Shirley Nail offers a mixed experience for customers. Many appreciate the skills of specific technicians, like Jolie and Kevin, who provide excellent service and personalized care, ensuring strong and healthy nails. However, some customers have faced issues with the longevity of their manicures, with gel nails lasting only a week. Additionally, there is a requirement to bring personal nail files or purchase them on-site, which has been noted as an inconvenience. Overall, the quality of the service appears to vary based on the technician chosen.
