    Cosmo Nails is under new management, and I had such an amazing experience! 💅❤ Everyone was so kind and welcoming, my nails turned out absolutely perfect, and my pedicure was amazing. The new management is doing a wonderful job—definitely worth checking them out! ✨

    So happy with my experience with Jenny at Cosmo Nails today! As soon as we walked in the shop it was bright and clean and we were greeted immediately. My mom had a wonderful spa pedicure while I had a builder gel fill manicure. This was our first experience here because I live out of town but my mom will be back and so will I when I visit. Jenny was so kind and thorough with my service 10 out of 10

    I've only been here technically twice; however, my second visit was a return trip because my gel polish was peeling badly after just five days. Why the five-star review, you ask? Well, my first trip was under a different owner altogether. The new owners and staff did a wonderful job taking care of me and cleaning up the mess from the other staff, and my nails look fantastic. If my nails didn't currently have house paint on them, I'd show you. Even after almost a month, they still look great... natural French... okay, I'll show you. In the photo, you can clearly see the before and after and the quality of their work. And I'll definitely return. Thanks to the new staff.
