If you've ever found yourself sporting a sprinkle of 'shoulder snow', this dandruff-busting beauty hack could be for you.
It's apparently not the first time the strange trick has done the rounds online, but it's become popular again by an Instagram video from Canadian beauty blogger Farah Dhukai.
In the short video, the blogger shows her 608,000 followers that a dandruff-free scalp could only be a quick Listerine rinse away.
In the caption, she says to fill a spray bottle with half Listerine and half water, give it a good shake, and spray the mixture onto your scalp after shampooing and conditioning your hair.
