“A weekend away,” Kourtney captioned the post, which quickly garnered more than 800,000 likes and a flood of comments. The majority were positive, with many complimenting Reign on his “beautiful” blonde locks.
"His hair is the best!” one user wrote. Another added: "Reign is a beautiful boy and we all, well mostly all of us, love his hair. It's a part of his personality now."
On the flip side, a few people took issue with his tresses –specifically, the fact that Kourtney had let his hair grow so long.
"She really needs to cut his hair," one comment read.
Needless to say, the negativity didn't go unnoticed. Kourtney quickly replied: "She really need to not worry about kids that aren't her own. He is a happy boy." The expert-level shutdown amassed over 3,135 likes, with fans rushing to defend the reality TV star’s right to make parenting decisions without the public weighing in.
"Amen. His hair is gorgeous and I'm a little envious to be honest," one wrote. "Never cut his hair (unless he wants to)," a second user urged. "He is a long-haired beauty."
