Opinion of Maran HaRav Eliashiv
At Maran's behest HaRav Aharon Dovid Dunner, shlita, a
dayan in London, traveled to India to clarify
practical aspects of wigs made of human hair in India.
According to the inquiries he made, hair cut off in the place
of idol worship in Tirupati is halachically considered an
idol-worship offering (tikroves avodoh zora).
Therefore Maran HaRav Eliashiv, shlita, ruled one may
not use wigs made of human hair from India.
