Catherine, Princess of Wales was joined by her husband, Prince William for a visit to London’s Natural History Museum, which she is patron of. It is the couple’s first royal engagement since the summer holidays.
It was first speculated that the Princess of Wales might have changed the colour of her hair when she was spotted travelling to church through her car window. However, it was only when she stepped out at the National History Museum on Thursday September 4, that the Princess of Wales had decidedly to go somewhat blonder in colour.
Over the years, it would seem that Catherine Princess of Wales has experimented with different hairstyles but when it comes to the colour, she has in recent years opted for a more bronde shade, which is basically caramel coloured, a mix of blonde and brunette.
It would seem that perhaps summer has ended, the Princess of Wales might have been tempted to go even blonder. British Vogue reported “Call it a back-to-school revamp or just a bucking of the season’s usual trend to go darker as the nights draw in, but Kate was clearly in the mood for a refresh to mark the new season.”
NationalWorld takes a look back at some of the Princess of Wales’s most memorable hair looks, including her wedding day back in 2011.
