Highest quality Lash service I've experienced. Been going to Cosmos Salon & Spa for "Classic Full Set" lash extensions over past 3 years taking 6 month breaks. I've always booked with "Alley", she is absolutely meticulous! Treatment room within the upbeat Salon is clean and relaxing. Follow instructions of proper lash care and Alley's application of lashes look full for close to two 1/2 weeks. Alley is professional, kind, always on time - always a 5 star-service. Dates of Most Recent 2025 Service: 11-21-25; 11-11-25 & one booked for tomorrow. I've booked an estimated 30 appointments with Alley over the past 3 years - always consistent excellent service. Front desk is friendly & helpful. Tip to Owner: Add a category your GBP "Google Business Profile" for "Lash Extensions" would help to get found via AI SEO. It's next to impossible to find quality Lash Extension services and Cosmos is best I've come across.

This was my first visit to Cosmos. I saw Erica for a full highlight and cut and she did amazing! I usually keep my expectations low because my hair rarely turns out as blonde as I want, but Erica made it happen! So happy with my hair and will definitely be back.
I’m so impressed with Lily ! She exceeded my expectations and was very thorough. I was advised to pick another stylist since she hadn’t had much experience with balayage. But let me tell you .. Lily Nailed it ! I’m so glad I gave her a shot and had full confidence in her. Amazing work 10/10
I had a wonderful time at Cosmos. They're all friendly, but my stylist Devyn was a true gem. She gave me a shampoo that was so good I was ready to fall asleep. She styled my hair with care and ingenuity. She colored my hair perfectly. I am so happy I got to have her. She's a gem. I highly recommend Cosmos and Devyn
I had such a great experience at Cosmos Salon and Spa! Sarese did my hair and she was AMAZING! Seriously listened to what I wanted and absolutely killled it. The front desk was so welcoming from the moment I walked in, and the salon itself is beautiful. Everyone I interacted with was so kind and made the whole experience feel easy and relaxing. I would 1000% recommend and will definitely be back! Thank youuu Sarese 🫶🏼
