My husband says never. But I always tell myself that maybe around 60, I’ll need to let the gray take over and stop trying to fake it. I don’t want to be one of those “women of a certain age” who walk around with an unconvincing head of jet black hair, or who combs in her eggplant-colored Fanci-Full after each wash and hopes she doesn’t sweat or get caught out in a rain shower. So I wonder, when is the right time to go gray?
