There's a hack for perf curls using a plastic bottle and hair dryer and we're so in

trending

So we're all about the 'hardcore' hair products but those things can set ya back a fair few hundred dollars which we're not always stoked about. Enter Instagrammer Olivia Smalley from Florida.

Olivia uses a plastic bottle with the top cut off and a slit cut in the side. She gathers her hair inside the bottle and then puts her hairdryer in the slit in the bottle before turning it on. The hairdryer causes the hair to spin round inside the bottle. When she removes the hair and runs her fingers through it, she has the waves of our dreams in her hair!

It's a bit DIY but omg it's worth a try!!
