I agree. As a now elderly lady who has successfully brought up 4 now very adult children, I never had to deal with all this. I just plodded on, made lots of 'mistakes' I guess, but got there.
I colour my own hair with a semi permanent colour, easy and cheap. I have very long hair, middle of back. I'm mid 70s, and define myself, rather pathically possibly, as the elderly lady with long dark hair. I do not intend to go grey for the foreseeable future, as I explained to my daughter who asked if I would.
