I know stories back when anti-lice medicine was expensive and rare (1960s-1970s), guys would shave off their head but girls couldn't, so they would pour benzine

I know stories back when anti-lice medicine was expensive and rare (1960s-1970s), guys would shave off their head but girls couldn't, so they would pour benzine on their hair instead to get of the lice, and take several days off the school for the smell to go away.
