Dandruff is one of life’s greatest annoyances. Not only does it limit our clothing color options, but it’s also a hassle to treat without causing further damage to our tresses. Which is why our ears perked up when we heard about this admittedly weird at-home trick.
What you do: Pour equal parts water and mouthwash into the spray bottle and give it a good shake. Next, hop into the shower and wash your hair as you normally would. Spray the mixture directly onto your scalp only. (The tingly concoction is, as you can imagine, too drying for the rest of your hair.) Let it sit for a few minutes and finish with a thorough rinse.
Why it works: Listerine has antiseptic and anti-inflammatory ingredients like menthol and eucalyptol in it that--in addition to killing germs in your mouth--can help soothe a dry, itchy scalp and the flakes that come with it. Wacky? Lil' bit. Effective? Absolutely.
