Apple cider vinegar (ACV) is the superstar of natural hair fixes. Its mild acidity helps dissolve the mineral deposits that hard water leaves behind.
Mix one part ACV with four parts water in a spray bottle or cup. After shampooing, pour it through your hair, let it sit for 2–3 minutes, then rinse with warm water.
Warning: Your bathroom might smell like a salad dressing, but the smell fades fast. Your hair will come out shiny, soft, and squeaky clean—like it just got a spa day.
Pro Tip:
If you have color-treated hair, use a diluted rinse every two weeks. Too much acid can fade your color, so go easy—nobody wants to be a surprise blonde!
