Prince William has a known sense of humor about his hair—or lack thereof. In September, he joked with a hairstylist, while on a royal visit, about his mostly bald head saying, “I don’t have much hair. I can’t give you much business.” And at a royal appearance on Thursday to support the Step Into Health program (which helps employ veterans in the N.H.S.) on Thursday, the prince revealed that he now has even less business to offer that hairdresser, debuting a mostly shaved head.

William’s close military shave, was, per E! News, reportedly noticeable to those he met at the event. But this hair moment is certainly not the first time that the royal’s hair has become a topic at a public appearance. In 2014, at a shearing demonstration at Sydney Olympic Park in Australia, Kate Middleton took a jab at her husband’s thinning hair. When Lyn Crejan, a farmer from South Wales, showed the royal couple a tuft of wool similar to William’s shade, the duchess made a wisecrack.

“The Prince was interested in the alpaca and as I showed it to them, the princess said he should put it on his head," Crejan told reporters. “She said, ‘You need it more than me,’ and pointed to his head and he laughed.”

But one’s brother is always the one armed with the best jokes. When he spoke to the BBC about his 2011 wedding toast for William, Prince Harry was sure to include a comment about his balding bro.

“But it's me and a couple of his friends, and between the three of us, we’ll make sure that we dig him in the ribs a few times and embarrass him,” he said. "And make him lose some hair.”
