Apple cider vinegar can totally replace your dry shampoo—here’s how

Everyone may have different philosophies on how often to wash your hair—ranging from the daily rinse advocate to those who can go 10 days without shampoo—but one thing’s for sure: dry shampoo is one of the best beauty inventions of all time (can I get an amen?).

According to French hairstylist Christophe Robin, who has a salon in Paris and treats the manes of Tilda Swinton and Catherine Deneuve, that’s not the only thing that can save your semi-dirty tresses on days you’re not washing. In an interview with the New York Times, he reveals that a certain anti-inflammatory kitchen staple can do the trick: apple cider vinegar.

“Unlike dry shampoo, there’s no residue, and the vinegar is a wonderful tonic for the scalp,” says Robin, who believes that dry shampoo should only be used to spruce up your hair for the evening or for one extra day.

You may be wondering how an ultra-sour (not to mention smelly) vinegar could possibly make your not-so-fresh tresses look good. The thing is, you don’t put it in pure form directly onto your locks—Robin says to add five drops to five ounces of water in a spray bottle, spritz at the roots, and you’re good to go. This will remove oil and give you an instant good hair day.

Next time you’re meal-prepping that dressing for your salad, you might as well pour yourself a hair tonic too. Brilliant.
