My hair started going white before I was thirty, and I've lived all my life in that speckled state of transition; but now it is properly white all over, and there's still lots of it, thank goodness ... and I've never dyed it, and don't plan to. That's the hair on my head!
But the hair elsewhere ... well that's taken longer to turn, but it's turning now, and I don't fancy that with thick strands of grey and white in it. For a while I shaved it off, but I'm back to liking it again, but not the colour ... so I'm dyeing it ... I've tried auburn and chestnut but I prefer a really dark reddish brown ... now I've really got something to look at in the mirror! :D
