"It can cause your eyes to burn and probably your skin to burn," Davis said. "Absolutely. But only without the proper ventilation and the circulation of air within your salon."
Davis points to two fans running in the room. She said she's never had health problems as long as she followed the guidelines [PDF] of the Occupational Safety and Health Administration (OSHA) on proper ventilation. "So even if it has a [label saying] ‘caution: formaldehyde in it,’ basically I’m like, 'And? We already have smoke in our salons.'”
Davis notes that ethnic hair salons have used hair straightening treatments with toxic chemicals for decades. She believes the reason the FDA is now receiving complaints may be because hair-straightening treatments have become popular outside of ethnic salons. "[Ethnic salons] know all about the need for ventilation," Davis says. "My point is as white-oriented salons become more familiar with strong chemicals, they are more challenged to not overlook the ventilation issues."
But Renee Sharpe, a scientist and the California director of the Environmental Working Group, or EWG, says all salon owners should be concerned. The EWG did a study on formaldehyde in hair products and say their reports clearly show that some salon workers were having negative health effects.
"People have really different sensitivities to chemicals. So what is fine for one person may not be fine for another person. Do you really want to have a product on the market where OSHA is saying that you have to follow all these precautions? Ultimately that means that product is toxic and shouldn’t remain on the market."
Sharpe says while the EWG welcomes the California Attorney General's decision, it's only a first step. They want the Food and Drug Administration (FDA) to ban all formaldehyde beauty products. Sharpe says the EWG filed a Freedom of Information Act request to the FDA and got back scores of consumer complaints about hair products containing formaldehyde.
"We got back so many records of people complaining of nausea, of vomiting, of hair loss, of actually scalp burns, skin burns. There’s a huge volume of consumer experiences with this product that shows that this is dangerous." Indeed, these are all commonly known side effects of formaldehyde exposure.
Sharpe says EWG’s research shows that there are sixteen other companies that make hair-straightening products that contain formaldehyde, but many still claim to be formaldehyde-free. But you may find the ingredient methylene glycol, which Sharpe says is formaldehyde in solution. This was the case with Brazilian Blowout.
"People have this perception that it’s just about Brazilian Blowout when it’s really this much wider class of products," she said. "And it’s not just California, of course. This is an issue that is nationwide."
As part of the settlement, the makers of Brazilian Blowout must send warning letters to salon owners using their products, make changes to their website, and pay $600,000 in fines. In a statement they wrote, "We believe the settlement reached with Attorney General Harris represents a fair and equitable resolution."
