Back in the 1970s, a woman's hair routine lived in her bathroom cabinet, not her shower shelf. No blow dryer. No serums. No leave-in conditioners. Just patience, kitchen ingredients, and fifteen tricks that kept hair healthy, shiny, and strong without spending a fortune.

These are the forgotten hair habits American women used from the start of the decade through the end, rules so simple they disappeared the moment the beauty industry decided to sell them back to us in bottles.

Which one did your mother actually use? The apple cider vinegar rinse? The beer? The egg? The silk scarf at night? Leave it in the comments.
