Dry shampoos containing benzene remain on store shelves, study finds

Dry shampoos — used as a quick fix between washes — are an increasing health concern, with more of the aerosol spray-on products found to be tainted with a cancer-causing chemical, according to findings released on Tuesday.

Benzene — the contaminant behind nationwide recalls of dry shampoos by Unilever and Procter & Gamble — is also showing up in products that remain on store shelves. That includes popular spray-on shampoos including Church & Dwight's Batiste and DeMert Brand's Not Your Mother's, the new study found.

New Haven, Connecticut-based Valisure tested 148 batches from 34 brands of spray-on dry shampoo and found benzene in 70%, the laboratory stated Tuesday in a news release.
