Kate Middleton and Prince William have been pretty out of the spotlight lately thanks to the summer holidays, with Kate's last official appearance being back in mid-July. But she and William were just papped heading to church in Balmoral with their kids, and Kate seemingly debuted brand new blonde hair.

Soooo, did Kate take the plunge after years of being a brunette and dye her hair blonde? Maybe, but the Daily Mail spoke to an expert who thinks Kate's hair was mostly lightened by the sun during her lengthy vacation in Greece.

"After a sun-soaked holiday in Greece, Kate returned not only with a refreshed spirit but also with naturally lightened hair," stylist Sarah Gadston tells the outlet. "The combination of sea air, sunshine, and saltwater had gently lifted her hair to a softer shade—creating the perfect starting point for her next salon visit."

"As Kate embraces the natural changes that come with aging, such as the increasing presence of grey strands, she’s made a thoughtful shift in her hair color strategy," Sarah adds. "Rather than covering grays with darker dyes—which often require more frequent maintenance—she’s opted for a lighter, blended tone. This approach not only gives her hair a softer, more natural appearance but also helps camouflage grays in a subtle, low-maintenance way. Thanks to her time in the Greek sun, Kate has found a new, more effortless hair color that flatters her features, respects the health of her hair, and celebrates the beauty of aging with confidence."

Meanwhile, celebrity hairstylist Adem Oygur noted, "The Princess of Wales and her family are reported to have spent part of the summer holidaying in Europe, where long days in the sun and sea naturally lift and brighten hair colour. Combined with the UK’s unusually warm summer, it’s easy to imagine that her lighter tones could be the result of a natural sun-kissed effect rather than a deliberate change."
