2025-12-17I am obsessed with this set! I came in with a vision for a 'coquette-meets-cyber' look, and they absolutely nailed it. The 3D bunny detail is so cute and perfectly sculpted, and the chrome heart accents give it such a cool, modern edge. The hand-painted bows and cherries are incredibly precise. If you want high-quality nail art that actually looks like the inspo photo (or better), this is the place to go. I’ve been getting compliments all day!

2025-11-01Cosmo Lux Nail Salon is absolutely incredible! From the moment you walk through the doors, you’re treated like royalty. The staff is beyond friendly, professional, and genuinely cares about making sure you feel pampered and relaxed. The atmosphere is elegant and spotless — it truly feels like a luxury spa experience right here in Fairwood. Every service I’ve had, from manicures to pedicures, has been flawless. They pay close attention to detail and go above and beyond to make sure everything is perfect. You can tell they take real pride in their work and love what they do. I’ve never felt more comfortable or more taken care of in a salon. If you’re looking for a place that combines luxury, warmth, and perfection, Cosmo Lux is it. I honestly wish I could give them more than 5 stars — they deserve 10! Thank you to the entire Cosmo Lux team for always making me feel special and beautiful every single time. 💅✨

2025-10-27Love my nails today! Great environment, clean spotless. Jade was my nail technician. She helped me choose a lovely color - TAP gel Tie the Knot and a fun pumpkin color for Halloween. Jade was friendly and professional. Thank you, Jade! 😍

2025-09-13I've been coming here for years and have always had great service with everyone, but wanted to take a moment to share these Spider-Man nails that Kathy did for me today. She has a real eye for detail and perfection and I'm so happy with how they turned out!
