"But experts from Silent Spring Institute have now discovered several 'chemicals of concern' in these additions - including those made from human hair. In their study, the team screened 43 popular products sold online for a wide range of chemicals. Their analysis uncovered traces of dozens of chemicals, including flame retardants, phthalates, pesticides, styrene, tetrachloroethane, and organotins. Worryingly, previous research has shown that these substances are linked with cancer, hormone disruption, developmental problems, and effects on the immune system."
"'Companies rarely disclose the chemicals used to achieve these properties, leaving consumers in the dark about the health risks from prolonged wear,' said Dr Elissia Franklin, lead author of the study. 'The fibers sit directly on the scalp and neck, and when heated and styled, they can release chemicals into the air that wearers may breathe in.' Whether it's clip-ins, tape-ins, weaves or micro-links, hair extensions are now exceptionally popular in both the UK and US."
Analysis of 43 popular hair-extension products found traces of dozens of chemicals, including flame retardants, phthalates, pesticides, styrene, tetrachloroethane, and organotins. These substances have been linked with cancer, hormone disruption, developmental problems, and effects on the immune system. Many extensions are made from synthetic polymers or bio-based materials such as human, banana, or silk fibers. Fibers sit directly on the scalp and neck and can release chemicals into the air when heated or styled, creating potential inhalation exposure during prolonged wear. Companies rarely disclose chemical treatments used to achieve desired properties. Little research exists on the overall chemical makeup and long-term health risks.
