operating theater isint totaly sterile, anyway i woudnt bother saying antyhing,
im sure if it was such an issue, or if there were historical issues with hair peices,in the "o.r,
many hospitals wordwide would have updated there policy and make patients aware of this.

no one to my knowlege has written a peice appearing in the lancet or any emminent periodical
regarding hair systems and surgery,unless its youre head there operating on.
