The staff are very kind and knowledgeable. I highly recommend the builder gel for a gel polish look while helping to repair damaged nails!

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!

Amel did an AMAZING job with the hair and the owner Hannah is also super sweet and kind. Great energy there. Thank you Amel for taking your time on my hair on my keratin treatment, haircut correction from the last lady )that did my hair at at a different salon), recommended wonderful advice to promote hair growth & genuinely caring about my hair so much to ensure that I loved it and taking pix in different lighting, asking if I wanted to look at it in a different light. She truly cares about Hair and is just such a wonderful person! So glad that I finally met a hairstylist that I can trust!!!

Thank you so much, Linda! You did an amazing job with my hair. You were so patient, kind, and professional — I really appreciate all your effort. I absolutely love the result!

I enjoyed my experience from start to finish. Ta.mmy an Vivian were great.

My technician had so much attention to detail which I appreciate!

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

Lovely clean inviting nail salon with a ton of other quality services. Got a hair trim, blow out, and small wax, very pleased!

susan does such an amazing job, i can’t recommend her enough!

My daughter and enjoyed our mani/pedi! Thank you

I decided to try out this salon since it’s walking distance from me, and it was the best decision I’ve made this year! Tammy was my nail tech and made sure I walked out with the best looking mani and pedi I’ve had in a long time! I’ve gotten so many wonderful compliments! Thank you so much for transforming my nail experience into one of the best! I will definitely be returning.

I had Susan do my builder gel refill today and so so happy with my nails! Sincerely appreciated her attention to detail and taking time to make sure all my nails were even and consistent in length, shape, and thickness.

This was my first time visiting this location and the only thing that’s upsetting me is that I didn’t swing by here sooner! The nail technician was so meticulous and did an amazing job. I was there for three hours because I got multiple services and I definitely left extremely relaxed and happy with the final Look.

Susan did great! Thank you!

Cosmo does a great job with everything they do.
