When I turned fifty, I stopped coloring my hair.
I saw my first gray hair when I was nineteen, which means I colored it for most of my life. My hair tends to grab brassy tones no matter what my stylist does, so now I have even given up on having a glaze applied to brighten it and lowlights to give it depth.
That decision results in once again letting the color grow off of my hair. It was probably late February the last time I saw my stylist, so the previous chrome glaze has faded. What remains is the brassy tone only in the back on the ends from the low lights of late last year.
When I decided to let my hair grow out to its natural color the first time, it was much shorter, so I got regular trims and used a temporary tint to ease the transition. My hair grows pretty fast, so I only had to deal with the transition stage for about eight months. At this length, it will take more than a year to get rid of the traces of color.
