The Princess of Wales debuted a striking new look this week—but not everyone was kind about it.

On Thursday, September 4, Kate Middleton appeared at the Natural History Museum in London alongside Prince William, revealing a fresh blonde hairstyle that UK media quickly dubbed “regal blondette.” It marked a bold departure from her trademark brunette locks and was the couple’s first joint public outing in nearly two months.

But while many praised the princess’s lighter hair, online trolls flooded social media with cruel speculation. Some accused Kate of wearing a wig, mocking her for what they described as “unnatural volume” and extensions. Others even went as far as to compare her new style to “Party City wigs.”

The harsh comments struck a nerve with Sam McKnight—Princess Diana’s legendary former hairstylist—who rushed to Kate’s defense.

“I am shocked, horrified, dismayed, and disgusted by all the nasty comments about the Princess of Wales today,” McKnight wrote in a passionate Instagram post. “A woman’s hair is very personal to her, it’s armor, defense, confidence, and so much more.”

He condemned the cruelty, noting how many of the comments seemed to come from women attacking another woman who, by her position, “has no choice but to bravely face the public.” McKnight added that he was “sure” Kate would often prefer a life away from scrutiny, but instead continues to represent the UK “brilliantly, quietly, and unselfishly.”

His message ended on a sharp rebuke of the trolls: “Cancer affects individuals differently, but is life-changing for everyone. So FFS LEAVE HER ALONE. SHAME ON YOU.”

The moment was particularly poignant as Kate, 43, revealed last year that she was in remission after undergoing treatment for cancer. Psychologist Carolyn Mair told Fox News that the princess’s hair transformation could symbolize a powerful emotional shift.

“Hair is our crowning glory and a symbol of health and femininity,” Mair explained. “Kate might want to make a fresh start by embracing a lighter outlook on life. She may be reclaiming agency and visibility, and leaving her illness behind.”

Outside the museum, the Princess of Wales showed her characteristic grace when a well-wisher complimented her new look. Blushing, she smiled and replied: “How embarrassing, you’ll make me blush.”

Despite the online negativity, Kate’s blonde transformation appears to be much more than just a hairstyle—it is a statement of resilience, renewal, and quiet strength in the face of constant public scrutiny.
