Let me explain about lice
. It can be passed for person to person by a captian's hat. I have seen the lice bugs it's not pretty. Shoot I played with one on this lady's head, until I realized what I was doing.
Then I told the lady I could not cut her hair and sanitized the heck out of my station, comb, cape, and chair. That is one of the things I don't miss about cutting hair. Okay who is scratching thier head right now.
