Bye-bye, beard!

Hirsute star Jason Momoa no longer sports the look fans have known and loved ever since his season one stint on HBO's "Game of Thrones."

On Wednesday, the actor uploaded a video to YouTube, in which he sheds his facial hair for what he considers to be a good cause.

The four-minute video opens with Momoa hiking through a landscape littered with plastic bottles. While speaking out about the environmental impact of plastics, he slowly shaves off his beard.

"I think 2012 is the last time I shaved," he muses as he walks along. "I just want to do this to raise awareness that plastics are killing our planet — and I think I have a solution. I don't want to bitch about it. There's only one thing that can help our planet and save our planet, as long as we recycle, and that's aluminum."

Momoa has teamed up with Ball Corporation for its "infinitely recyclable" campaign to promote the use of the 100% recyclable soft metal in lieu of plastic for packaging beverages — in this case water.

"Goodbye DROGO, AQUAMAN, DECLAN, BABA!" the 39-year-old wrote in the clip's caption, referencing some of the characters he's played over the years. "I'm SHAVING this beast off, It's time to make a change. A change for the better...for my kids, your kids, the world. Let's make a positive change for the health of our planet. Let's clean up our oceans our land. Join me on this journey. Let's make the switch to INFINITELY RECYCLABLE aluminum. Water in cans, not plastic."

Behold the final result (not for the environment — just for his face).

Of course, this isn't the first time he's been beardless on-screen.

Back in 2011, filmgoers got a chance to see his strong jawline when he played the smooth-chinned titular character in "Conan the Barbarian."

Though his beard is no more — for now — don't expect his long locks to go away anytime soon.

Just four months ago, the "Aquaman" actor told The Daily Telegraph that getting a trim could land him in trouble with spouse Lisa Bonet.

"My wife would leave me if I cut my hair, so I just don't cut my hair," he said.

Not even for "the health of our planet."
