A recent study conducted by the Silent Spring Institute has unveiled the presence of numerous dangerous chemicals in hair extensions, marking it as the most extensive research on this topic to date. Published in the scientific journal Environment & Health by the American Chemical Society, the study emphasizes potential health risks associated with a category of cosmetic products that remain largely under-regulated. Researchers analyzed 43 commercially available hair extension products, both synthetic and organic, using a non-targeted chemical analysis method (two-dimensional gas chromatography with high-resolution mass spectrometry).

The findings revealed over 900 chemical signatures, of which 169 distinct chemical substances were identified. Alarmingly, many of these substances have been linked to serious health issues, including carcinogenicity, endocrine disruption, developmental toxicity, and effects on the immune system. Almost all samples contained hazardous chemicals, such as flame retardants, phthalates, pesticides, and organotin compounds, raising significant concerns for consumers and regulatory bodies alike.

This report serves as an urgent call to action for greater regulatory scrutiny of hair extensions and similar products in the cosmetics industry. Consumers are urged to be cautious when purchasing hair extensions, as awareness of these potential health dangers comes to the forefront. The implications of this research extend beyond individual health risks, potentially influencing regulatory policies and consumer safety standards within the beauty industry in Greece and internationally.
