My hair has been dyed since 1983! All I know now is I'm sure there's more grey in there than I should have. I think the colour has given up... and really, why wouldn't it? It's been black, red, pink, green, yellow orange purple, blue.... white even. I've had a Lily Munster Mallon streak, I've had tiger stripes painted into the length with dye, I've had dreads, extensions, a mohican... all of these with waist length hair. It was royally trashed and snapped off to shoulder length, and since regrowing it I have fairly consistently had rich dark brown with a fringe or not, for the last 20 years, anywhere between mid to very long.
The most depressing part is the post pregnancy hair loss. I keep threatening to have a bob (not dissimilar to yours NIX) because it has lost so much volume but I just don't have the bottle. It just wouldn't be me.
Chapeau, my lady, chapeau. (That's David Duffield talk for hats off - oh my god I'm even QUOTING cycling commentators now)
