2. Tea tree oil works, too
Another effective home remedy for treating head lice is tea tree oil. This oil contains two important ingredients: cineole and terpinene. Both ingredients are natural insecticides, which means that they have the ability to kill all types of bugs and insects, including parasitic head lice. In addition to smothering and killing the pests, tea tree oil also lubricates the hair, making it more difficult for lice to attach to it. To use this home remedy, apply a few drops of tea tree oil to an all-natural shampoo. Wet your hair, apply the shampoo, and work up a lather, allowing the suds to sit in place for up to 30 minutes. Comb through your hair and rinse the shampoo out.
