New study warns of health risks when applying heat to treated hair – Metro World News Brazil

A recent study conducted by American Chemical Society (ACS) Highlights the potential health risks of applying heat to hair treated with products such as creams and oils. Published in the magazine Environmental science and technologyThe research warns of the release of chemicals, especially silicones, which can be harmful when inhaled.

Detailed study and realistic simulation

To conduct the research, scientists replicated common hair care environments, such as home bathrooms, in a small, well-ventilated space. Participants applied hair products, such as creams and sprays, followed by heat treatment to straighten or curl the strands. By measuring real-time emissions of volatile organic compounds (VOCs), including silicon, the researchers observed rapid changes in the chemical composition of the air, which were exacerbated during the thermal modeling process.

Differences in emissions and the need for additional studies

The study revealed differences in emissions depending on product type, hair length and styling tool temperature. Longer hair and higher temperatures resulted in the release of greater amounts of VOCs. Silicon has been identified as the most abundant material. It is estimated that users of these products and heat styling techniques can inhale up to 20mg of D5 silicone. Researchers now emphasize the urgent need to conduct long-term studies to evaluate the potential effects on human health of silicon exposure.

Conclusion and call for future research

In conclusion, the ACS study highlights the concern about inhaling toxic substances when styling heat-treated hair. The call for additional studies highlights the importance of understanding the long-term effects of these exposures on human health. The research raises questions about common hair care practices and highlights the need to raise awareness about the potential risks associated with them.
