Because so many of us rely on the magic of dry shampoo as part of our daily routine, it’s important to know that Unilever is putting forth a dry shampoo recall for many of its popular products. The concern is that these dry shampoos may contain elevated levels of benzene—a cancer-causing carcinogen—in them.

This recall is the latest of half a dozen so far this year over benzene contamination, with the cancer-causing chemical showing up in popular deodorants, hand sanitizers and sunscreens. An internal investigation identified the benzene issue, and Unilever worked with its propellant suppliers to address the issue.

“Benzene is classified as a human carcinogen,” the FDA says in a statement. “Exposure to benzene can occur by inhalation, orally, and through the skin and it can result in cancers including leukemia and blood cancer of the bone marrow and blood disorders which can be life threatening. Benzene is ubiquitous in the environment. Humans around the world have daily exposures to it indoors and outdoors from multiple sources.”

The latest recall includes dry shampoo aerosol products made before October 2021 from brands Dove, Nexxus, Suave, TIGI (Rockaholic and Bed Head), and TRESemmé, the company said in a notice published on Friday by the U.S. Food and Drug Administration.
