Hair we go! ‘The Kate Effect’ sweeps salons as Princess’s ‘Posh Mum Bronde’ becomes most in-demand hair colour, royal stylist reveals

There’s a new hair colour quietly dominating salons this season, and it comes with a very royal seal of approval.

Dubbed the ‘Posh Mum Bronde’, the chic, in-between shade has officially entered the spotlight thanks to the ‘Kate Effect’ after the Princess of Wales unveiled her most luminous hair colour yet.

Effortless, grown-up and undeniably expensive-looking, the ‘Posh Mum Bronde’ blends brown and blonde tones to create a polished finish that never feels try-hard.

Her colour is neither overtly blonde nor traditionally brunette, striking that elusive sweet spot that feels modern, sophisticated and incredibly wearable.

Already favoured by style icons including Victoria Beckham and Jennifer Aniston, the shade is becoming a go-to for women seeking understated glamour – and now, thanks to Catherine, it’s firmly been cemented as the hair trend of the season.

Kate’s latest appearance at Charing Cross Hospital offered a masterclass in the look. Her hair appeared glossy, healthy and softly honey-toned as the refined bronde shimmered beautifully in the winter light.

The updated shade was on show on Christmas Day at Sandringham, where, beneath her hat, her long waves appeared noticeably brighter and more voluminous than ever before.

Was this the beginning of a new royal hair era? According to hairdresser Jo Hansford, the answer is yes.

‘The depth and richness of her new shade beautifully enhance her skin tone and eye colour, creating a look that feels both modern and timeless,’ Ms Hansford told the Daily Mail. 

‘Polished and understated, her hair radiates sophistication and elegance, which are hallmarks of Catherine’s signature style,’ said Ms Hansford, who was awarded the prestigious Royal Warrant of Appointment from Her Majesty The Queen. 

What sets the ‘Posh Mum Bronde’ apart, and why it’s proving so popular, is its low-maintenance appeal. Unlike high-contrast blondes or flat brunettes, this blended shade grows out seamlessly, with no harsh lines at the roots.

It’s flattering, forgiving and ideal for women who want their hair to look impeccable without constant upkeep.

‘Richer tones with added depth play a crucial role in creating balance and harmony with certain skin tones,’ she added. ‘Without these blended shades, going too light can leave the complexion looking overly pink or washed out.’

The subtle depth at the roots kept the look grounded and regal, while lighter, honeyed lengths introduced a sense of softness and modern ease. 

It’s aspirational, yet entirely attainable, which is precisely why ‘the Kate Effect’ is already taking hold.

For brunettes looking to replicate the look, the key lies in restraint. 

Rather than bold contrast, ask your colourist for extensive highlights that are lifted first and then toned right down. 

According to Ms Hansford, this prevents brassiness or orangey fade, particularly on hair prone to warming, and ensures a neutral bronde finish with delicate dimension.

The look has officially been crowned colour of the season 

For years, the Princess of Wales’ brunette has held an almost mythic status. 

Rich and elegant, it has evolved subtly with the seasons, deeper and cooler through winter, warmer and sun-kissed as spring and summer approach. It never looks flat or heavy, thanks to fine ribbons of lighter colour that add movement and lift.

Her latest iteration is perhaps the most refined yet. 

Infused with honey and caramel tones, the bronde shade frames her face beautifully and enhances her natural colouring. 

Crucially, the colour never overshadows Kate herself. 

It works in harmony with her make-up, wardrobe and calm, assured presence. Nothing about it feels forced. She hasn’t abandoned her signature look, she’s simply elevated it. 

‘While many clients choose lighter colours for practical reasons, such as easier maintenance, softer regrowth or grey blending, this look is a reminder that depth and dimension often deliver the most flattering, refined results,’ explained Ms Hansford.

And with that, the ‘Posh Mum Bronde’ has officially been crowned the most elegant hair colour of the season.
