Prince Harry's brother, father and grandfather have all been sporting balding heads for a good few years now, but it seems the 34-year-old new father recently joined Prince William, Prince Charles and Prince Philip as the newest male royal family member to seriously start losing his hair.
The famous ginger, who welcomed his son Archie Mountbatten-Windsor earlier this month, has long enjoyed a full head of glorious hair.
Yet as the Duke of Sussex enters his mid-30s and encounters more stressful life events, with his highly publicised marriage to Meghan Markle and the wall-to-wall coverage of their son's birth, his bald patch has increased considerably in size over the past year.
Even William's wife Kate Middleton reportedly makes fun of her husband's baldness.
According to BBC Radio personality Clara Amfo, when she met William and Kate in 2018, the couple joked quite openly about the Duke of Cambridge's hair loss.
"Kate had no qualms making fun of William's hair situation," Clara revealed to HELLO magazine.
"And he took that. There was a lot of banter around that, it was very funny!
"Prince William is the most fun royal that I've met. He's got a lot of banter actually. He's a very funny guy. And the banter between him and Kate—his and Kate's energy is really funny. They vibe off each other very well. They were like a really loving, comedy act."
And Prince Harry also joined in on the fun, once telling reporters: "I think [William] definitely is brainier than I am, but we established that at school, along with his baldness."
Since his wedding to Meghan in May last year, Prince Harry's bald patch has been getting bigger and bigger.
According to experts, this is quite normal and common for men of Harry's age - and sadly it's all down to his royal genes.
Trichologist Anthony Pierce, who is a hair and scalp specialist, says male genetic thinning is a natural process that occurs in about 65 per cent of men around Harry's age.
Whether or not a man goes bald early is purely down to his genetics.
"It's part of a man's secondary sex characteristics, so the same genes that give us our whiskers, deeper voices and muscles. If you have those genetics, hair thinning tends to happen," Anthony told Now To Love.
He said it appears as though Prince Harry, as well as his brother William, have chosen to go down the natural route and steer clear of any treatments.
While it's impossible to completely cure baldness without a hair transplant, there are a couple of ways to slow it down.
"You can't cure baldness unless you do an all over hair transplant, but you can stabilise it to the point where it doesn't get any worse and you can regrow a good percentage of what you've lost," Anthony said.
"There are topical and oral medications available. The oral medication stabilises genetic thinning in 85 per cent of males, so it gets no worse. And then there are topical treatments like gels or liquids which can stimulate hair growth."
But Anthony says men who are thinking of using these treatments should have a full health checkup beforehand.
"I do a full medical assessment beforehand. I don't just assume that it's a genetic problem, because if men have a gut issue or they're low in vitamin D or zinc or iodine, they could swim in these treatment products and it wouldn't make a difference," he said.
"And young men who have a history of depression and anxiety shouldn't take these oral medications."

Anthony says it's important for men like Prince Harry to remember that balding is completely natural.
"It's really important to tell men that even though there are genuine treatments that can stabilise your genetic thinning, this is not a cure, because there is nothing wrong with you.
"It's part of your genetic expression."
