Apple cider vinegar may be used as a hair rinse. Dilute it to at least one part water, one part vinegar, and massage the mixture into your hair after washing with shampoo.
Apple cider vinegar contains acetic acid that helps remove product build-up on hair. Avoid using undiluted vinegar on your hair, as the high acidity may cause damage. The vinegar is created by using yeast to ferment apple sugars into alcohol, which bacteria then use to produce acetic acid. Unfiltered vinegar retains the bacteria. Apple cider vinegar is often used in traditional medicine as an antibacterial, skin exfoliator and weight loss aid.
