Bill de Blasio has apparently been testing out changes to his image after earning the title of New York City’s worst mayor.
De Blasio was spotted in Brooklyn last week with a head of what seemed to be dyed-brown locks, sparking speculation that he was trying to reinvent himself post-congressional campaign or appear younger for his Harvard teaching gig.
The 61-year-old pol — who previously wore a slightly longer gray ‘do when he was in office — was seen leaving his Park Slope home with the closer-cropped dye job Friday afternoon.
He was spotted at Bar Toto, one of his family’s favorite local Italian joints, along the way.
A former staffer quipped to The Post that while de Blasio was in office, ”When it came to his hair, it wasn’t the color that was the problem, it was the mullet length.”
The source suggested that his old boss may have recently opted for darker hair to seem more hip at Harvard University.
The political has-been, who notoriously failed both his bid for president and Congress, began teaching as a fellow at Harvard this fall.
His courses at the School of Public Health and Institute of Politics focus on his time at the helm of the city during the COVID-19 pandemic and implementing universal pre-K.

“If you hang out on a college campus, you’ve got to blend in more?’’ the ex-staffer suggested when asked about de Blasio’s brown ‘do.
Either way, “It’s very strange,’’ the former mayoral worker added.
Other ex-staffers weren’t sure why the former mayor had apparently taken a lesson from the school of hairdressing of one of his predecessors, Rudy Guiliani.
Former city Mayor Giuliani was famously caught on camera with brown hair dye running down his face during a press conference in 2020 about alleged election fraud.

Some people speculate the hair change could be to his teaching gig at Harvard. Paul Martinka“L.O.L.,” a former de Blasio staffer told The Post of his old boss’s recent apparent dye job. “I feel like the salt and pepper wasn’t a bad look for him, But Bill de Blasio is gonna do [Bill de Blasio].’’
Then Sunday morning, de Blasio’s locks were back to being more mousy gray at a Brooklyn street-renaming ceremony in honor of a local former educator.
During the event, the 6-foot-5 former mayor ended up scaling the side of a street pole with the new signage to reach the rope that would unveil it as Sarita Rein Way.

He looked happy to play the hero, smiling the whole time while dressed in a blue suit and green quarter-zip sweater.
He was the one who pulled the rope for the new sign to be unveiled.
When approached by The Post afterward, de Blasio only said, “Brother, I’m just going now. Can’t help you now, brother. I’m talking to a council member.”
