Let's take a moment for Sienna Miller's hair. Whether you're a bronde, blonde or brunette, looking for pixie-crop inspiration or fringe ideas, or you're simply on the hunt for hair inspiration pictures ahead of your next salon appointment, it's likely that Sienna Miller has popped up once or twice during your search for ideas. There's always been a lot of hype around Miller's trademark style - relaxed and bohemian, she long ago perfected the art of the carefree tousle. That's not to say that she doesn't mix it up with the odd polished look or two.
Take her look at last year's Venice International Film Festival. Miller attended the closing ceremony wearing a sheer Chloé dress and waist-length hair. Miller's iconic boho waves were back in business, loosely curled and kicking out in all the right places. The stylist behind her 2024 look? Luke Hersheson, who counts the likes of Victoria Beckham among his regular clientele.
How To Get Sienna Miller's Iconic Boho Waves At Home
So, how did Hersheson revive Miller's famous waves for the film festival? Here he breaks down the routine into a series of styling steps and products:
-
‘To add length, I used some tape extensions, putting two rows in the back, and one row in the sides. When they were in, I used a razor to cut the edges so that they tapered into nice little tendrils at the ends.’
-
‘I worked some of our Hershesons Zhoosh Foam, £16, through the hair to give it hold, then blow dried it in.’
-
‘After that, I used the large barrel wand attachment on the Hershesons Multi-Tasker, £195, which is a nice, big, chunky tong that forms a really soft bend in the hair. Instead of tighter “Spaniel” waves, you get a softer, more relaxed finish that looks really natural.’
-
‘To finish, I used some Hershesons Almost Everything Cream, £14, through the mid-lengths and ends, and separated the tonged pieces so the look felt quite ethereal and lived-in. When the wind hit her hair, it moved nicely.’
Sienna Miller's Famous Blonde Hair Colour Decoded
Colour wise, Miller had always erred on the golden side of the blonde spectrum, until October last year when she dabbled with creamy Scandi tones. Miller's new 'boho blonde' was the handiwork of Harriet Muldoon at Larry King.
'Sienna is embracing bright creamy Scandi tones this season,' says Muldoon, a renowned blonde expert, known for rustling up a similar look for Kate Hudson. 'I created contrast at the base by working with Sienna's natural colour and scattering the highlights, allowing room for depth. Adding in a Scandi hair line and backwash balayage set off the face frame to a tee and then there's softness through the crown. My new technique is skinny lights; fine, wispy highlights.'
Muldoon and Miller took inspiration from the late 2000’s when Miller was at the height of her boho girl fame and soft blonde looks reigned supreme.
If you're looking to recreate the look Muldoon advises asking your stylist for 'skinny lights with a fine weave that gives a softer finish,' that way the re-growth is easier to maintain, too. You'll also want to make sure the hairline stands out, 'it's the best way to contour the blonde,' adds Muldoon.
Sienna Miller's Go-To Hair Products
As for products, we have the inside track. One of Miller's all-time favourites comes from the famous Hair by Sam McKnight haircare line, the brainchild of the legend celebrity hairdresser himself. Taking to Instagram, the stylist (who is famed for his work with Princess Diana the entire cohort of 90s supermodels) shared a video of himself prepping the star's hair with a hefty dose of his iconic Cool Girl Texture Mist. Those who love an effortless, undone wave will likely already be familiar with the stuff. It's well known for its ability to give volume, grit, and touchable movement to hair with minimal effort - you just spritz, scrunch, and go. To maintain healthy blonde hair, Muldoon recommends Larry King Haircare's Good Life Shampoo, £18, for moisture and the City Life Shampoo, £18, for keeping your blonde bright.
