am23 – I think the point is that NOT ONE PERSON in the yeshivos mentioned here or actually anywhere wears a wig. The rabbonim in the yeshivos teach Torah. You have to pick your Rov who is someone you go to for halachic issues. If you are against a woman wearing a wig, then make sure that your Rov holds that way and then you will make sure to find a shidduch with a girl who does not care about wearing a wig. There are plenty of girls, even baalei teshuvah, who do not care about wigs.
Just as an aside, any yeshiva associated with Toldos Aharon is not going to be for a baal teshuvah.
