Mine used to be blonde but turned white when I hit 36, twenty two years ago. Still a full head too and long enough to pass my shoulders.
Up until a couple of years back... well probably about 6 now [when I was 52], my hair was 3 parts the way down my back... and if my fringe was brushed forward it came past my chest. At the end of the day, however, I got it cut short because the maintenance became a bit much due to arthritis and neck pain.
I have a few grey ones on the sides these days, but for the most part it's still a browny colour... without having to dye it.
