Jason Momoa has shaved off his signature long looks for a good cause.

The Aquaman actor shared a video of his makeover, while it was in progress, to social media on Monday

He underwent the hair transformation to draw attention to single-use plastic

urging people to use recyclable aluminum cans for water instead of plastic bottles.

 he began the video. "Hand me those braids" he said to his hairstylist before he held up his chopped locks.

 he said. "I've never even felt the wind right there," rubbing the short hair on the side of his head.

He urged the use of reusable canteens or aluminum alternatives.

 Momoa founded Mananalu Water, a bottled water company that uses resealable and recyclable aluminum bottles.

The company also removes the equivalent of one plastic bottle from ocean waste with every purchase.

Momoa previously shaved off his beard to draw attention to the cause
