Not everyone can afford the $699 hair tool and if you can, it’s sold out everywhere. Cue this viral curling hack. The internet is losing it over this DIY trick for two reasons: it’s quicker than using a wand or straightener and it costs next to nothing. Now everyone can curl their hair with air. All you need is a hairdryer and a recycled plastic bottle.
The technique was first spotted on Facebook and quickly emulated by a host of beauty bloggers. Most recently Huda Katan (@huadbeauty) shared the hack with her 28.7 million followers.
Here's how to curl your hair with a hairdryer and a recycled water bottle:
1. Cut the top off a recycled plastic bottle and create a rectangular incision that's about the same size as the nozzle on your hairdryer.
2. Place a section of your hair (about 5cm in diameter) inside the bottle
3. Place the hairdryer's nozzle inside the incision and blast hair for about 8 seconds.
4. Huda warns that the bottle can get quite hot so wearing gloves is recommended.
