The 'jellyfish haircut' is the celebrity-loved hair trend you've seen everywhere – 14 ways to style the modern look
The jellyfish haircut first gained popularity in Japan and South Korea but has since made its global debut – and as an experimental hair girlie (read: commitment-phobe), I couldn't be happier. But with such an ambiguous name, what actually is the jellyfish haircut? Who is it best suited to? And of course, how is it best styled?
Well, to get the lowdown on all things jellyfish, we spoke to professional hairstylist Chlöe Swift, who shared her expertise on everything we need to know about the rising trend. Let's just hope it doesn't sting, hey...
The jellyfish haircut is not for the faint-hearted, merging two polarising haircuts together, making for an avant-garde look. "There are two distinct layers; a short, blunt bob shape cut to around chin level, followed by long, flowing layered hair underneath," Chlöe explains, "and together, this resembles the shape of a jellyfish."
The style, however, can be modified with graduating layers to soften the striking contrast of lengths. (See the inspiration pictures below for varying iterations of the cut.)
You may have spotted its rising popularity over the last couple of years, with celebrities including Billie Eilish, Miley Cyrus and Gwen Stefani all jumping onto the trend. And while it's not all that new, trends do take a few years to filter down into the mainstream, meaning it's only going to continue to grow! In fact, Chlöe predicts we'll still be seeing the jellyfish and iterations of this cut in 2026. Watch this space...
"It's definitely a fun haircut trend for those who like to stand out, make bold and creative style statements and are happy to experiment with their hair," Chlöe notes. So, who dares to rock the jellyfish?
"Naturally, straight hair works so well for a sleek and sharp look to your jellyfish cut," Chlöe says. This is because the layers are more defined with this hair type. "But equally," Chlöe adds, "naturally wavy or curly hair (from 2b – 3b) can also work for a softer, more natural feel."
In terms of hair texture, Chlöe says that thick hair is best suited to the jellyfish cut. "If you have very thick hair, this cut is a good style option for you as the shorter layers reduce a lot of bulk in the hair."
More generally, layered hair requires a little TLC when it comes to styling, and the jellyfish cut is no exception. "For a sleek and structured look, blow dry the hair smooth with a round brush and hair dryer, but aim not to bend the ends under too much with the round brush," advises Chlöe.
"I'd recommend applying products to damp hair. This will give you that sleek, glass hair shine." Both a fave of Chlöe's and team Cosmo Beauty is the Redken Acidic Bonding Concentrate Leave In Treatment; it leaves the hair ultra smooth and glossy, as well as protecting strands from heat damage.
That said, if you're aiming for a more wearable style, we've got good news; Chlöe shares that the jellyfish cut can also be styled naturally if you're working with wavy or curly hair. In this case, a texturising spray or mousse will be your BFF to give a more casual, lived-in vibe.

The 'jellyfish haircut' is the celebrity-loved hair trend you've seen everywhere – 14 ways to style the modern look
Following the mixie (aka, the mullet x pixie hybrid), I didn't think the mainstream could get any bolder with their haircuts, that was until the jellyfish haircut swam onto the scene... Soz.

