My mother rinsed my hair with vinegar when I was a child, in the 1950's. And her mother rinsed her girls' hair with vinegar (my red headed aunt), and lemon juice (my blonde mother) when they were little, in the 1920's/30's. Grandmother must have felt that there was a difference (maybe because of the color), and felt that lemon juice was better for blondes. I was a red head, so I got vinegar
