And while celebrities like Olivia Palermo and Jessica Alba have always been great points of call for inspiration, even Kate Middleton seems to be a fan of the style in 2020, with some of her video correspondence showing her usually bouncy blow dry traded in for more subdued waves.
Beside the fact that it's always on-trend for summer, the comeback has also been fuelled by people at home learning how to braid, trying sleep and wear styles (like plaiting the hair before bed or tying the section in rags), rather than reaching for hair tools throughout various months of quarantine and lockdown.
It's a great way to give your hair a break from heat, with a brush out style ready-made in the morning. Although, if it's a hair tonging step-by-step your after, Bec Judd's beach wave how-to is one for the files.
That said, even with the royal seal of approval, this beach waves don't have to require a lot of effort—or, for that matter, a beach.
Below, our favourite products for nailing the look sans any time in the sea.
Lady Jane Salon Pro Beach Waves Styling Brush, $29.99 at Lady Jayne
The first-ever hairbrush dedicated to creating beach waves, this styling tool is excellent for producing that tousled, tumbling look without even stepping on the sand. Ideal for medium to long hair, its heat activated ceramic copper barrel allows for even distribution of heat while you're blow-drying your hair. To nail the look, change the angle of the brush as you blow dry to create different textures in your hair for the perfect beach wave look.
Wella Professionals EIMI Ocean Spritz, $24.95 at Oz Hair & Beauty
If you prefer to go without heat styling entirely, this sea salt spray has got you covered. Great for creating that undone beach texture, it also helps protect hair against dehydration and UV damage. Simply spray onto dry or slightly damp hair and then scrunch or shape with your fingers. For an even chunkier texture, you can below dry after shaping.
Mermade Hair Pro Waver 32mm, $89 at Adore Beauty
Not opposed to a little heat? This pretty pink tool is going to be your go-to for quick, one-stop mermaid hair. With three ceramic-tourmaline barrels and an easy-to-use clamp, the Mermade hair wand is specially designed to create big, bouncy waves with minimal effort. It comes with a matching black heat-protectant glove (safety first) and has a swivelling cord so you don’t get too tangled up.