There's a shade of blonde that'll suit everyone! 9 bombshell hair colours from toasted beige to icy white
Blonde may seem like just one blanket colour, but step into any salon and you'll quickly realise it's a full spectrum of sun-kissed brilliance. Whether you're craving a soft, low-maintenance glow or an ultra-glam transformation, there's a blonde out there with your name on it – from toasted beige tones to bubbly champagne hues. You could say they're good enough to eat... and drink... Jokes aside, the biggest misconception about going blonde is that it's best suited to those born with it (read: "I was blonde as a baby!!"). However, all thanks to modern colouring techniques (and a very skilled stylist), everyone can find their perfect blonde moment. Side note: Here at Cosmo Beauty, we always recommend having your hair coloured by a professional, especially if you're going blonde! After all, bleach is not your fragile strands' best friend. Not sure where to start? Well, with the expertise of celebrity hair colourist Marley Xavier, we've decoded the top nine shades of blonde that you should have on your radar right now. So, whether you're a brunette going bold or a natural blonde looking to level up, consider this your guide to finding your inner (and outer) bombshell. As its namesake would suggest, butter blonde is a warm, creamy yellow-toned blonde that mimics the richness of softened butter. Think: Delicately warm and effortlessly polished. "Butter Blonde brings a sheer golden glow to the hair," Marley says. "It works especially well on sun-kissed or warmer skin tones and adds an understated richness that feels both timeless and elevated." Champagne blonde blends soft golden and cool beige tones, creating a sparkling, neutral hue – just like a bottle of your favourite bubbly. "Elegant and softly luminous," Marley describes. Continuing, Marley says that this shade of blonde is best suited to neutral and fair complexions. "With hints of beige woven through, it suits neutral and fair complexions beautifully, adding a soft radiance without tipping into icy territory." If you're looking to add more depth and warmth to your blonde (without looking brassy), listen up... Rich and honey-like, this blonde shade has a golden hue with amber undertones, which Marley says is best suited to medium to deep skin tones. "It works especially well for those with amber, brown or hazel eye colours", he adds. "It's a sophisticated way to lighten the hair without losing warmth or dimension, and can also work well on those with lighter complexions looking to add a natural-looking golden glow." It may sound ambiguous and intriguing, but linen blonde is a shade not to be feared. As shown with the reference picture below, linen blonde is a soft, muted, creamy beige with cool undertones, resembling natural, sun-faded hair. "This shade is best suited to fair to light-medium skin with cool or neutral undertones," Marley says, adding that "it's polished and luminous without ever feeling stark." Scandi blonde is an ultra-light, platinum-toned blonde – and yep, you guessed it: It's popular among the Nordic Scandi gals. "It flatters very fair, cool-toned skin," Marley says. "Golden Hour Blonde captures that late-day sunlight with liquid gold tones and a beachy softness," Marley shares. It's warm and rich with hints of caramel tones. "It flatters olive and deeper complexions," he adds, thanks to the natural, radiant, glowing undertones in the skin. Effortless blonde is a soft blonde that embraces a natural root and blends beige, honey, and sun-kissed highlights for a lived-in finish. "Think texture with a subtle balayage feel that grows out beautifully — often brighter around the face for that sunlit lift," says Marley. And good news! This shade suits nearly everyone, Marley tells us; "It feels as relaxed as it looks, combining low maintenance with polished finesse." Icy blonde is an almost silver-toned blonde with super cool undertones, creating a striking, edgy look. Marley recommends this shade for those with fair to light-medium skin tones, especially those with cool or neutral undertones. "It looks amazing with blue eyes and delivers ultra-modern, high-gleam impact, the blonde for strong personalities," he says. However, due to its striking, unnatural tone, it can be worn by anyone willing to make a statement! Give it a go, should you dare... If you put beige in a toaster, you'd get this ~almost~ burnt creamy shade... Duh! But in all seriousness, the colour combines neutral beige with slightly warm undertones, giving it an earthy yet luxurious feel. "It flatters neutral and warm complexions with ease," Marley adds. Marley Xavier is a celebrity hair colourist and resident artist at Hershesons salon, best known for his work with clients including Paul Mescal, Courtney Love and Victoria Beckham. With years of experience behind the chair, Marley brings sharp, editorially-minded insight on colour trends, timeless styles and industry tips and tricks.

9 Shaggy Bob Haircut Ideas and Styling Tips
Thinking of breaking up with your long layers? (And your bf... but that's a story for a different day...) Enter: The shaggy bob, a retro-meets-modern haircut that's effortlessly cool and full of attitude. But the questions on everyone's lips? What exactly makes a bob shaggy? How is the 'do best styled? And how can you revamp the 1970s cut into a fresh 2025 take? Well, with the expertise of professional hairstylist Chlöe Swift, your dream hairstyle and all there is to achieving it is just a scroll away. Snip snip! As its namesake would suggest, a shaggy bob is the combination of two iconic styles: the classic bob and the '70s shag. "It's got the blunt shape of a bob but with all the choppy, textured layers that give it that cool, undone edge," hairstylist Chlöe Swift says. "The shag part of the look is all about layers, movement, and texture," says Chlöe. "It usually features shorter layers around the crown, often paired with a fringe, working really well with natural wavy textures." So, paired with the shorter lengths of a bob makes for a shaggy bob. Stevie Nicks and Jane Fonda of the 70s, and even Meg Ryan circa 2000, we're coming for your rock and roll hair. Good news! According to Chlöe, the shaggy bob is super adaptable. "It suits most face shapes – you may just need to tweak the length of the layers and overall length. For example, round faces would need longer face-framing layers and a longer overall length (past the jawline) to help elongate the face. "Whereas heart-shaped faces could opt for a heavier fringe as they have more space on the forehead, and could go for a shorter overall length to highlight a smaller jawline." Hair type-wise, the shaggy bob is great for those with medium to thicker hair types, particularly if you have natural texture or curls. Chlöe says that "the layers of the cut enhance that natural texture and take away some weight." That said, fine hair types can wear it too, "especially if it's more volume and shape you're looking for," Chlöe says. But just remember to keep the ends blunt for a fuller look. The shaggy bob is a style that's meant to look lived in. Think: 'I woke up like this', meaning that on a day-to-day basis, it's relatively low-maintenance. That is "if you're happy with that tousled, imperfect finish," Chlöe emphasises. "Regular trims are key to keep the layers fresh and avoid the shape going flat," Chlöe counters, adding that a salon appointment every six to ten weeks may be necessary, depending on your preferred length. As mentioned, the styling of a shaggy bob depends on your hair's natural texture—the wavier, the better. But Chlöe says that her go-to advice is: enhance what you've already got. "If you've got waves or curls, use a diffuser with a bit of mousse or curl cream to bring them out. I love to use Oribe Matte Waves Texture Lotion before diffusing my hair."If your hair is more on the straighter side, then a sea salt spray (like Maria Nila Salty Mist) or a dry texturising spray (like Living Proof's dry volume & texturising spray) can give your hair that gritty, undone texture it needs."
