons Near Me - Los Angeles, California

I really wanted to like this place, went in for a regular manicure, and everything was fine, I could overlook the painful cuticle pushing and the dirty looking tools that are "sanitized", but halfway through, I ended up not liking the color the manicurist was putting on and she said I could find a different one if I didn't like it and I felt bad for changing my mind, but she was nice enough to let me change the color. She was definitely talking about me in another language, which I didn't appreciate. Then after I went to pay she charged me $20 extra for a color change service without letting me know first and then said that she told me which she definitely did not and gave me a lot of attitude. $54 for an average manicure before tip is a lot (I still tipped) and if I knew I probably would've stuck with the original color. Color change is a separate service, shame on them for taking advantage of customers and charging me for 2 services instead of one, because she felt like it, even if she wasn't finished with the manicure when we changed colors. Won't be returning here and would advise others not to go here unless you want surprise charges without communication. EDIT: Should have read the other reviews first before going here. I'm realizing now that manipulating and intentionally overcharging people is a common thing that they do. read more

Emma at Kosmo is exceptional. Her gel manicures are flawless and long-lasting, her designs are next-level, and her ability to repair broken nails is unmatched -- she somehow makes them better than before. She's precise, never rushed. I've never been happier with my nails and can't imagine going to anyone else. Emma is the one. read more

The prices for a regular gel mani + pedi is very reasonable! I believe gel mani is $40 and pedi is $50. But something to note: they charge $5 for removal even if it was done at their salon. I've been going to Mia and love how detail oriented + gentle she is. She takes her time to clean and paint your nails. Also very sweet! The parking is easy (rare on the west side). They have their own private lot in the back. read more

The girls here do amazing work! This is my second visit with Angie and she kills it everytime. She's so attentive to detail and she makes sure that you're comfortable! Angie did my Gel X nails and they lasted me for over a month. They all stayed on and never budged/chipped! I definitely found my favorite nail salon and nail tech! read more

I will highly recommend Mona!!! She has transformed my nails from weak and thin to long and healthy. Mona is gentle, caring, and engages in great conversations.

DO NOT GO HERE!! My nails were perfectly fine before going here & now I have Onycholysis & my nails are literally separating from my nail bed. I want to puke. I got my nails done 2 weeks & 5 days & I got hard gel, during my service the UV nail lamp was super hot & I kept having pull my hands out & I immediately didn't like my nails they were way too thick & not shaped well at all which is why I got them done again so soon only to discover this. I don't know if it's because of the heat or the chemicals in the product or bacteria from their shop but this has never happened to me before & I can 100% say it's because of how my nails were done here. I want a refund. This is horrible read more

Kosmo Nails Boutique - I'm gonna be sick - Nail Salons Near Me - Los Angeles, California

They purposefully overcharged me. I got a gel manicure and asked for a cat eye design. Mind you it wasn't a full new set- it was a fill because I had my nails done 2.5 weeks prior. Cost me 110 dollars. They did a great job but the cost absolutely surprised me and I'm pretty certain they tacked on extra charges because the salon was extremely slow. *edited: I went to a Mia or Mona- she was polite and did a good job trying to make sure I liked my nails and accommodated my request! I did not experience any poor customer service just maybe some added surcharges read more

I don't like to leave poor reviews but I can not let this be ok. I booked an appt for Mona, from a referral, and was 30 min early. When it was time, I now know,Mona couldn't honor my appt because she was working with a customer. Another tech told me to sit at 2, I asked for Mona, she turned around to Mona, they spoke in their native language, then she said ok pick a color. Once i sat down, she began to do my pedicure. The pedicure was mediocre and this was a gift from a friend, who frequents this location and recommends to everyone at her office. I asked for Mona specifically because of the great job she does. I asked my tech what her name was she hesitated and said Mona. Which was untrue and she didn't seem to care about her service. She went very fast and afterwards my feet were not soft and she acted like she didn't wanna give me another coat from the streaking look of the polish. I had to get the front desk lady, who was nice, to help me put my shoes on and give me the hardening spray since I had regular polish. The lady next to me had fans on both feet and the spray offered to her. So I don't think I got my complete service. Once my tech finished, she immediately went to the break room. I was told by another lady that the lady I had was actually named EMMA. So she blatantly lied to me. That is unacceptable considering the area, Beverly Hills, that they service most. I also feel discriminated against, which normally isn't the case for me being a very polite and cordial person. The atmosphere is nice and very luxurious in esthetic but the service from EMMA and Mona allowing the lie to live, when she was sitting right next to me working on another lady, is unsatisfactory at best. I would have respected the fact she was busy and honestly I could have waited because I was referred for her service and that's what I desired. I have never experienced this and I'm not sure if this is the place to go. read more

Kosmo Nails Boutique - french acrylic manicure - Nail Salons Near Me - Los Angeles, California

Very unprofessional and not worth it. The customer service here is terrible. I booked a manicure and pedicure together specifically to sit in a spa chair due to back pain and to have both done at the same time. Instead, they made me sit in an uncomfortable chair for the manicure and said no one was available for the pedicure. The tech, Bella, was rude and dismissive, ignoring my concerns about back pain and refusing to accommodate me with back pain and my appointment as scheduled. After finishing my manicure, she told me to its time to pedicure--which defeated the whole purpose of booking both together. The manicure itself was poorly done, yet they still charged me $100. Very unprofessional and not worth it. read more
