Slonimer – no need to go research Newspapers I will quote soon the Poskim in those times, in regard to Russia Czarist. Yes – the fact was that it did prompt that most Charedi women opted to go uncovered. Not everyone was able to afford a wig.
Other customs were banished as well due to the Gezeros, e.g. there were many places were married women shaved their heads, the Netziv speaks about it Emek Shailah – it all came to an end then.
I think only some Hungarian chasidim still do that…
