Yes. Coca Cola will get rid of lice if you wash you or child's hair with the Coca Cola.
To get rid of head lice with coca cola take about a liter of the coca cola and pour it a little bit at a time onto your hair and massage it into your hair. You also need to add some eucalyptus oil to your hair along with the Coca Cola for it to be effective at killing the head lice.
You then leave the coca cola and eucalyptus oil in your hair for an hour and then you can wash your hair with shampoo.
You also need to use a lice comb to get the nits out of the hair otherwise you risk the lice coming back.
