You can buy an electric nit comb that zaps the lice. But its the eggs you have to concentrate on getting rid of. You will have to wet comb for up to a week to ensure the eggs are gone. Don't forget to wash all the towels, bedding, hats, coats and to check your hair and your partners hair too.
You can also buy a pump spray to use to try and prevent lice coming back, but you can only use it once you are sure the headlice are gone.
If you do use a chemical treatment (use gloves) you will still have to wet comb with conditioner for up to a week.
