Hair dryers

An old-fashioned bonnet dryer killed nearly 89% of nits but just 10% of lice, while a blow dryer using direct heat got rid of nearly 98% of nits and 55% of lice. So use a hair dryer on freshly washed hair to increase your chance of eradicating the little buggers.

But never use hot air after applying a chemical lice treatment. Some may contain flammable ingredients.
