It turns out, he had a pretty emotional reason why.
Walker, who showed the haircut on Instagram live, explained why he started growing his hair out and switching up the colors frequently as a kid in an Instagram post on Thursday night.
Walker shared he was sexually assaulted, raped and abused when he was in the fifth grade. While that was happening, Walker realized that his hair was something he could control — so he started having fun with it.
“I was sexually harassed, raped, abused, I even got accustomed to it because being at that age you don’t know what is what,” he wrote, in part.
