This hack went viral on TikTok by hair and beauty creator Jonathan Monroe when he shared a jaw-dropping video that racked up nearly 3 million views. In the clip, Monroe places a strand of hair into a soda can that looks to have the top part cut off. He moves the can up in small circular motions until it touches the root. Monroe then heats the can with a blow dryer, moving it up and down from the top of the can to the bottom. Once he slowly releases the can, he reveals a gorgeously bouncy curl.

Other social media influencers tried this hack and gave it a thumbs up, which can be viewed by searching for the hashtag #SodaCanCurls on TikTok. The strange thing is, it makes total sense once you discover how it works! As New York City-based colorist and Matrix hair educator Nicole Rolleri told Allure: “The reason this works is due to the heat hitting the can with your hair in it. The hot air is blowing in one singular direction, the same way it would blow to activate a curl with a hot tool.” Huh, who knew?
