TikTok Is At It Again With A Voluminous Hair Hack That's Almost Too Easy

Most people will relate to the pain of trying and trying to get volume into your hair only to end up with it laying flat. Thanks to TikTok, those days of furiously adding mousse to your hair might be over.


When scrolling through the video-sharing platform, it's hard to avoid videos claiming to have the latest hair trick or hack. The popularity of these videos comes from the fact that many are looking for ways to add volume to their hair. This topic is in such demand that the phrase "How to give volume to roots" currently has a total of 3.1 million views on TikTok.

For those with fine hair, where it's harder to naturally get volume, a video posted to TikTok in March 2022 might be the answer they need. The best part of this hair hack is that it involves no extra product or hairstyling tool. As simple as pressing another button, this trick is about as easy as it gets. Just grab your hairdryer and you'll be on your way to the volume you've always longed for.


How to use hot and cold air for volume

So what is this latest viral tip that has everyone buzzing for more volume?

According to the original TikTok video created by the hairstylist and founder of Act and Acre @helenreavey, the hack involves using your brush to hold up a small part of your hair from the roots, and then using your hairdryer to apply heat for 5 to 8 seconds in a targeted fashion near the base of your scalp. Immediately after, blast the same section with cold air for 3 to 5 seconds. Once you've applied the cold air, release the section and brush it out. After these quick and easy steps, your roots should stay up with lots more volume.


This entire process is meant to take four steps to complete and can be finished in just a matter of seconds. Even though it's meant to help those with fine hair, this trick can help almost any hair type. TikTok commenters have noted that it seems too good and simple to be true, so is there any science to back up this TikTok claim?

Does this TikTok hack work?

Even though it may seem too simple and easy, this volumizing hair hack is verified to be true.

According to the haircare experts at Sam Villa, using cold air after hot air is the perfect way to create a volumized look. Because hot air is the best way to change up the style of your hair, adding cold air immediately after lets the hair seal into place.


Hairstylist Ashley Rubell explains to Well + Good that cold air "not only seals the cuticle of the hair shaft but can give a smooth, shiny finish, especially when used with the appropriate brush."

Ultimately, cold air is an under-utilized tool on hair dryers that can help to serve so many purposes. Besides helping to lock volume into place, cold air can be healthier for the hair instead of only using hot air, per Nerd About Town. However, if what you're looking for is to add volume, be sure to mix in the two temperatures for that hairstyle you've always wanted.
