While intense heat can kill lice, standard straighteners miss most of them and their eggs, leading to continued infestation and potential scalp damage from repeated high heat, making dedicated lice treatments and wet combing the best approach.

The main focus should be on treating the infested person, but washing bedding in hot water (over 130°F/54.4°C) and using a hot dryer is a good practice to be safe.
