Cassandra,
I first thought that Bruno was possibly utilizing the old "hot comb," an innovative hair styling device of the late 1960s. (Incidentally, an extremely useful device that Nicholas Blair, no doubt, put to very good use during his time down "below.")
However, after viewing Bruno's "beehive" hairstyle again, I'm reminded of the practice of "conking" that the late Malcolm X wrote about in his "Autobiograhy of Malcolm X," a tome, I'm sure, we all read as college freshmen many moons ago. So, there you have it, Bruno "Conk Job" Hess!
