Which of the following is essential for preventing infections during manicures?

Using gloves during manicures is essential for preventing infections as they act as a barrier between the skin of the manicurist and the client's hands. Gloves help to minimize direct contact with potentially contaminated surfaces and reduce the risk of transmitting bacteria or viruses. They also provide a level of protection for the manicurist, keeping their hands safe from exposure to harsh chemicals found in nail products.

Infection control is a critical aspect of nail care, and wearing gloves ensures a hygienic environment. It is particularly important when performing services that may involve cutting or filing the nails, as these activities can create small openings in the skin where pathogens could enter. Additionally, gloves help maintain cleanliness by reducing the risk of contaminating tools and products.

The other options listed do not contribute directly to infection prevention. Scented products, nail art, and nail polishing are more focused on aesthetics rather than maintaining hygiene and safety during the manicure process.
