I constantly colored or highlighted my hair in my teens, 20s, and 30s. Now that I'm in my 40s, I no longer do it, and my reasoning is probably a bit weird. My hair went from orange (talk about a natural redhead!), to strawberry blond,(ginger to the Brits), to dirty blond, to auburn, to brown. I have very little gray, which drives my sister, who went from completely black to almost fully gray at age 30, absolutely batty. Most of my friends color their hair now. I figure my hair is going to go through a few more curious color changes, and I don't want to miss them, so I'm now "going natural". I am contemplating coloring my eyebrows - they're gray, which looks strange with my hair color. My mom's cousin is 83, and always liked gray hair. She started out as a dirty blonde, as did my grandmother, and their hair turned very dark brown, almost black, as they aged. I'm curious to see whether that's going to happen to me.
