Are Hair Straighteners Toxic?
There are do-it-yourself hair straighteners and there are those done at the hair salon. Hair straighteners are increasingly popular.
Do hair straighteners contain formaldehydes?
A study of leading “Brazilian-style” hair straighteners that included 45 manufacturers has found that many brands claiming little or no formaldehyde actually contain significant levels.
The study, by the Environmental Working Group, included a review of 47 adverse event reports that have been filed with the United States Food and Drug Administration. The study found that “15 of 16 companies claim little to no formaldehyde but tests show their products contain substantial amounts.” Tests concluded that some hair straighteners have up to 11.8% formaldehyde.
In addition, salon air fume testing conducted during 2010 found that hair salons often maintain high levels of formaldehyde. The researchers noted that solutions containing over one percent formaldehyde will produce significant air vapor formaldehyde levels. U.S. federal law calls for salons to provide medical monitoring and emergency wash stations if they use formaldehyde solutions over 1%.
The EWG petitioned the U.S. FDA to take action on what they cite as hazardous products.
Meanwhile, many hair straightener fans are discovering natural black castor oil, which has been reputed (but not confirmed by research) to be a healthy hair straightener. Black castor oil has also been reputed to stimulate hair growth and yield a healthy scalp.
