Here are the words of more Gedolim:
HaRav HaGaon Rav Shalom Shwadron Zatzal:
And why do they wear a sheitel, not because they want to cover their hair, but because it’s nicer that way. And my grandfather MaHarsham said it is assur to read krias Shema or any word of kedusha in front of a sheitel, and said that a women like this violates a tremendous issur and is doing something against the will of Hashem and those who fear him.”
HaRav HaGaon Rav Yitzchak Isaac Rosenbaum-the Admor form Nadvorna Zatzal
the peah nochris is for vanity and pritzus, to incite the yetzer horah, so men will look at her The Chasam Sofer:
Be careful from the bad of bad women… even with a peah nochris I forbid you with an issur gamur.”
(בצוואתו לבני ביתו)
HaRav HaGaon Rav Yosef Chaim Zonenfeld Zatazal and HaRavH”G Rav Yisroel Salanter Zatal:
Put anyone who’s wife had the chutzpah to wear a sheitel in cherem.
HaRav HaGaon Rav Yehuda Tzadka Zatzal:
A Women who walks with a peah nochris is gaava and and sin with forbidden thoughts rachmana litzlan. Many have been punished for this rachmana litzlan.
HaRav HaGaon Rav Ovadia Yosef zatzal:
One must assur a women to leave her house with a sheitel adamantly . He
Quotes many tens of poskim besides for these who absolutely assured sheitels and says that it’s a mitzvah to publicize the issur, and those that listen will reap tremendous blessing from Hashem. (In all of his awesome Teshuvot)
