El mejor esmalte de uñas cerca de mí en Ballston, Washington D. C.

Susan’s attention to detail and thorough work is beautiful! She was very kind and stayed late to finish my nails and this is probably the cleanest, most evenly shaped manicure I’ve ever gotten.

I arrived late for my appointment, but the staff at Cosmo Salon and Nail Spa were incredibly accommodating. Although I couldn’t recall the name of the waxer, she was exceptionally skilled, efficient, and thorough. My pain level was practically zero, and I felt completely relaxed throughout the process. She was a perfectionist, ensuring that every hair was removed, leaving me completely satisfied. I highly recommend Cosmo Salon and Nail Spa and will definitely be returning in the future. Thank you so much!

this was my first time visiting this nail salon. Anna did a great job on my Gel-X! She was so careful and precise! She took her time and even redid one that she didn’t think was quite right. I have already booked my refill appointment. Highly recommend!!!

I had the best first time experience at this salon. Very clean, welcoming, good music and the staff was very friendly. I had Soko do my nails, it was a dip manicure with tips and I paid extra for more than one color. She took her time and delivered an excellent product! I am so happy with my nails and definitely look forward to revisiting again. Highly recommend Cosmo Salon & Nail Spa!

Everyone in the salon was attentive and friendly, creating such a calm and welcoming atmosphere. My nailtech Suzan did an amazing job ( I highly recommend her !!) I got the gel x builder with non tox polish and couldn’t be happier with the result. She used sterilised equipment, worked with great precision, and made sure every detail was perfect. This is honestly the best nail set I have had in a long time and Im coming back for sure

Bella is a wonderful professional. Her skill and finesse cutting and shaping nails enhances your nails for her final touch applying polish resulting in a gorgeous finish. Bella is amazing.

All the nail technicians are so professional! I also love the color options. They even have non-toxic nail polish options. Great salon.

I love coming here. The quality of the work is high. They also use good quality nail polish and have a large selection.

Susan was super patient and meticulous. If my nails last for as long as they usually do, then I will definitely be back! Thank you!

I love this nail salon; everyone is so nice; i can't wait to come back regularly
