When my child was young, we experienced a continual breakout at her school. A parent told us to use mayonnaise because the medicine was getting expensive. We Tried it, and it worked. Poor mayonnaise in dry hair, strap a plastic bag on the head for done time, then add it off and dry it. Now this doesn't help work the comb pay, but at least it kills the critters and eggs.

Put mayonnaise in dry hair, wrap a plastic bag on the head for some time, then wash it out and dry hair. Now this doesn't help with the comb part, but at least it kills the critters and eggs.
