Which procedure is NOT part of the nail technician's responsibility?

Providing medical advice is not part of a nail technician's responsibilities because nail technicians are trained to focus on cosmetic services related to nails, such as manicures, pedicures, and nail enhancements. Their education and licensure are centered around beauty treatments and hygiene, rather than medical knowledge or health assessments. Medical advice often requires a healthcare professional's qualifications, as it can involve diagnosing conditions or recommending treatments, which falls outside the scope of a nail technician's practice.

In contrast, cleaning and sanitizing tools, performing nail enhancements, and applying polish are all essential tasks that nail technicians are trained to perform. These responsibilities ensure the safety and satisfaction of clients within the nail salon environment, highlighting the importance of hygiene and skill in their daily operations.
