" Yesterday, the US Department of Labor&amp;#039;s Occupational Safety and Health Administartion (OSHA) issued a hazard warning to workers and owners of hair salons to alert them that formaldehyde, a known caricinogen, can be released into the air from keratin treatments that claim to be formaldeyde-free. Here at the Good Housekeeping Research Institute we tested 4 of these treatments for our March 2011 GHRI Investigates column and found that they all contained formaldehyde. Our advice: Avoid keratin treatments whether you&amp;#039;re a salon worker or just a salon-goer who wants straight shiny hair. For super-sleek tresses try a flat iron like the Remington Style Therapy Frizz Therapy ($50), which did well on GHRI tests.
