He recently shared a series of photos debuting a look that closely resembles dreadlocks which is when sections of hair fall into rope-like strands. It's also a style closely associated with and worn primarily by people of color.
The style is also referred to as "locs" or "dreads."
While the singer made no reference to his hair with the photos he posted, others were quick to comment.
"It's really disappointing to see you with dreads, I thought you educated yourself, @mimisreighn said.
Another Instagrammer @newshaileybieber chimed in saying, "this is cultural appropriation... I know you can do better."
What is cultural appropriation?
Cultural appropriation, a term often used on social media, is when someone or a group from one culture is accused of taking elements, trends, styles or anything related from another, often underrepresented culture.
In Bieber's case, many fans have also come to his defense saying that his look doesn't fall under cultural appropriation.
"This is not cultural appropriation, as he didn't CLAIM he invented it, nor does he financially benefit from having this hairstyle," said @dona.co.uk in a comment.
Another simply said, "let him do whatever he wants with his hair."
The "Peaches" singer was also previously accused of the same in 2016 when he wore dreadlocks as well as cornrows. Bieber reacted to the backlash saying "it's just my hair," according to The Fader.
Last year, Bieber shared how Black culture has influenced his career.
"I am inspired by black culture," he wrote in an Instagram post. "I have benefited off of black culture. My style, how I sing, dance, perform, and my fashion have all been influenced and inspired by black culture."
He said that by sharing that he would be committed to using his platform "to learn, to speak up about racial injustice and systemic oppression, and to identify ways to be a part of much needed change."
