Kate Middleton’s noticeably lighter blonde hair has sparked months of speculation, and now the Princess of Wales has offered a surprisingly simple explanation.

While attending the Royal Variety Performance in London, the 43-year-old royal addressed the topic directly after actress Su Pollard complimented her on the new shade—a look that has drawn even more attention as Kate gradually returns to public life following cancer treatment.

A Low-Key Reason Behind the New Look

Kate’s golden-toned hair has become a frequent topic online, but her explanation was far more casual than royal watchers expected. When Pollard told her, “I like your hair, it looks a lot lighter,” the princess responded with: “It used to be brown, but it’s gone light in the sunshine.”

The understated comment, first reported by the Daily Mail, immediately spread across social media. Many fans accepted the explanation, but some questioned whether the sun alone could have lifted Kate’s naturally dark hair so dramatically, with one online user saying, “Umm, love Princess Kate, but that didn’t come from the sun. And she’s also wearing extensions.”

Kate first appeared with noticeably lighter hair in September during a visit to the Natural History Museum gardens with Prince William. Observers noted the honey-toned shade running through her brunette hair. However, only two days later at the Women’s Rugby World Cup, she appeared with darker strands again, leaving royal watchers guessing what inspired the quick changes.

A Quiet Moment With Jessie J

The Royal Variety Performance also brought a surprisingly emotional exchange between Kate and singer Jessie J, who recently revealed her own cancer diagnosis. The musician later spoke to The Independent about the interaction, saying, “Mum to mum, who has just recently gone through cancer, I just wanted to give her a hug.” She added, “We acknowledged that it’s something that is not easy to go through, especially in the public eye.”

Jessie J was diagnosed with early breast cancer in June and underwent surgery soon after. She later announced that the cancer had not spread.

Kate, who went public with her own cancer diagnosis in March 2024, announced she was cancer-free that September. In a statement posted to X, she wrote, “I cannot tell you what a relief it is to have finally completed my chemotherapy treatment. Doing what I can to stay cancer-free is now my focus.” She noted, however, that recovery was ongoing: “Although I have finished chemotherapy, my path to healing and full recovery is long, and I must continue to take each day as it comes.”

Rebuilding Her “New Normal”

The evening also marked Kate and Prince William’s first red carpet appearance together in two years. Since completing her preventative chemotherapy, Kate has slowly resumed her public duties and has spoken openly about the emotional adjustment that comes after treatment.

In July, she reflected on the challenges of reentering normal life, saying, “You put on a sort of brave face, stoicism through treatment. Treatment’s done, then it’s like, ‘I can crack on, get back to normal,’ but actually, the phase afterwards is really, really difficult.” She added that returning to everyday responsibilities takes time: “You’re not necessarily under the clinical team any longer, but you’re not able to function normally at home as you perhaps once used to.”
