Avodah Zarah Wigs II

I found a responsum on the subject of wigs made in India from, surprisingly, a number of years ago. R. Moshe Shternbuch has a long discussion of the various issue in his Teshuvos ve-Hanhagos vol. 2 no. 414 (consider that volume 4 was recently published, so this is an old teshuvah). He concludes that such wigs are assur and that one might not even be able to buy a different type of wig from someone who sells such wigs from India (tofes es damav etc.).

Importantly, he ends by saying that this matter depends entirely on the reality at the time and must be reviewed constantly to determine the actual production flow of wigs and whether it has changed.
