Salt spray is the texturiser of choice for most straight or wavy-haired ladies, but it turns out there could be something even more effective out there.
Actress and model Suki Waterhouse raised a few eyebrows earlier this year when she said she had moved on from washing her hair in beer, and had started using Coca-Cola instead.
"I don't like my hair when it's washed – it's fine and limp – but Coca-Cola makes it tousled, like I've gone through the Amazon or something," she told Us Weekly.
Much as we liked the sound of Amazon-esque hair for the price of a bottle of soft drink, we were a bit apprehensive to try out the suggestion ourselves. All that syrupy sugar… it could have been a recipe for disaster.
Luckily, one US beauty blogger has taken the risk for us.
How does it work? You saturate your hair in Coca-Cola over a bath or bowl, then rinse it out with water before air-drying or blow-drying.
According to Ellie, this trick works best if your hair is naturally fine, but even with her relatively thick hair she still saw a good result.
"My hair has some waves that it didn't have before," she says. "I like textured, wild bed-head looks, so I think this is pretty cool… and it's cheap."
