• Kate Middleton briefly went blonde over the summer, sending royal watchers into an absolute spiral.
  • Sources at the time claimed her hair was simply lighter thanks to the sun on vacation in Greece.
  • Kate has finally spoken out about her lighter hair after being asked about it at an event.

Remember back in September when Kate Middleton stepped out at the Natural History Museum gardens with Prince William, and seemingly debuted a new blonde color?

Kate just shared the reason for her lighter hair, claiming that it was from spending time in the sun. Apparently she was asked about her hair during an appearance at the Royal Variety Performance at the Royal Albert Hall earlier this month, when actor Su Pollard said, "I like your hair, it looks a lot lighter." According to Hello Magazine, Kate responded, "It used to be brown, but it's gone light in the sunshine."

This echoes what sources told the Daily Mail back in September, with stylist Sarah Gadston saying, "After a sun-soaked holiday in Greece, Kate returned not only with a refreshed spirit but also with naturally lightened hair. 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."

Celebrity hairstylist Adem Oygur added, "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 color. 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."
