Kate Middleton Just Dyed Her Hair Even Blonder

There are few heads of hair on the planet more discussed, dissected, and photographed than Kate Middleton’s. Long before she was the Duchess of Cambridge and the future queen consort, Prince William’s then girlfriend and enviable long, brown hair became a staple in the world press.

Since then, royal watchers (and beauty fans) have clocked every style and color change Middleton has made. Her 2016 bangs were hotly debated (I loved them and sort of wish they’d make a comeback) and some theorize that certain changes in her hair indicate a pregnancy. Lately she seems to be having fun playing with her color.

Last month she debuted some gorgeous honey-blond highlights while dropping Prince George and Princess Charlotte off at Thomas’s Battersea for their first day of school.

And at Wednesday’s royal engagement at the Natural History Museum in London, it appears she’s changed her hair once again. While it’s hard to tell what is hair color and what is lighting, fans online are speculating that the duchess has gotten even more highlights since last month’s update. Because royals aren’t like other celebrities, we rarely get to learn the details of their beauty routines from their glam squads or the duchesses themselves—so it’s unlikely we’ll get a confirmation. But the photos more or less speak from themselves. Lighting, color lifting, whatever the effect, her hair looks shiny, vibrant, and healthy.

For comparison’s sake, here’s what Middleton’s hair looked like last week during an event she attended with William at the Aga Khan Centre, ahead of their royal tour in Pakistan on October 14.

Middleton’s color was definitely more brunette when attended she Wimbledon with her sister-in-law Meghan Markle this summer.

Please, Kate: Won’t you share your secrets with us? Maybe Meghan can fire up The Tig again, but make it royal—and you can both divulge all your beauty secrets? Maybe the queen won’t even care? (JK: This is never happening.) In the meantime I’m guessing these photos will end up in the hands of colorists across the globe as clients bring them in for inspiration.
