The royal hairdresser spoke about this.
Prince Harry’s growing bald spot is a concern for royal hairdresser Sam McKnight, who once cut his hair and that of his mother, Princess Diana, he told the Daily Telegraph.
According to McKnight, the prince’s baldness has reached catastrophic proportions and something needs to be done about it.

“He’s got this fluff on his head like a chick that’s just hatched,” he says. “It’s just awful. He looks like a geography teacher from the 1950s.”

McKnight said that in Harry’s place he would have done something different. When his baldness became impossible to hide, he simply shaved his head. “I’m 69 now, but if I were his age, or 20, 30, even 50, I would have had a hair transplant right away,” the barber said.
Aging is what we see in Harry. He looks like he’s in his 50s. Maybe he doesn’t care. It’s great when someone doesn’t care about these things. But if he had a hair transplant, it would give him his youth back.
