Dealing with a Head Lice Infestation
The problems with head lice are many and one of the main ones is the speed at which they spread. It is a common misconception that head lice fly – they are, in fact, wingless – but they can only move between hosts by walking from hair to hair; this is why they spread very fast among young children – think of the playground and the physical contact.
It is also a myth that a head lice infestation can only occur where the child suffers from less than satisfactory hygiene; a head louse is not choosy about who it lives on, and all it seeks is head from which it can feed upon its staple diet – our blood.
Head lice multiply at an alarming rate: the female adult louse lays up to eight eggs – the famous nits – every day of her thirty day life, and a quick calculation gives you easily over 200 eggs. Each nit stays attached to a hair follicle for approximately one week then hatches as a nymph or young louse. In just a week to two weeks time it becomes a breeding adult, and begins the cycle once more. From that description it is simple to see just how quickly an infestation can spread, and how important it is that it is treated correctly.
Treating head lice is a subject that raises many arguments: there are many insecticide lotions – using Malathion, Permethrin or Lindane in the main – that are available by prescription, and these are widely proven to be successful in many cases, and there are natural shampoos such as those including Tea Tree oil, and essential oil that is used in many herbal medicines, and the choice is a very personal one that is left to the individual.
There also exist some more unusual ways of tackling head lice and nits – including the odd practice of smothering the hair, and the lice, in mayonnaise – that are known to be successful if somewhat messy, and the tried and tested head lice comb is an essential tool in all of this, whether in traditional close toothed form or in the shape of the new style of electric combs that shock the lice to death.
What is important to understand is that the first treatment will almost certainly not rid the head completely of nits, and the patient will need to be closely observed over the next two weeks in order that any emerging head lice nymphs are caught before they can begin to breed.
