NITS are the bane of every parent's life, but there are some extremely effective natural solutions.
Head lice lay their eggs very close to the scalp, but attached to the hairs so that, as the hair grows, the egg is moved away from the scalp. The 'glue' is extremely strong: the eggs cannot simply be combed out of untreated hair.
A simple base shampoo with tea tree and lavender essential oils added is useful, but washing the hair is not enough. To get rid of lice, massage rosemary and cedarwood hair treatment (£7 for 75g) into the hair.
And coconut oil makes the hair smooth and slippery so the lice lose their grip. After applying, comb through the hair with a fine nit comb and again one hour later. It takes seven to ten days for lice to hatch from their eggs, so it is important to repeat this treatment on a weekly basis until no more lice are present. Bug Buster combs (£1.75) are recommended by the Department of Health.
If the lice are very persistent, boil up some Quassia chips (75p for 25g) and, after allowing to cool a little, use the warm infusion as a final rinse. It tastes very bitter, so don't get any in your mouth.
