Sometimes change is instantaneous. I watched Food, Inc., and immediately started buying pastured meat, milk and eggs from local farms. I never looked back. With other things, for some inexplicable reason, I’ve been slower to clean up my exposure to potentially harmful chemicals. Personal care products are a case in point. I’m good with soap, shampoo, and laundry detergent since I make my own. Sometimes I even make toothpaste. But I had been dyeing my hair for years and refused to let myself think about what the ingredients were doing to me. Just about a year ago, though, I stopped and let my hair go gray. And it’s ok. I think I even like it.
