The smoke from burning hair during a laser hair removal treatment could be bad for you and worst for those who are regularly exposed to the smoke as it contains chemicals that irritate the airways and are known to cause cancer, the Daily Mail reported.
Dr. Gary Chuang of the University of California, said, "Laser hair removal performed by improperly trained personnel or in an inadequately equipped facility will put both the healthcare workers and patients at risk." He added that the procedures should only be performed in spaces with an adequate air filtration system and a smoke evacuator.
‘The smoke from burning hair during a laser hair removal treatment contains chemicals that irritate the airways and are known to cause cancer.’
The team collected hair samples from two volunteers, sealed the samples in glass jars, treated them with a laser and captured 30 seconds of laser 'plume'. They identified 377 chemical compounds in the smoke, including 20 that are known environmental toxins, such as carbon monoxide, and 13 that are known or suspected to cause cancer.
The researchers conclude that the burning-hair plume released during laser hair treatment should be considered a 'biohazard, warranting the use of smoke evacuators, good ventilation, and respiratory protection'. The study is published in JAMA Dermatology
