TLDR Hair keratin treatments can be harmful, potentially causing health issues like skin reactions and cancer.
The document discusses the risks associated with hair keratin care treatments, particularly those known as Brazilian blow-dries, which are used to make wavy and curly hair straight and shiny for extended periods. Despite being marketed as safe, these products often contain formaldehyde or its derivatives, which can lead to various health issues. Short-term exposure to formaldehyde can result in symptoms like erythema, itching, burning eyes, and respiratory problems, while long-term exposure has been linked to more severe conditions including contact dermatitis, congenital defects, cytotoxicity in the respiratory tract, and cancer. The document emphasizes the need for increased awareness among professionals and consumers about these risks, and calls for a safety assessment of hairdressing products that considers occupational exposure, not just consumer safety. It also advocates for stricter regulation and inspection of these products and hairdressers in the market.
