Performer Justin Bieber is under fire for his latest hairstyle: dreadlocks.

What are the details?

Bieber, who debuted the new look Monday on Instagram, took flak for the hairstyle after many people said that he was guilty of cultural appropriation and racial insensitivity by wearing the hairstyle.

According to USA Today, Bieber has previously said that he's "very influenced by black culture," but many social media users weren't happy with his new look.

One user, as highlighted by the outlet, wrote, "Listen @justinbieber I don't care how long I've liked you, this is cultural appropriation and i don't like it."

Another added, "Justin how are you gonna preach that you're an advocate for black people and then keep appropriating them? Makes sense buddy."

A third user said, "Justin Bieber is wearing locs right now. I don't like it because black folks who were locs are still discriminated in the workplace for wearing hair that comes natural to them. There are laws that exist that actually prohibit."

The 27-year-old artist released his sixth studio album, "Justice," in March.

In June, Bieber admitted on social media that his "style," as well as how he sings, dances, performs, and dresses "have all been influenced and inspired by black culture."

"I am committed to using my platform this day forward to learn, to speak up about racial injustice and systemic oppression, and to identify ways to be a part of much needed change," he said on Instagram at the time.

What did some professionals say?

On Wednesday, The Guardian reported that Stephanie Cohen, co-founder and legal and political organizer at Halo Collective — which is a natural hair organization, according to the outlet — said, "When I see a white person in mainstream media sporting a black hairstyle, it makes me angry. I'm angry because this standard does not exist when a black person simply wears their hair in this way. You can't just wear something so historically significant and ignore the struggles behind what the hairstyle purports."

Cohen added that the performer had "no right" to wear dreadlocks or any other typically ethnic hairstyle because he is white.

“My reasoning and understanding of someone wearing something not specific to their culture or ethnicity is that if they cannot speak for black or minority rights [and] be a consistent ally — then they have no right to wear something like locs," Cohen said.

Irene Shelley, who is editor of Black Beauty and Hair magazine, added, “I think why people are annoyed with Justin Bieber casually wearing locs is that it's seen as not respecting the origins of the style."

"People still face hair discrimination and stigma for their hair choice," Shelley added. "You can face discrimination by your employer or school. [Bieber] is seen as a dilettante, a person who's dipping his toe in the culture, without any real commitment or knowledge of the style's history."

Anything else to know?

As highlighted by Billboard, Bieber faced similar criticism in 2016 after wearing the controversial hairstyle.

At that time, Bieber responded to backlash in a social media video by saying, "'Dude you gonna do anything with your hair, or are you just gonna leave it like that, dude?' Yeah, some girl came up to me and she was like, 'I love you, Justin, but like, that's like my least favorite hairstyle of yours.'"

He captioned the video, "Being weird is fun' if u r not weird I don't like you."
