Which statement best describes MMA usage in salons?

• A. MMA is illegal in the salon, so never
• B. They are widely approved for most services
• C. Only allowed in closed systems
• D. Allowed in the reception area

Answer: (A)

Safety and regulation around methyl methacrylate (MMA) in salon nail services is the idea being tested. MMA is widely known to pose significant health risks when used on clients, including strong, persistent odors, severe allergic reactions, dermatitis, and damage to the natural nail. It forms a very rigid, inflexible bond, which can lift or separate as the natural nail grows, making removal difficult and often leading to nail damage or infection. Because of these hazards, regulators in many jurisdictions ban the use of MMA in consumer nail services and require safer alternatives, such as ethyl methacrylate (EMA), for professional nail products. Given these safety and regulatory concerns, the statement that best describes MMA usage in salons is that MMA is illegal in the salon, so never. The other options contradict established safety standards and regulatory practices, as MMA is not broadly approved for salon services, is not allowed only in some restricted “closed” systems, and certainly is not permitted in common areas like the reception area.
