OAKLAND, Calif. -- An Oakland watchdog group wants you to know what's in your shampoo because it could be harmful to your health.
The Center for Environmental Health is filing suit against Walgreens and others for allegedly manufacturing or selling shampoos and soaps without labels warning consumers that they contain high levels of Cocamide DEA. That substance was listed as a toxic substance by the State of California last year.
The four companies sued Tuesday did not immediately respond to requests for comment. The group says it plans to sue 100 more companies.
