These Y2K Hair Colours Are Making a Comeback—How To Wear Them in 2026, According to Experts
From pastels to ribbon highlights, these nostalgic hair colour trends are everywhere again.
As someone old enough to have dipped my toe into Y2K beauty trends the first time around, I've got a soft spot for the pastel streaks, chunky highlights and dip-dyed ends that defined the era. After watching '90s fashion, noughties beauty and even our favourite TV shows make a comeback, it was only a matter of time before the hair colour trends followed. From ribbon highlights to candy-coloured pastels, the nostalgic looks I once begged my hairdresser for are back—and this time, they're chicer than ever.
Colourist Harriet Muldoon at Larry King South Kensington agrees. "At the beginning of the year we [witnessed a big] 2016 throwback, and I think it began to tease us with the nostalgia of pastel hair," she tells me.
Alongside flip phones and frosted lip gloss, the Y2K era was all about exaggeration and making iconic moves. "For colour, this was a really major period. The use of vivid colours and unique section patterns made it so exciting to be a colourist," adds Muldoon. Recalling the signature shades, she says, 'For technique, we were looking at chunky highlights, strong section patterns and the beginning of the dip dye, and it ranged from vivid colours to pastels."
Thinking of giving it a go? Muldoon agrees. "It's a great time of year to go for these shades as they really stand out in the summer. If you're unsure about what's right for you, speak to your colourist, get a moodboard together and have some fun. You can always go for just the tips if you just want to dip into it," she adds.
Below, we spoke to stylists and ambassadors for L’Oreal Professionnel and Colour Trophy, Adam Read and George Curran, on how the trends have come back around and how to wear them for 2026.
1. Pastel Pink
As Muldoon tells me, pastels were a huge Y2K trend, and bringing the colour palette back only weeks ago was none other than Kylie Jenner. Famed for her bold hair colour choices, we love this soft pastel take on long locks, proving the nostalgic trend is making a stylish comeback for a new generation.

2. Velvet Brunette
Rich, glossy brunette was a defining look of the Y2K era, worn by stars like Anne Hathaway, Katie Holmes and Eva Longoria, whose deep chocolate shades became synonymous with glossy, healthy hair.
Today's take moves away from flat, single-process colour in favour of a more nuanced finish. "Brunette is becoming richer and more dimensional. Rather than flat, solid colour, we’re seeing luxurious depth with multiple tonal reflections," reveals Reed.
It's a trend, Reed believes, that is "best suited to natural brunettes wanting richness without dramatically changing their colour, or blondes looking to return to darker hair in a softer, more sophisticated way." He adds that this isn't about dialling down the colour. "The most luxurious brunette isn’t the darkest; it’s the one with the most dimension. When light moves through the colour, the hair comes alive."

3. Lived-In Grey
Sonic silver blonde hair was a big late '90s, early '00s trend, but as Reed puts it, "We’re seeing a real shift in the way people think about grey hair. Rather than feeling the need to cover every silver strand, clients are embracing their natural colour and asking how they can make it look intentional, healthy and beautifully lived in."
This isn’t about letting grey simply grow out. It’s about working with it. "Through thoughtful colour placement, glossing and soft blending, natural silver becomes part of the overall colour story, adding depth, light and dimension," adds Reed.

4. Cowboy Copper
The copper of Y2K yore has evolved from a bold fashion statement into something much more wearable. Instead of bright orange reds, velvet copper combines cinnamon, chestnut and soft auburn tones to create richness and sophistication. "Clients still love warmth, but they want elegance over intensity. Cowboy copper feels luxurious because it's soft, multi-dimensional and catches the light beautifully," reveals Curran.
It's best suited to fair through medium skin tones wanting warmth without dramatic commitment. "Think Sadie Sink, Emma Stone and Kelly Reilly," he adds.

As well as rich colour, this dye blends avocado, olive, shea, cranberry, and argan oils to leave hair an incredible three times shinier and significantly stronger.
5. Gold Rush
Golden blonde ruled the early 2000s, with glossy, sun-kissed shades becoming the signature look of stars like Sarah Jessica Parker, Cat Deeley and Sienna Miller. But unlike the brassy, high-maintenance blondes of the era, today's revival is softer and richer. "This isn’t the gold of the early 2000s. Think refined honey, soft caramel, buttercream blondes and beautifully balanced golden ribbons that reflect light naturally," reveals Curran.
As for who it's best suited to? "Anyone wanting to add warmth and brightness to their complexion. It’s particularly flattering on mature skin as it restores softness and luminosity," he says.

6. Skin Tone Hair

Think back to the glossy, expensive-looking hair colours that defined the early 2000s. Jennifer Aniston's honey blonde, Jessica Alba's caramel brunette and Eva Longoria's glossy chocolate brown all had one thing in common: they were chosen to enhance each woman's natural colouring rather than overpower it. Whilst today's version is far more bespoke, the inspiration remains the same. "The perfect hair colour is one that doesn’t feel like it’s been done. It simply looks like the best version of you," says Reed.
As for what makes it modern this time around? "Colour is selected to complement skin tone, undertone, eye colour, natural hair colour and even wardrobe palette, making every result completely bespoke," adds Reed.
The good news is that everyone can get in on this trend. "The beauty of 'skin tone hair' is that it isn’t one colour; it’s an approach. By taking into account the individual rather than following trends, the result always feels authentic," adds Reed.

7. Heritage Blonde
Heritage blonde is inspired by iconic techniques from previous decades but blended seamlessly with modern colour placement, softer root transitions and luminous glossing. "It's best suited to existing blonde clients looking for an update rather than a complete transformation," reveals Curran. Think Gigi Hadid, Margot Robbie and Sienna Miller.

8. High-Contrast Highlights
High-contrast highlights are making a major comeback, reviving the bold, statement colour that defined the Y2K era. Instead of ultra-blended balayage, the focus is shifting back to brighter, more defined ribbons of blonde that create instant dimension and frame the face. The trend has recently been spotted on Megan Thee Stallion during her Fiji getaway, proving that bold, high-impact colour is firmly back on the agenda.
