Skin cells produce small amounts of hydrogen peroxide as part of the body's oxygen cycle. The chemical serves to kill bacteria.

Scientists are hopeful there may be a way to remix the chemical soup to keep color in our hair, which no doubt is of interest to a hair-care industry that will be worth about $42.5 billion worldwide by 2010, according to a market report published last year by Global Industry Analysts.

Weissmann predicts it won't be long before products to remove hydrogen peroxide from the hair -- and the body in general -- are created.

"The rule goes when basic science is discovered it is quickly followed by a product," he said.
