The hair of the dog isn't just for hangovers-- it can help your garden and ease pollution too!

For a closer look, KCBS news anchor Holly Quan spoke with Lisa Gautier, founder of Matter of Trust, an ecologically focused group in San Francisco, who has been using hair for decades to clean up oil spills and other pollution from bodies of water.
