This question already has an answer here:

In my first yeshiva (which was a Chabad yeshiva), students would place loose hairs that had fallen from their beards into sforim. In my second yeshiva (which was a Litvak yeshiva), my rebbe made a point of blowing them out of books if the book was open and he saw one there. Where did this custom of placing hairs into sforim come from? How widespread is it? How widespread is opposition to it?

  • How widespread is opposition to it? Probably about as common as opposition to hair in one's soup. Most people find this repulsive, and therefore recognize the imperative of accommodating those who find this repulsive. – mevaqesh Dec 2 '16 at 1:43
  • How widespread is it? How do you expect us to demonstrate this? || Seems like Jews not Judaism, anyway. – mevaqesh Dec 2 '16 at 1:44
