Apple cider vinegar can smooth the cuticle, making your hair appear smoother and shinier. It does this by balancing pH levels unlike commercial shampoos that strip the hair and leave it looking rough, dry or dull. It also removes buildup and can help with dandruff and an itchy scalp.
Simply use ACV as a rinse. Dilute it with equal parts water and dump over your head while in the shower. Give it a moment to sink in before rinsing.
