Like others, my family tend to retain their hair colour in old age. My father died at 82, with hardly a grey hair on his head. I'm 63 and have never dyed my hair, as it is still the original red. Albeit it is a nicer colour, as it used to be carrot orange, ? when I was a child. ?♀️
However, my very dark haired daughter went grey in her twenties.☹️ I do have a cut and blow dry every 5 weeks, as it is so thick and grows really fast.
I'm very lucky that is many different shades, people at work often commented on my " highlights", which were actually my own colour.?
