Prince Harry ‘very likely’ using $40 product to thicken hair: expert

Prince Harry’s patience with the royal family isn’t the only thing that’s getting thinner.

A new headshot of the 38-year-old Duke of Sussex debuted Monday on the website of the mental health “transformation” firm BetterUp — shockingly, his hair was thicker and darker than usual.

Now, a leading hair loss and hair transplant adviser is sharing what Harry might be doing to look so, uh, hairy.

“I think it’s very likely he is using Nanogen hair fibers,” Spencer Stevenson, founder of SpexHair, told The Sun.

“This is an A-list celeb secret and helps many when they need to thicken their hair up instantly for a photo shoot or a movie.”

Nanogen hair fibers are lightly sprinkled on areas where thicker hair and volume is needed. Fingers are used to blend in the fibers.

A can retails for about $40 on Amazon.

“I think Harry’s hair shows signs of being helped as it looks darker and thicker,” Stevenson added.

The Post reached out to representatives for Harry for comment.

Some fans speculated that he could be using Photoshop in the new snap, with one person on the platform X comparing him to noted photo editor Khloé Kardashian.

Over the past few months, Harry has been spotted with thinner and brighter-looking red hair, including when he was photographed shopping for his wife, Meghan Markle, 42, in Tokyo this month.

Hair appears to be a sore subject for Harry, who took a jab at Prince William’s receding hairline in his January tell-all memoir, “Spare.”

He called his 41-year-old older brother’s balding head “alarming” and “more advanced than mine.”

The latest hair-y controversy follows reports that Harry will meet for “peace talks” with his father, King Charles III, next month.

However, Sussex sources denied the rumor to The Post on Sunday.

One expert labeled it a “publicity stunt.”

Publicist Matt Yanofsky told The Mirror that the so-called summit seems to be a PR move more than a heartfelt meeting.

“This is another story point … which is great for the entire family [and the viewers at home],” he said.
