While you are driving to the health food store to buy the chemical free and non carcinogenic shampoo and conditioner, don't forget to hold your breath to keep from inhaling those toxic fumes from your car, the fifty million other cars on the road and the tons of pollution being pumped into air by Dow Chemical.

I guess what Im saying is at this time and age, theres no fool proof way to avoid ingesting/inhaling chemicals. If you aint getting it in your shampoo, be certain you will be getting it one way or another.
