Oh, about looking old.........if you are tired and old looking, no amount of fake color will help you. You will just be old and tired looking with bright fake hair! Keep a smile, glow from with in and hair doesn't matter.
I turned gray at 12 years old. In high school, I could buy all the beer. I finally broke down and started coloring it on my 27th birthday. I was a dark brunette. By my mid thirties, it was white and 2 weeks after a color job, I looked like a skunk. Hmmmm time to lighten up. I became a red head...
