If you’ve spent your evenings during quarantine scrolling through TikTok like we have, then you’ve no doubt spotted the heatless curl methods that have gone viral on the platform. Gen Z content creators have been experimenting with different ways to achieve curly or wavy hair, sans the use of heat tools like flat irons and curling irons. And frankly, we love that for them.

Some of the TikTok methods are new and innovative, and some have been around and used by hairstylists for ages (fashion and beauty trends are cyclical, after all). But what these viral heatless curl methods all have in common is that they turn out amazing. However, because we know that what’s posted on social media isn’t always the whole story, we reached out to Jason Lee, award-winning stylist and owner of Toronto’s Jason Lee Salon, to get the scoop on which methods are legit and worth trying, and which ones you’re better off skipping, depending on your hair type.

Before we dive in, Lee notes that “all of these techniques require a little bit of dampness to start in order for the hair to set overnight. If you try any of these techniques on dry hair, you run the risk of nothing happening.”

Bathrobe Pigtails

“This technique works because of the size and diameter of the bathrobe belt and the fact that it’s a softer material; this will create a softer wave pattern,” says Lee. One thing that Lee notes is that this method will work best for those with fine to medium hair. “For those with naturally curly hair, this may actually stretch out your curl.” Lastly, Lee says that “if you try this technique, don’t be afraid to run a finishing product through it with your fingers to soften the sections afterwards, and a little texture spray to create an [effortless] look.”
