A new study finds that shampoo and conditioner, even the cheapest brands, are not safe from the dumping problem.

The study, released Wednesday, found that some brands have a lower risk of contamination than others, and it found that washing hands with soap is the best way to avoid contamination.

Researchers found that the most common chemicals found in shower cleaners, including chlorine, ammonia and ammonia trichloride, are in the shampoo and body lotions, according to the study.

Shampoo contains about 80 chemicals.

The other ingredients are often found in body lotion, shampoo and a few other products.

The researchers also found that most consumers have a negative reaction to some of the cleaners they use, such as hydrogen peroxide, which can irritate the eyes, nose and skin.

Researchers said the problem is particularly problematic in areas with poor water quality, like parts of China, Southeast Asia and the Caribbean, where water is contaminated by sewage and other pollutants.

The results of the study, conducted by researchers from the University of British Columbia and University of Adelaide in Australia, are published in the American Journal of Public Health.
