The Hair Looks to Watch This Autumn at Fashion Week

September 15, 2026 Annie Clark

Fashion Week is one of the best places to spot what’s coming next. While the clothes might be showcasing the season ahead, the beauty looks created backstage often have a way of making their way into our everyday routines long before the collections reach stores.

This September, the fashion world turns its attention to the Spring/Summer 2027 collections, with New York, London, Milan and Paris taking centre stage throughout the month. Copenhagen has already given us the first glimpse at the SS27 beauty direction, and one thing is becoming clear: hair is moving towards a more individual, effortless and expressive approach.

From long, flowing lengths and natural movement to undone ponytails, statement volume and nostalgic styling, the hair looks emerging around Fashion Week are giving us plenty of inspiration for the season ahead.

And if the current return to longer hair is anything to go by, hair extensions are set to play a major part in creating some of the most covetable looks.

Long Hair Is Having a Major Comeback

One of the biggest hair stories of 2026 has been the return of long hair.

After several seasons where bobs, lobs and shorter cuts dominated the trend cycle, Harper’s Bazaar recently highlighted the resurgence of long hair, with celebrities and beauty insiders embracing longer, looser styles once again.

The new approach to long hair feels very different from the ultra-polished lengths of previous years. Instead, it’s about movement, softness and creating hair that feels effortless.

That makes it particularly exciting to watch as the SS27 Fashion Week season unfolds.

Long hair gives salon professionals so much more to work with. It can be worn loose and flowing, pulled into a ponytail, styled into a romantic updo or given texture through waves and curls. It can also completely change the proportions of a look, which is exactly why longer lengths remain such a favourite backstage.

For anyone who doesn’t have the length they want, hair extensions offer an easy way to embrace the trend. SWAY Seamless Clip-Ins can instantly add length and volume, giving you the freedom to experiment with longer hair without having to step foot into a salon.

Undone Hair Is Becoming the New Polished

If there’s one theme already emerging from SS27, it’s that hair doesn’t need to look overly styled to look considered.

At Copenhagen Fashion Week, which took place in August, beauty looks leaned towards natural texture and deliberately undone styling. Loose ponytails and buns featured flyaways and a less polished finish, while different hair lengths, textures and partings were allowed to exist side by side.

The beauty of undone hair is that it works with your natural texture rather than against it. Soft waves, relaxed lengths and loose pieces around the face can make a hairstyle feel modern without looking like you’ve spent hours creating it.

This approach also works beautifully with hair extensions. Added length can give natural movement more impact, while additional volume can create the fuller, more effortless silhouette that Fashion Week stylists are favouring. The finished result should feel like your hair, just with a little more of what you love.

The Return of the Ponytail

The ponytail is one of those hairstyles that never really disappears, but Fashion Week always finds a way to give it a fresh perspective.

This season, we're expecting to see plenty of low and mid-height ponytails, with the emphasis on length, movement and texture rather than overly tight styling. A sleek ponytail can create a minimalist, fashion-forward finish, while a softer version with loose strands and movement through the lengths feels much more relaxed.

And this is where hair extensions can really make a difference. A longer, fuller ponytail instantly has more impact. Added length allows the ponytail to cascade down the back, while additional volume through the ends creates a fuller silhouette.

It's proof that sometimes the simplest hairstyle can make the biggest statement.

Volume Is Making a Comeback

If the return of long hair is one of the biggest trends of the year, volume is its natural partner.

For a while, ultra-flat, sleek hair dominated the beauty landscape. Now we're seeing a shift towards fullness, bounce and movement.

Think big blow-dries, fuller ends and soft volume through the roots and lengths. Not necessarily huge, dramatic hair, just hair that feels healthy, abundant and full of life.

The beauty of hair extensions is that they can give you more to work with when creating these styles. Additional hair can add fullness through the lengths, making a blow-dry feel bouncier and curls look more substantial. This is particularly effective when paired with longer lengths, creating that effortlessly full look that feels straight from the runway.

The Return of 90s Inspired Hair

The influence of the 90s isn't going anywhere.

From supermodel-inspired blow-dries to sleek ponytails and voluminous lengths, some of the decade's most recognisable hair looks continue to influence what's happening in beauty today.

But rather than recreating the decade exactly, we're seeing a more modern interpretation.

Think soft volume rather than excessive styling. Glossy lengths rather than overly rigid finishes. A bouncy blow-dry that feels polished but still natural.

Longer hair is the perfect foundation for these looks, giving you the length and fullness needed to create those iconic silhouettes.

And with hair extensions, you can experiment with your look without committing to growing your hair for months first. Unsure what method or colour to choose from? Book a free colour match consultation.

Romantic Updos

For the evening shows, expect hair to become a little more dramatic.

Updos are always a Fashion Week favourite because they allow stylists to create something sculptural and unexpected, but this season the trend feels softer and more romantic. Loose buns, textured chignons and relaxed twists can all create an elegant finish without feeling overly formal.

Longer hair makes these styles much easier to create, particularly when you're looking for a fuller bun or a more substantial shape. Hair extensions can give you the extra length needed to create intricate styles, while additional volume can help the finished updo feel fuller and more dimensional.

It's a reminder that hair extensions aren't just about wearing your hair down. They can completely change what's possible when it comes to styling.

Texture Is Becoming Part of the Look

One of the most exciting shifts in hair is the growing appreciation for texture. Rather than trying to make every strand look identical, stylists are increasingly embracing natural movement, flyaways and individuality.

This doesn't mean hair has to look messy. It's about allowing some personality into the finished style.

A few loose pieces around the face, natural waves through the lengths or slightly undone ends can make even a polished hairstyle feel more modern.

For hair extensions, this is particularly important. The goal should always be a seamless blend that works with your natural hair, allowing you to style the whole look together rather than creating an obvious distinction between your own hair and your hair extensions.

Hair Colour Is Getting More Dimension

The return of longer hair is also giving colour more room to shine. Rather than relying on one flat shade, dimensional colour can create depth through the lengths and make longer styles feel even more dynamic.

Blended blondes, rich brunettes, warmer tones and subtle highlights can all add another layer to the overall look.

This is where choosing the right hair extension shade becomes important. A seamless colour match can make hair extensions look incredibly natural, while blended shades can introduce dimension and create a more personalised finish.

As the Spring/Summer 2027 collections take over Fashion Month, colour will be another detail worth watching, particularly when paired with the season's growing focus on long, healthy-looking hair.

The Hair Mood for SS27

As Fashion Month unfolds this September, we're expecting to see one thing above all else: individuality.

The best Fashion hair trends aren't necessarily the most dramatic ones. They're the looks that can be taken from the runway and adapted to suit your own style.

That's why long hair is such an exciting trend to watch. It can be glamorous or understated. Sleek or textured. Minimal or statement-making. The same applies to the ponytail, the bouncy blow-dry and the soft wave. Each can be adapted depending on how you want to feel.

Fashion Week gives us inspiration. What we do with it is entirely up to us and with hair extensions, you have even more freedom to experiment.
