Which of the following is NOT a service provided by nail technicians?

The correct answer pertains to the range of services traditionally offered by nail technicians within the beauty and personal care industry. Nail technicians are specifically trained to focus on the care and aesthetic enhancement of nails, which includes polishing fingernails, cosmetic care for the hands and feet, and trimming toenails. These services are integral to nail care, emphasizing skill in manicure and pedicure techniques.

On the other hand, applying hair dye is a specialized service typically performed by licensed cosmetologists or hairdressers, who have undergone specific training in hair care and coloring techniques. This distinguishes it from the scope of practice of nail technicians, who do not engage in hair dye applications as part of their professional services. This clear delineation of responsibilities helps to ensure that clients receive the appropriate care from specialists trained in each specific area.
