Jason Momoa is showing his love for the environment by shaving his head!

The Dune star, 43, took to Instagram on Monday and toasted "new beginnings" by getting his famous locks chopped off.

"Aloha, everyone," he began in the video, before he added, "Hand me those braids."

As he held two long pieces of cut braided hair, Momoa proceeded to talk as clippers made mulch of his shoulder-length hair.

"Shavin' off the hair… doing it for…" he said before pointing to the newly shaved side of his head. 

"I've never even felt the wind right there!" he added.

"Doing it for single-use plastics," Momoa continued.

"I'm tired of using plastic bottles, we gotta stop, plastic forks, all that s---, goes into our land, goes into our ocean.

"I'm here in Hawaii right now, and just seeing things in our ocean, it's just so sad.

Please, anything you can do to eliminate single-use plastics in your lives.
