Carlos Alcaraz arrived at the U.S. Open on Monday with a new hairdo.

Actually, he arrived at Flushing Meadows with no hairdo — as in no hair at all, aside from some teeny, tiny specks on his head that come to a widow’s peak.

The world’s No. 2-ranked player was asked about his shocking new look following his 6-4, 7-5, 6-4 victory over Opelka. Alcaraz told reporters that he had simply wanted a haircut before the tournament, but one of his brothers “misunderstood” how to use the clippers.

The resulting mess, he said, left him with no choice but to start over with a clean pate.

“The only way to fix it is just shave it off,” a casual Alcaraz said.

Alcaraz isn’t bothered by the situation. As he reminded the reporters, hair grows back.

“I’m not really into, you know, the hair at all,” Alcaraz said. “So I’m the guy who thinks like, OK, the hair grows, you know? And then [in] a few days it’s gonna be already OK, I guess.”

Alcaraz apparently is not kidding about the speed at which his hair grows. He mentioned it to reporters during the Australian Open, after arriving in toasty Melbourne with shorter locks than usual.

“I discussed with my barber that when I get a haircut… three days later it’s grown out,” Alcaraz said in Melbourne. “So I have to go more often.”

Alcaraz unintentionally provided a demonstration during the French Open, where he first sported a rather bushy look during his first-round win over Giulio Zeppieri on May 26.

Two days later, however, Alcaraz returned to the court for his second-round match against Nuno Borges with a ‘do possibly (but probably not) inspired by Moe Howard from the “Three Stooges.” Alcaraz told befuddled reporters after the match that he “had to do something” about his hair and beard, so he flew in his personal barber.

A mere 11 days later, when Alcaraz defeated Jannik Sinner in the final match for his fifth major championship, he was back to looking like this:

So if Alcaraz happens to win the U.S. Open championship, like he did in 2022, he might have a lengthy mane while hoisting the trophy at Arthur Ashe Stadium at the USTA Billie Jean King National Tennis Center.

In the meantime, though, some people might continue to respond to his haircut the way U.S. player Frances Tiafoe did when asked about it by a reporter following his first-round victory over Yoshihito Nishioka.

“It’s definitely terrible,” Tiafoe said with a laugh. “He’s my guy, though. It’s funny. I looked at him and I was like, ‘I guess you’re aerodynamic’ … I don’t know who told him to do that, but it’s terrible. From a guy who gets haircuts week in, week out and prides myself on good haircuts, it’s horrendous.”

Alcaraz also laughed when he was asked about Tiafoe’s comment.

“I know he’s lying,” Alcaraz said. “He likes the haircut. He likes it, he told me.”

Others might react like Irish golfer Rory McIlroy, who expressed his full support for the radical change atop Alcaraz’s head while meeting with the Spaniard earlier Monday.

“I like it,” McIlroy told him. “It’s good. It’s a good look.”

Overall, Alcaraz told reporters, reactions have been mixed — and he really doesn’t care either way.

“Some people like it. Some people don’t like it,” he said. “To be honest, I’m just laughing about the reaction of the people. It is what it is. So I can’t do anything else right now, so I’m just laughing about everything that they are talking about my haircut.”
