It will have started with the girls.  They always brought nits into class first, or so the other boys said

As father of three girls, the very topic makes me shudder    Years spent in a seemingly endless battle against the nits, first one child then the next, armed only with a nitcomb and a delousing shampoo that the critters were inevitably resistant to.  Fortunately, by upper school, the girls had discovered "product" for their hair.  No louse can survive what a teenage girl puts on her hair.
