I consider myself someone who is pretty low-maintenance with their hair. I don’t like spending ages with a hair tool when styling my lengths, and so I’m always drawn to low-effort hairstyles that not only look effortless, but are also effortless to create, too. And if you’re like me and the rest of the internet, you too have been swooning over Zendaya’s The Odyssey press tour hair moments, which have been featuring some stunning Grecian-inspired waves that I’ve been desperate to recreate. And as we’re in the height of summer, now is the perfect time to try S-waves. I spoke with a top hairstylist to break down exactly how to achieve this low-effort style for summer.

How to Do S-Waves

“S-waves are a looser, more luxe take on the classic mermaid waves and the perfect style for summer,” says hairstylist and ghd ambassador Patrick Wilson. “It tells the story of an ‘I just got out of the sea’ glossy look that looks effortless and summery. The style is all about having luxuriously deep waves with a shaken-out finish for an uber fresh, cool look,” he says. “It is all about creating a subtle, wavy texture rather than curl. This is a flatter wave that doesn’t have the volume or width of a traditional curly blow-dry, making it ideal for a more modern, sleek look. It’s a great look that can be created on all hair lengths.”

What You’ll Need

To create your S-waves, you’ll need a good heat protector, a pair of hair straighteners, a wide-toothed comb and a texturising spray or salt spray.
