Jason Momoa has unveiled a huge new tattoo on his head that honours his Hawaiian roots.

The Aquaman star is known for his long locks but recently shaved off some of his hair to raise awareness of the environmental damage caused by single-use plastic.

And the Hawaii-born actor has now replaced it with an intricate inking that pays tribute to his heritage.

Momoa, 43, revealed the new etching in a video on Instagram which saw him boarding a Hawaiian Airlines flight to New Zealand.

The star told his followers he was "proud to be Hawaiian".

He then said he had "something special" for them and whipped off his hat to show the new tattoo.

The marking runs down the side of the star's head and onto his neck in a triangular pattern.

Momoa also shared snaps on Instagram which appeared to show the tattoo being done.

"Honored to be a part of this, powerful moment in my life," he wrote.

In the images the star is seen on a bed while the pattern was etched onto his head.

The star's team told JustJared.com: “He got his head and neck tattooed. It’s a huge piece, it’s related to his Hawaiian roots and culture."

Momoa's fans were blown away by the new tattoo, posting messages on Instagram saying it was "awesome".

"This is so cool and this traditional art of tattooing is so amazing... respect," said another.

One posted: "Really cool and very special to be connected with your heritage and ancestors in this amazingly beautiful way!"
