If I'm not mistaken, nope. There is an explanation about his white hair, and he would have had them only after his return from the rift.
It's an important plotpoint that's going to be explained later in the novel, don't worry, you'll see a lot of white-haired J
Uh, why didn’t J have white hair in the past when he met LS?
I’m pretty sure in the novel he had white hair when he awakened?
