Yes - it's still an issue. I get a notification from the kids' school at least once a year. I wash my daughter's hair with tea tree oil shampoo, keep her hair in braids, drill her on the rules: don't share hats, barrettes, hair bands, etc. I dealt with it once years and years ago with my oldest (who is now in her 20s) and it was a nightmare. I never want to go through it again, so I am super paranoid about it.
