Hi again --
Nice to see the added pics since I posted! Shiny, your natural mix of colors looks beautiful and -- to Viva's point -- I do think many blondes end up looking like they're still highlighting and vice versa.
A blonde friend of mine stopped highlighting in her late 70s due to thinning and breakage, and whenever we get together I jokingly, say, "oh, coloring again?" because she looks almost exactly the same.
Inversely, a mid-life blonde with a teenager stopped coloring (looked amazing IMO) and then told me she started up again because she was "feeling old." But I have to stop myself from saying, "oh you went back to natural" when I run into her because her colored/natural is so similar.
Having had a zillion convos about dyeing during/after, I can tell you that the blondes and light browns always say, "oh you're so lucky to have the contrast, my grey is ugly" and the brunettes always say, "oh I could never stop, the contrast wouldn't look good and I'd look old, if I were blonde maybe" or "I couldn't handle being light-haired."
Basically when you're ready you're ready and when you're not you're not.
It took me a few years to work up to it. I finally just couldn't stand the thought of dyeing every 3-4 weeks til some TBD date. The idea of dyeing into my 70s like the women in my family felt oppressive. Plus I felt like it'd be easier to start while I was still partially brunette since that's a big part of my visual identity.
So yes, I do get a big of a shock in the mirror because hi, I'm not a dark brunette anymore haha. It'd literally be the same shock if I were a dyed redhead or blonde -- but minus the societal "Grey = Old."
ps Thank you Suz! I really thought we'd end up Hair Twins when I got done and remain a bit bummed to not have your beautiful shade, but Shevia and I are still the streakers.
