A recent study published in the Environment & Health journal has raised fresh concerns about the safety of wigs, braiding hair and hair extensions. Researchers found that some of these popular beauty products contain chemicals commonly used in industrial materials such as pipes, pesticides and floor tiles.
The study examined several widely used hair products and detected hundreds of chemical compounds. Among them were flame retardants, phthalates and pesticide-related substances — chemicals that have been linked to hormone disruption, respiratory irritation and increased cancer risk. Alarmingly, many of these substances were found even in products marketed as “safe” or “non-toxic.”
Because wigs and extensions are often worn for long periods and sit directly on the scalp, experts say there is concern about prolonged exposure, especially when heat styling is involved. While the research does not prove that these products directly cause illness, it highlights gaps in safety testing and ingredient disclosure within the hair and beauty industry.
The findings also raise important health equity questions, as these products are widely used by Black women and girls, potentially leading to higher exposure over time.
Experts advise consumers to take simple precautions, such as washing hair extensions before use, limiting continuous wear, and choosing brands that clearly disclose their ingredients. As awareness grows, calls are increasing for stronger regulation and transparency to ensure that beauty products are truly safe for everyday use.
