I work t a preschool and had my first encounter, ever, last year with lice. I started doing research and became super paranoid. Thankfully our daycare bombed the whole place the night of when we found out a kid had lice and did not let the kids return until thy were nit free.

In my research, lice like clean non-product-y hair. They also do not like coconut, lavender, or tea tree. So if you use oils or products in your hair, more than likely you'll be ok. These, IMO, are healthy preventives than the lice poison.
