(WKBW/CNN) If you have curly hair that you like to straighten, you should be familiar with the Brazilian Blowout. Stylists and customers say it works great, but the government is concerned about its safety.

Testing on a bottle of Brazilian Blowout by OHSA, the Occupational Safety and Health Administration showed more than 8 percent formaldehyde, but the product claims it's formaldehyde-free. Formaldehyde is believed to cause cancer in humans.

Stylists and customers have complained of burning in their eyes and nose when using the solution, and now OSHA wants to learn more about the air they are breathing during the treatment.

Brazilian Blowout says the safety of its product is a top priority, and says it's now conducting a thorough investigation.
