Illinois Nail Technician Practice Exam

On which part of the body can disinfectant NOT be used?

1. The scalp

2. The body, hair, skin or nails

3. The face

4. The hands

The correct answer is: The body, hair, skin or nails

The correct answer highlights that disinfectants should not be used on the body, hair, skin, or nails. This is because disinfectants are formulated with potent chemicals designed to eliminate pathogens on surfaces and are not meant for human skin or hair. Disinfectants can cause irritation, allergic reactions, or other adverse effects if applied to body parts that are sensitive or absorbent, particularly the skin and hair. Furthermore, the FDA and health organizations specify that certain products are approved only for use on non-porous surfaces, emphasizing the importance of using appropriate individual disinfectants or antiseptics that are specifically formulated for skin when necessary. In contrast, while disinfectants may be applied to hard surfaces carefully and effectively, they should never come into contact with the face or scalp, as these areas are particularly delicate. Generally speaking, the use of disinfectants is highly regulated, ensuring the safety of clients receiving nail technician services.
