Pulling out hair

I’ve developed a significant anxiety around accidentally pulling scalp hair out (I don’t mean hair that has reached the end of its cycle and is meant to come out, I mean active anagen hair. It can happen, for instance if hair gets caught in something like a zipper).  To help put this phobia into perspective, do you have any insight on the likelihood that accidentally pulled hair grows back? If I were to reach up and pluck a healthy, anagen scalp hair, which percentage of the time will it grow back?  I’m aware that repeated pulling out the same hair can cause permanent damage, I mean pulling that occurs only once.
