Garnier Fructis Anti-Frizz Serum, Sleek & Shine

L'Oréal's Garnier Fructis Sleek & Shine Anti-Frizz Serum is proving too hot to handle.

Following claims that the beauty brand neglected to warn consumers of the hair product's flammibility, California District Court Judge Christina A. Snyder has given the go-ahead for a class-action lawsuit to move forward, Women's Wear Daily reports.

The class certification means that any shopper who purchased the serum from February 4, 2008 to the present—during which time 9.9 million units are said to have been sold in the U.S.—may join the original lawsuit filed by plaintiffs Jill Guido and Catherine Altamura of California, Natalie Lefebvre of Texas, and Lisa Pearly of New York.

The lawsuit charges that L'Oréal put customers at risk by failing to label the serum as "combustible or flammable near flame, ignition, or high-heat-producing styling appliances." Court documents also allege that the brand led consumers to believe that the product was safe to use with heated hair tools such as straighteners.
