regarding todays sheitels being our “mesora”: (from the book “Adorned with Dignity” by C. T. Friedman)
“I Have to Follow My Mesorah”
The yetzer hara will try to convince us that we cannot deviate from the tradition of our family, and we have to follow our mesorah. Let us honestly ask ourselves, “What type of sheitel did my grandmother or great-grandmother wear? Was it as long, flowing, and natural-looking? Surely not; it was short, stiff, and wiggy-looking.”
(Moreover, we need only go back a few generations until most of us will discover that either our great-grandmother, great-great-grandmother, or a previous ancestor wore a kerchief as a head-covering instead of a sheitel. This head-covering dates all the way back to Sarah Imeinu. As mentioned earlier, this tradition was broken due to the horrors of the Holocaust and the modernization of some communities.)
When a woman upgrades her level of covering the head, she brings nachas to Hashem and to her deceased ancestors in Shamayim. This will serve as as an aliyas neshamah for her grandparents and as a zechus for her and her family.
On pg 80:
“We support and bless those women who have returned to the age-old custom of covering their head with a kerchief instead of a wig in order to fulfill the opinion of all poskim…and especially in today’s times when many of the contemporary wigs are not in line with the guidelines of tznius.”(Letter signed by Harav Shmuel Halevi Wosner zt”l; Harav Lipkowitz; Harav R’ Hager, Rebbe of Viznitz; Harav Karelitz; Harav Shmuel Aurbach (in name of his father, Harav Shlomo Zalman Auerbach zt”l); Harav Gestetner, yb”l; Harav Elyashiv zt”l. )
