Dirty Human Hair Neutralizes Ozone

By | July 16, 2008

Don’t feel like washing your hair today…No worries, it’s ok, you’re helping the environment.

That’s right, oily, unwashed hair can destroy dangerous pollutant ozone. Scientists at Missouri University of Science and Technology discovered that dirty hair absorbs seven times more ozone than clean hair.

I know what you are saying…absorb the ozone? But I thought we needed to protect & save it.

According to the EPA, ozone is a gas that occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be “good” or “bad” for people’s health and for the environment, depending on its location in the atmosphere. In the troposphere, the air closest to the Earth’s surface, ground-level or “bad” ozone is a pollutant that is a significant health risk, especially for children with asthma. It also damages crops, trees and other vegetation. It is also a main ingredient of urban smog.

Ok, so how does not washing my hair actually helps the environment?

The explanation is strictly chemical: The oil in our unwashed hair and skin contains double-bonded molecules, including triglycerides, fatty acids, and a substance called squalene, that latch onto the ozone (O3), neutralizing it before we have a chance to breathe it in.

Unfortunately, though, it’s not without its drawbacks. The absorption process causes by-products like formaldehyde and other irritants.
