This bill, titled the "Healthy Hair Act," aims to protect public health by prohibiting certain chemical substances in hair care products. It amends the Federal Food, Drug, and Cosmetic Act to specify that any hair straightening or smoothing product , including keratin treatments, containing formaldehyde or formaldehyde-releasing substances will be considered adulterated. This means such products will be effectively banned from being introduced or delivered into interstate commerce 180 days after the Act's enactment. Furthermore, the legislation mandates the Commissioner of Food and Drugs, in consultation with the Director of the National Institute for Occupational Safety and Health, to conduct a comprehensive study. This study will investigate the short-term and long-term health impacts of exposure to these substances, specifically examining effects on salon workers and potential links to cancer, respiratory issues, and endocrine disruption . The Commissioner is required to submit an initial report within one year and a final report, including recommendations for regulatory action and further research, within two years and two months to Congress.
