It’s his hill to dye on.
Former Mayor de Blasio — who is no stranger to rocking a new look — cheered on Ben Affleck for stepping into broad daylight last week with a noticeably darker beard and mustache amid his rocky divorce with Jennifer Lopez.
“Do what you do Ben — just keep experimenting, find what works for you,” de Blasio, told The Post, calling his fellow Massachusetts native “an incredibly vibrant, talented person.”
The 52-year-old Oscar winner was spotted last week in Santa Monica, Calif., with the near-black facial hair in lieu of his usual salt-and-pepper hue, less than two months after Lopez, 55, filed for divorce on the second anniversary of their lavish Georgia wedding.
De Blasio, 63, dodged sharing whether the “Justice League” star’s decision to darken his whiskers was actually an improvement on his au natural aesthetic, but gently suggested trying a new color is bound to be “imperfect.”
“My message to any guy is: if some color in your hair, some color in your beard makes you feel better, more power to you,” said the former Big Apple mayor, who slayed his own grays following his short-lived 2022 congressional campaign. “It’s about you, not about what other people think.”
The mayor’s own former staffers panned an early brown dye job the Democrat was first spotted rocking shortly after he started his Harvard teaching gig in fall 2022.
Since announcing his separation last year from his wife of nearly three decades, Chirlane McCray, de Blasio and his darkened ‘do have been spotted on dates with a series of gal pals across town.
In December, he was seen holding hands in NoHo with literacy company founder Kristy Smart, whose husband of 12 years was dumbfounded by the news of the pair’s public fling.
The ex-mayor was also caught getting cozy with another mystery woman during a candlelit dinner in Lower Manhattan in October 2023 and making out with a third the month before at the Empire Rooftop bar in Columbus Circle.
Blaz, however, demurred on whether his dye jobs have helped him play the field later on in life.
“I can’t judge what it means for dating. It’s what I feel comfortable with,” he said.
Deciding to color his hair, he added, was akin to the Jets’ recent decision to axe Robert Saleh as coach.
“It was time to act,” he said.
