    Tips with dip that lasted over 4 weeks!
    Morgan B.

    I got these tips with dip 4 weeks ago today!! I have never had tips last this long. Not a single nail has chipped, broken, or popped off! I bite my nails and have nubs, so the tips barely even had anything to glue to. Amazing job by Cosmos!!!

    Out of all the nail salons on 18th street, and maybe all of DC, this is my new favorite nail salon! The first two times I came as a walk in to get a gel mani. I had no qualms and was very happy with how my nails looked and no chipping issues - very long lasting. The last two times I saw Kim and got liquid gel. She likes doing designs and so I just let her do her thing. It takes about an hour to prep and put on extensions and another half hour for the polish and design, so make sure you account for the time! Love coming here and I will be back.

    I do not know how this salon has averaged four stars. I just moved to the area and had tried a few salons, and this is the worst of them all. The people were very nice and I really wanted to like them but this is just unacceptable, especially for the price. Not featured in the photos is a cracked nail on the left hand (it doesn't photograph well). I've never felt more ripped off in my life. For $100 with tip, I have a literal crap manicure where I regret even getting them done and a smudged pedicure. I'm trying to go back to get them fixed, stay tuned if they charge me ... I wouldn't be surprised. They were booked the last day so I couldn't go in. Oof. And after I wrote that review, another has chipped -- my thumb. Photo posted. And now my left index is chipped (day 4)

    Obsessed with this place!!! Amazing prices amazing staff

    I have been a loyal customer of Cosmo Nail Bar for nearly two years and these past two years I have had the most polished appearance I have ever had. This place is truly a gem and you must treat yo self to the experience. Located on the main strip of Adams Morgan, Cosmo is anything but off the beaten path. The salon is one of those bigger on the inside kind of places that has a large back room to accommodate extra foot traffic (pun intended as the back room is for pedicures). There is also a large area for manicures. The place operates like a high efficiency beehive and I have never had to wait for more than 5-10 minutes for a WALK IN! Amazing, right?! Now I always stick with the classic pedicure, and I will sometimes add on a classic manicure if the moonlight strikes me. I'm fancy, but not that fancy. The classic pedicure only costs $28. That's it. A BARGAIN. During the week they have happy hour specials and it's even cheaper! Now I was first wary of such a low priced pedicure, but I have NEVER been disappointed. They do a fantastic job every time. They don't cut corners, just nails. They also go above and beyond to scrub your lower legs with a sugar scrub, lotion them with a nice green tea lotion, and then massage them with hot stones. It's almost unbelievable that you get all that for the most basic pedicure they offer. You can pick any polish color off their wall or bring in your own as well. Manicures are a pretty similar experience, and if you add one on, it will cost about $50 total. Woah. Attention‼ They offer you complimentary wine while you're enjoying your salon experience. They have red, white, and house made sangria to choose from. If I recall correctly, they have had champagne in the past on occasion. Overall, I highly highly recommend Cosmo Nail Bar. It's such an Adam's Morgan gem!

    I went in to get a full new acrylic set to fix a sloppy manicure from a different salon. I am SO impressed with the service i received! Tweety was my technician and she was extremely patient & informative. She paid very close attention to detail. The shape is perfect, they even look great from the side! I truly wish I could give even more stars!!

    Every time I'm at Cosmo's, I receive exceptional service. The ladies are very friendly and attentive. The manager, Yoyo usually takes care of me, and she knows exactly how I like my nails. I would suggest making a reservation since business fluctuates, and you may not always get the nail tech you want, otherwise. Make sure you are open to the ladies switching on and off as there are ladies who specialize in different areas! Definitely check out their new location at 1911 9th Street NW, as well!!

I sometimes felt the extensions done elsewhere were sometimes inconsistent in application and would look a bit heavy on me. Additionally, I was driving to Old Town when I live in the city and would often battle additional traffic as well as parking issues. So when I saw the fabulous reviews for Dupont Lash I decided to give them a shot. First, I was so pleased with how easy it was to book and that I was able to find availability the same week. That was challenging at the last place I went because there was only 1-2 lash techs. When I met Sara, she was so helpful in asking me what look I was going for. I showed her my past applications that were my absolute favorite as well and sharing with her the overall look I was going for. She understood the assignment immediately and nailed in on the first time. When I came back the second time I just wanted as very slight modification, and once again she executed it perfectly. (And she is so lovely!) Additionally, my lashes seem to stay on some much longer. Although I typically do a two week fill, my two week mark usually still looks so fresh and so good! Overall, I'm glad I made the switch and found a place that is more convenient and consistent.

