Hi Rapture, I think we can apply 1 Corinthians 8 to wigs as well as food that may have been offered to idols:
4 So then, about eating food sacrificed to idols: We know that “An idol is nothing at all in the world” and that “There is no God but one.” 5 For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), 6 yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
That is verses 4-6, but you might want to read all of chapter 8 for a bigger picture. Romans 14 is good as well. God bless!
