To get rid of head lice, Health.com recommends using several methods and applications of treatment, such as combing out nits with a fine-toothed metal comb and applying pyrethrum shampoo, one percent permethrin lotion or ivermectin lotion to the scalp. Doctors can prescribe strong lotions with benzyl alcohol or spinosad as the active ingredient. Some individuals find relief from using mayonnaise, hair gel, vinegar and olive oil as homemade topical treatments.
Using a hair dryer is proven to kill off a great deal of nits, so Health.com recommends that individuals use the device after a bath or shower to increase the odds of eradicating the pests. Health.com urges individuals with lice to remain diligent in trying to fight a head lice infestation. When one method does not work, it is a good idea to try another until all adult lice and eggs are gone. Repeat applications kill off new adult lice that hatch from the eggs and help prevent an infestation from cropping up again.
Parents and caregivers can overreact and feel that they must sanitize the entire home, but Health.com explains that head lice remain mostly localized to the hair and cannot live for more than one or two days outside of the scalp. Adult head lice are incapable of moving around easily, and the eggs are strongly attached to the hair shafts.
