The exact hair styling products behind Sienna Miller's beachy waves
Ever wondered how Sienna Miller achieves her effortlessly chic beachy waves? Thankfully, Luke Hersheson, expert hairstylist, CEO of Hershesons and hairstylist behind Sienna's notable wavy hairstyle, revealed the exact buys behind the actress' standout look.

Why buy one tool when you can get a 3-in-1? You might have seen our Hershesons Great Hairdryer review, but the Multi-Tasker is the all-new tool on the block from the brand. Whether you're looking to create salon-worthy tousled waves, a bouncy blow dry or Hollywood curls, this tool allows for them all with its interchangeable styling heads.

The clue is in the name of this haircare must-have: the Almost Everything Cream does exactly what it says on the tin. Whether you're looking to condition your strands, tame frizz and flyaways, define curls, add texture or use as a nourishing mask, this gem does it all (plus much more) - and boasts a salon-worthy scent, too.
Dubbed 'Boho Waves', Sienna debuted the low-maintenance hairstyle last summer during the Venice Film Festival and Chloe’s Spring/Summer 2025 show. The hairstyle in question captures subtle, undone waves and face-framing tendrils that give a natural, slept-in appearance for an effortlessly put-together look.
To give the actress' strands some body and bounce before styling, Hersheson reveals: “I worked some of our Zhoosh Foam through the hair to give it hold, then blow-dried it in.” Although the hairstylist relied on tape extensions to add length to Miller's locks, this look can be easily recreated on an array of different hair lengths.
As for the tool used to create the beachy waves, the hairstylist was equipped with his brand's latest launch, the Hersheson Multi-Tasker: “I used the large barrel wand attachment on the Multi-Tasker, which is a nice, big, chunky tong that forms a really soft bend in the hair," he says. This attachment ensured the effortlessness that we all admire Sienna Miller for, Hersheson adds: "Instead of tighter “spaniel” waves, you get a softer, more relaxed finish that looks really natural.”
To complete the look and allow for some natural movement, Hersheson "used some Almost Everything Cream through the mid-lengths and ends, and separated the tonged pieces so the look felt quite ethereal and lived-in." But, Sienna Miller isn't the only A-lister who's a fan of this versatile styling cream; in fact, it's also Keira Knightley's hair cream of choice, too.
