Social media is bursting with hair and beauty hacks that enthusiasts swear by and one that is currently doing the rounds claims to boost the volume of your hair do in just 15 seconds.
Those who long for more voluminous locks have taken to TikTok, as searches on how to add more volume to roots have reached over 3.1M on the app.
In a video shared by account Hotli Beauty, the "trick that all girls must know" simply involves using a brush, some hot air, and some cold hair on already dry roots. The viral clip has already garnered over 10.6m views and nearly half a million likes, the Express repots.
First, take your hairbrush and place it about two inches from your parting. Next, push the brush in an upwards movement towards the centre of your head to create some lift.
Next, using a hair dryer, blast the hair with hot air for five to eight seconds. Finally blow the same section with cold air for three to five seconds.
Viewers with straight hair were eager to give the tip a try as it works best on flatter manes that need an extra push. "Might have to try this for my volumeless hair," another said, while another commented, "I’m gonna try this!"
Other TikTok users vouched for the hack, and one said: "I've been doing that for decades."
Why does this hack work so well? It's all about hair chemistry and the application of heat. Hot air is ideal for styling the hair, essentially shaping it into the look you desire. Cold air is ideal for locking that style in place.
This is because hot air makes hair more malleable by loosening the bonds in the strands. The cool air then locks these bonds in place.
This hack works so well because of the application of hot and then cold air. Most hair dryers now have hot and cold settings, but if yours doesn't, using just the hot air and holding the brush in place until the hair cools could help.