While I've had lash extensions since November, not once did any of the techs at the other salons tell me the extension length I wanted was WAY too long for my natural lashes to support. I was having to spend tons of money each week to get a fill because my natural lashes just couldn't support the weight. Still being a newbie to extensions, I knew something didn't seem quite right with my current extensions but I just didn't know for sure. I decided to switch salons and booked a "fill from another salon" and was told to text photos of my current lashes to the Art of Lash. Within 10 minutes, Malin called me to discuss my current lashes and the possibility that they won't be able to fill on them. She suggested we re-book as a removal and full set (which is precisely what we did). When I arrived to Art of Lash for my consultation and (possible) fill, Christina sat down with me and completed a consultation before looking to the damage that had been done by other places. This is the first time I've had anyone really take me through the steps and ask me what I was looking for. She provided pictures of different shapes and before/afters of people to show the results. When I finally laid down and Christina saw my lashes, she was pretty upset. She said there was 1) WAY too much glue 2) way too much length (only 30% of your lash length max, mine were more than 50%), and then 3) multiple extensions glued together- meaning there was twice the amount of weight per lash. NO WONDER WHY I HAD SUCH A HIGH TURNOVER RATE!!! My lashes simply couldn't support the extension that were incorrectly and unskillfully applied by other salons. Of course this meant Christina had to remove my old extensions and then apply a full new set. Yes, it was a lengthy process (especially if you're not someone who can fall asleep aka me), but it was SO SO worth it. My lashes look amazing now and are much healthier with a normal turnover rate. When the appointment concluded, Christina was super helpful in giving me aftercare instructions, recommending a cleanser, and recommending I use a lash serum (since I like length & the extensions from before damaged my natural lashes). At the other two salons before this one, I was NEVER told how to clean and care for my lash extensions so this was so incredibly refreshing. Yesterday, I had my first 2 week fill. This was the first time since November I have been able to retain lashes this long and not look like a crazy person. Christina informed me my lashes were growing back in pretty well & my retention rate was awesome. Amazing what can happen when the proper length is used and care instructions are given! Art of Lash has changed my world! Moral of the story: if you're looking at reviews on here to make an informed decision, you've found your lash place. Don't risk your lash health just for cheaper prices elsewhere because this salon is 110% worth the cost. Christina is incredibly knowledgeable, skilled, and an overall kind person. The salon is gorgeous and has wonderful aftercare products for sale as well! You won't regret getting your lashes done here!

Before finding this salon in DC, there was a stretch of time, especially during COVID, when I stopped getting Brazilian treatments altogether. By the time I first came into Inari, my hair had fully reverted back to its natural state, which for me means very curly, very big, very everything. From that first appointment onward, the results have been incredible every single time. I usually go either once a year or every six months, depending on whether I want to let my curls really come back or keep things sleek for longer. The upkeep is easy, the results last, and the quality of the treatment is outstanding. One thing I have learned over the years, and this is not specific to Inari but worth mentioning, is that letting the initial treatment stay in your hair for a full 48 to 72 hours really makes a difference in how well the keratin sets. When done right, the transformation is wild. I go from extremely curly hair to pin straight hair after washing. Sometimes it is almost too straight for me, but honestly, I love it. The team here truly knows what they are doing, and the consistency over multiple years is what keeps me coming back. I will absolutely be returning again in a few months for another blowout and would recommend this salon without hesitation.

I was getting lash removal & a new set of classic/hybrid lashes. I've been getting eyelash extensions for 13 years and this is by far the worst experience I've ever had. They were thin, whispy, pre-made fans that were poorly glued onto only some of my lashes. They started falling off almost immediately, and there were visible white clumps of glue that a friend pointed out because she thought I had crumbs on my eyes. One week later when I went to another eyelash studio, they couldn't even tell I had any extensions on until they put me under the lights. I would've been better off just curling my own lashes & using mascara because mine are thicker & longer than whatever they used. I've never had such poor quality.
