I suspect that would be parts of the subject's hair. As such, I would be tempted to leave them as they are: they're a part of whom this person is.
I too have been thinking of a square crop, but not quite in the manner that is most obvious. This image clearly needs to have the space to camera left to work. To keep this, but also to crop square, you need to crop from the top rh side of this image as well, thus moving his face into the tr corner of the image.
Basically, use the space above the hat as your guide, and crop from the right to leave only a similar amount of space on that side. Now, with that space defined as your top and right edges of the image, you can crop square towards the bottom left.
As a different idea, I would like to see you bring just a very small part of his clothing and body into play: just a wisp, a hint of what he's wearing ... rather than total black. It should just be there - a very small amount of shadow detail.
