At this point, we expect everything about the Kardashians to be sparkly and glamorous. It's hardly surprising when Kourtney uploads a selfie and her impossibly shiny hair practically blinds us through our iPhone screens. But it is startling to find out her secret to locks that gleam is just five bucks—and, you probably already have it lying around in your pantry.
The eldest sister took to her app to divulge her secret, confessing she uses apple cider vinegar to get the job done. We tested the all-natural product for its known de-bloating, toning, and brightening properties as well as its color-reviving effects (it's meant to remove hair color–dulling residue and close strands' cuticles). Turns out, Kourtney is totally right—the solution left our editor Lindsey's hair gleaming.
As Kourtney explains, "I mix two tablespoons of apple cider vinegar with a big glass of water and drink this mixture twice a day. I also use apple cider vinegar as a shampoo to clean my hair every so often. Using apple cider vinegar will naturally balance your hair's pH levels and leave your hair actually clean and super shiny."
So there you have it. It's time to jump on the ACV train once and for all.
