Hair Straighteners May Not Be Good After All
Formaldehyde that binds keratin to hair is used in hair straightening products. Dangerously high levels of formaldehyde were found in the air of salons using these hair-straightening products during the investigation by the U.S. Department of Labour's Occupational Safety and Health Administration (OSHA). OSHA was responding to complaints from workers. Even products that were labelled as 'formaldehyde free' were found to contain the chemical. Evidence of allergic reactions such as eye irritation, nose bleeds was found in workers exposed to formaldehyde.
Salons and other employers, such as beauty schools, that use hair smoothing products that contain or may release formaldehyde are supposed to follow the requirements of OSHA's 'formaldehyde and hazard communication standards'. Citations and fines were issued by OSHA to salons and other employers (e.g., beauty schools) who were found to violate norms.
Formaldehyde, a strong foul-smelling gas, is a known cancer causing substance. Hair smoothing products may contain formaldehyde dissolved in water. The chemically reacted form is called methylene glycol.
Hair smoothening products release formaldehyde when heated, viz., flat-ironing or blow-drying.
Exposure to formaldehyde can occur in the following ways:
• Breathing it in through your nose and mouth
• Getting it on your skin
• Getting it in your eyes or mouth
Symptoms caused by exposure to the chemical include:
• Eye irritation and damage, including blindness.
• Nose irritation, including bloody noses.
• Skin sensitivity, rashes, and itching.
• Breathing difficulties, such as coughing and wheezing.
Formaldehyde levels above 0.1 ppm in the air can irritate nose, throat, and lungs. Higher levels worsen symptoms.
It is important that employers and employees know the risks of using formaldehyde containing products. It is not however easy since most products never list their ingredients. Products that contain formaldehyde, methylene glycol, formalin, methylene oxide, paraform, formic aldehyde, methanal, oxomethane, oxymethylene or Chemical Abstract Service Number 50-00-0 are not recommended by OSHA.
