This encompasses a variety of tasks such as manicures, pedicures, nail enhancements, and nail art, which are essential parts of nail care. Additionally, nail technicians need to ensure that their tools, such as clippers, files, and buffers, are properly sanitized and maintained to uphold health and safety standards.
