Greasy hair protects against ozone gas

If you plan on going to Lollapalooza this summer, plan on seeing some of the healthiest heads of hair on the planet. That's because having greasy hair can actually protect your lungs from ozone gas.

Scientists from the University of Missouri discovered that greasy, unwashed hair absorbs seven times more harmful ozone gas than clean hair. This is great news for the lungs of Radiohead fans with mop-tops; when hair traps more ozone gas, less is breathed in.

Peak concentrations of ozone gas are now far higher than the pre-industrial levels and even background concentrations -- well away from sources of pollution -- are substantially higher. In short, you may want to hold off on getting that summer crew cut. At least until after going to the concert.
