It's the end of an era!

Lin-Manuel Miranda ended his run in "Hamilton" on July 9 -- and immediately afterward chopped of his signature long locks, which he'd grown out to play the role in the musical he created.

"Teach 'em how to say goodbye…" he captioned a black-and-white photo revealing of a piece of his hacked ponytail on Twitter at 10:19 p.m., just after the cast's curtain call.

Afterward, the 36-year-old Tony (and Grammy, Emmy and Pulitzer Prize) winner publicly debuted his freshly shorn new look at the show's afterparty, along with a Muhammad Ali-printed shirt.

Overnight, his transformation was dubbed "The Hamilcut" by some social media users, reports People, which also explained that Lin-Manuel's replacement in "Hamilton," Javier Muñoz, will wear a wig when he steps into the role.

Lin-Manuel has said he plans to occasionally return to "Hamilton" in the future -- so it seems like he too will don a wig when that happens.

The big cut comes just a few days after the in-demand Broadway star recorded a song with Jennifer Lopez to honor the victims of the Pulse nightclub shooting in Orlando.

He and J.Lo will perform their track "Love Make the World Go Round" during a "Today" show summer concert series appearance on July 11.

All proceeds from the single, which is available on iTunes, will benefit the Hispanic Federation's Proyecto Somos Orlando, an Orlando crisis management and mental health program, reports "Today."
