Poor hair brushing in sepearate instances? I don’t think so.
I challenge you to get a hold of every picture showing this feature and to compare them for consistency. You'll see that each image will show a different "scar".
One image I've seen shows a crooked line going down the side of his head. The other two images I've seen show a more or less straight line going through his scalp, but even those two are not identical.
If the man makes this mistake once, it's because of his peculiar grooming habits. You can expect and predict that he will repeat it.
Seriously, this is much ado about nothing.
