The people so keen on just going grey are the fortunate ones who go grey/white in an attractive manner, My DiL's family go grey evenly all over from all over iron grey, then grey then white. I envy them. See above for what happens to me.
Now, this is the strange thing. When I first stopped colouring my hair it looked like it was white all over. I, too, envied women who had the most fabulous greys. For some reason my hair started looking like it was streaked rather than white and it stopped being curly. I now wear it in a bob and my hairdresser has been asked by other clients to have the same coloured streaks! We are both totally bemused by it. Long may it last, but I suspect that it will soon start going white.
