This is the translation of a letter written by a top talmud of Rav Elyashiv zt”l:
(Opening paragraph praises those who have raised the topic of today’s wigs, which is described as pritzut and a gateway to sin).
“Many times, we heard from Rav Elyashiv zt”l, how pained he was by this great breach, and how much he encouraged Jewish women to go with a mitpachat, which he considered “Glatt”, because even the old wigs, were a matter of controversy among the poskim, and from then on to today, the Yetzer Hara has not rested to produce different styles of wigs, the common denominator of which is to stimulate the Yetzer Hara and cause the men of Israel to sin, and it is a double obligation for us to cast aside this pritzut, and for sure anyone who is a Ben Torah– Heaven forbid that he should be lenient in this matter–
and let this be the first stringency that he takes upon himself, especially as (today’s wigs) can create a Michshol for the Rabbim (a pitfall for the masses). And “Ashrei” (fortunate/blessed) is one who separates
himself and who REFUSES to allow today’s wigs into his home. And in this merit, he will merit children who are Talmidei Chachamim and Tzaddikim…
And on this I have come to sign
