Objective:

To identify and characterize the chemical composition of popular hair extensions and assess significant health risks associated with their use.

Approach:

Key Findings:

• Nearly all products contained at least one chemical of concern, including flame retardants and phthalates.
• More than 900 chemical signals were detected, leading to the identification of 169 compounds.
• Forty-eight identified chemicals are on major hazard lists, including carcinogenic and endocrine-disrupting substances.
• Organotins were found in about 10% of products, sometimes exceeding EU health limits.

Interpretation:

The presence of hazardous chemicals in both synthetic and bio-based hair extensions indicates that fiber origin does not predict chemical content, raising significant concerns about health risks for users.

Limitations:

• The study does not assess the long-term health effects of exposure to these chemicals, which is crucial for understanding potential risks.
• The sample size may not represent all hair extension products available in the market, limiting the generalizability of the findings.

Conclusion:

The findings highlight significant health risks associated with hair extensions, particularly for Black women, emphasizing the urgent need for industry reform and regulatory changes to prioritize consumer safety.
