SKIRMISHER

The dangerous pollutant ozone, it turns out, is destroyed by hair and body oils, an oddity revealed when researchers at Missouri University of Science and Technology compared washed and unwashed hair. Environmental engineer Glenn Morrison and physician Lakshmi Pandrangi found that dirty hair—generally awash in skin oil—consumed seven times more ozone on average than did clean hair. The explanation is strictly chemical: The oils covering our bodies contain double-bonded molecules, including triglycerides, fatty acids, and a substance called squalene, that latch onto the ozone (O3), neutralizing it before we breathe it in.
