Some simple home based treatments that can be use to kill an infestation of lice and nits are:
Wash the hair with a cup of vinegar for a couple of days to kill off the lice and the nits.
Apply some onion juice, on the scalp and hair and keep it for a few hours. Wash the hair with warm water and use a fine-toothed comb to drag out the dead lice and nits from the hair. Repeat it for three days.
Apply a paste of garlic and lemon juice to the scalp and hair and keep it overnight with a towel wrapped on the head and wash it in the morning. Media URL: http://www.simple-remedies.com/home-remedies/lice.html
