One item that is often overlooked in preparing for a collapse situation - where hair and beards can grow long and so can the interval between showers, is the humble nit and lice comb.
So take a look at the Shantys nit and lice comb, and watch their video. (I have no connection whatsoever with this company)

JWR Replies: Reviewing the history of the 20th Century, one could summarize: "War is hell, but it is also lousy." Whenever people live in close confines, the spread of lice increases dramatically. Just imagine your household, after The Crunch, with an extra 10 or 12 relatives and friends sleeping on the floor. That would be the ideal breeding ground for lice. So Andre's point is well taken!
