The Nazi skinheads co-opted skinhead. After the Geraldo Rivera episode everyone I knew let their hair grow out because they didn't want to be associated with that shit. Before that there were only a few isolated scenes where you'd see Nazi skinheads. Cutting off your hair was popular in the hardcore punk scenes because it was contrary to the long feathered hair popular in the 70's and 80's plus it was a lot easier than trying to get a Mohawk to stand up straight. That took a whole can of hairspray and we were all broke.
