Forsake the shower? Dirty hair is good for the environment

Here's some interesting news I learned from The Beauty Brains: Dirty hair might save the environment. Ok, maybe that's stretching it a bit, but dirty hair is at least good for the environment because it absorbs ozone from the air. In fact, dirty hair absorbs seven times as much ozone as clean hair does. And according to scientists, this can help cut the amount of harmful ozone floating around your head. Surprising? I think so.

But, as the brains are quick to point out, this isn't going to save the world or anything. In fact, the ozone in the air can interact with oil in dirty hair to produce other harmful chemicals. Still, washing your hair too often will waste water. Instead? Try to find a balance. Or, just shave your head.
