Bill de Blasio’s hairstylist says he ‘touched up’ the former mayor with a hair color.

Bill de Blasio’s longtime hairstylist opened up about his new hair-dyeing job on Wednesday while the former mayor stopped by the famed Manhattan barber shop that almost closed its doors forever during the pandemic.

The 61-year-old politician’s hairstylist at Astor Place Hair Stylists, Alberto Amore, told The Post de Blasio that the striking transition from gray to brown locks is simply a slight touch-up that appears much darker in certain lighting conditions.

“We touched up his hair a bit. But the photos released made it look a lot darker than it is,” Amore said. “It’s a brown, tan color.”

De Blasio paid a visit to Amore on Wednesday to celebrate the two-year anniversary after the iconic 75-year-old East Village hair salon was saved from business closure.

Amore, who has been cutting de Blasio’s hair for two decades, said his work has resulted in many different looks over the years.

“De Blasio used to wear an afro, but now he’s like a normal boy, a normal guy,” he said. “I do what he wants. I basically give him a professional haircut – not too long, not too short.”

He added: “He’s past the Afro days. He’s not a young hen anymore. He’s still young, but not that young anymore.”

On the subject of cutbacks, De Blasio was asked by The Post if he regrets leaving Mayor Eric Adams with a massive budget deficit by spending all of the city’s COVID-19 money, expanding the city’s workforce and leaving the city with little funding for new negotiations have left collective agreements.

“I wouldn’t say all of this is the right way to think about it,” de Blasio replied. “Our job was to bring New York City back; Our job was to trigger a recovery. I believe we used the resources we used correctly.”

“Go straight to Broadway! This is a city that’s coming back. I am very proud of what we have done. I’m proud of the public servants who made this possible,” he said.

De Blasio – who arrived 40 minutes later than his scheduled appointment – said he hadn’t looked at the details of the city’s new budget or Adams’ cuts, but said he was glad he didn’t hack pre-K dollars , when he was in charge.

“All I can say is that the focus on early childhood education worked; Pre-K and 3-K worked. Whatever the approach, we have to make sure it’s truly universal,” de Blasio said. “We have to make sure there’s a place for everyone who needs one.”

The beloved hair salon was saved from closure in November 2020 by a group of wealthy New Yorkers who stepped in to save it. Famous clients over the years have ranged from pop artist Andy Warhol to actor Robert de Niro.

Other well-heeled supporters include Mike Bloomberg’s adviser and former Hillary Clinton aide Howard Wolfson, pollster Jeffrey Pollock and gaming mogul Jeff Gural.
