It's interesting how we each treat the going grey thing differently.
I had very dark hair with pale skin, never used to tan.
Started going grey when I was 21 but the contrast of the grey looked more like highlights, apparently.
I did have a semi permanent (is this the right expression?) colour for about 8 years but stopped when I retired and moved to New Zealand.
I'me happy being grey, it's a sort of pewter colour which looks ok. Anyway, it's just the way I am.
Mind you, I'me very particular about the style of my hair. Which, strangely enough is one suggested by OH, despite that, it works

An addition to the never tanning bit.
When I was about 25 I was crewing on a yacht in Greece and was there for about 3 weeks. I was desperately trying to get a tan, only to be asked by people if I was trying to keep out of the sun

At the end of the 3 weeks, overnight, I went a dark mahogany colour!
