Which substances are prohibited in the practice of cosmetology in Nevada?

The correct answer identifies methylene chloride and certain toxic chemicals as substances prohibited in the practice of cosmetology in Nevada. Methylene chloride is a solvent that is often found in paint strippers and is known to pose serious health risks, including respiratory issues and potential carcinogenic effects, which makes it unsafe for use in any cosmetology practice. Additionally, the regulation against certain toxic chemicals protects both the clients and the practitioners from harmful exposures.

Regulatory bodies like the Nevada State Board of Cosmetology enforce these restrictions to ensure a safe environment for both professionals and the public. Keeping toxic chemicals out of salons minimizes health risks associated with inhalation, skin contact, and other exposure routes during various cosmetology services, such as hair coloring, nail care, and skin treatments.

While other substances listed might be common in cosmetic products or treatments, they do not carry the same level of health concerns that warrant prohibition. Therefore, understanding which substances are regulated helps practitioners comply with safety standards and remain compliant with the law.
