Are any home remedies effective at getting rid of head lice?
Occlusion therapy, nit combing, and hair removal have not been proven to be fully effective in completely eradicating head lice.
Home remedies that have been tried include vinegar, mayonnaise, petroleum jelly, olive oil, butter, rubbing alcohol, and prolonged water submersion. These all fail to eliminate infestation, because these therapies do not kill all of the eggs or lice. This is believed due to the specialized way the parasite "breathes."
Hair removal has never been proven to be effective, but since the louse requires a hair shaft to lay its eggs, it should prevent the lice from multiplying. This is not always considered a desirable option for many children.
