Federal OSHA and State OSHA programs continue to investigate complaints from stylists and hair salon owners about exposure to formaldehyde while using hair smoothing products. OSHA has conducted air sampling at multiple salons and found formaldehyde in the air when stylists were using hair smoothing products. Some of these products were labeled “formaldehyde free” or did not list formaldehyde on the product label or in the Material Safety Data Sheet (MSDS). In most cases, where the label did not state that the product had formaldehyde in it, OSHA found that hair salon owners using those products did not know that hair smoothing products contain or could expose workers to formaldehyde because manufacturers, importers, and distributors did not include the correct hazard warnings on the product’s label or MSDS.
