Nail salons use a variety of products that may contain chemicals that can affect worker health. These chemicals can be hazardous individually and can potentially cause even greater harm when combined. Some of the most concerning chemicals used in nail salons include toluene, formaldehyde, dibutyl phthalate, and methyl methacrylate.

The labels of all cosmetics, whether marketed to consumers or salons, must include a warning statement whenever necessary or appropriate to prevent a health hazard that may occur with use of the product. Cosmetics sold on a retail basis to consumers, such as in stores or online, must also bear a list of ingredients, with the names of the ingredients listed in descending order of predominance. However, the requirement for an ingredient declaration does not apply to products used only at salons and to free samples.

Good ventilation in a nail salon is important to eliminate the need for workers to wear heavy-duty respirator masks with organic vapor cartridges. Workplace conditions in certain nail salons can alleviate or exacerbate health issues. Studies documenting the health problems of nail technicians often describe respiratory, skin, and musculoskeletal issues.
