Can Greasy Hair Protect Your Lungs?
March 20, 2008
Greasy hair might reduce the amount of ozone you breathe in. When researchers exposed samples of washed and unwashed hair to ozone for 24 hours, they found that the unwashed hair absorbed around seven times as much ozone.
Ground-level ozone can cause respiratory problems, and it has been associated with increased mortality. Having greasy hair could reduce your ozone exposure.
However, unwashed hair samples did produce more secondary-reaction products created from the interaction between ozone and hair oil.
