What is Head Lice?
If you are searching for 'what is head lice?' hopefully the below will detail everything you need to know. If not, please navigate back to our homepage where there is a lot more information! 'Head lice' refers to more than one 'head louse' (or Pediculus humanus capitis as they are scientifically classified). They are also commonly described as 'nits'. Nits are tiny, wingless ectoparasites that live and feed on the human head. Similarly to fleas, they bite the skin and draw blood to survive. Head lice are one of over 3000 species of louse (Order: Phthiraptera) and fall into the Anoplura Suborder (sucking lice). The head louse has a three stage life cycle, all of which take place on the human head, it is a worldwide problem (mainly in children) and unlike the body/pubic louse, it does not carry infectious diseases.

What color is Head Lice?
You may have heard people in the past say that head lice only infest dirty hair or those who are unhygienic? Well, we can confirm that they will infect any human head, clean or dirty as they are looking for a blood meal and then to multiply, so nobody is safe! Below we look at how you can catch head lice, how you can get rid of them and how you can prevent head lice, but firstly, to begin answering 'what is head lice' we could start by looking at their body. Head lice have no wings, so they cannot fly, they cannot jump or hop, they have special mouths designed for sucking blood, they have six legs with claws for clinging to their host, they range in size from 1-2mm and range in color from whitish grey to dark reddish brown. Please take a look at our Image of Lice page for a better understanding.

What is the life cycle of Head Lice?
Female adult head lice feed, mate and then lay their eggs. The eggs are attached to the base of hair shafts with sticky saliva/glue (saliva so sticky that everyday shampoos will not wash them off). Their eggs are positioned as close to the scalp as possible in cooler climates as this is the ideal environment for them to develop (warm and protected). However, in hotter climates around the world, you can find eggs placed inches away from the scalp proving that the temperature plays a very important part of the cycle. The head lice eggs will hatch into Nymphs (miniature versions of adults) who then go through further moulting before reaching adulthood. Therefore when checking for nits, you should be looking for eggs (also referred to as 'nits'), nymphs and adults. Live adult head lice confirm an infestation and need for treatment.

Head lice are caught via close head-to-head contact with someone already infested and sometimes via the sharing of combs, brushes, towels, pillows, hats and scarves. School children who spend all day together in close proximities are therefore most at risk of becoming infected and spreading head lice (usually 3-12 year olds). Sharing time on school buses, in classrooms, after-school clubs and sports teams all encourage close head to head contact and this is when head lice could craw onto fresh heads. For the rest of the family or friends, head lice can then be brought into the home and spread through similar means (brushes, etc). Many outbreaks and epidemics are often started as people do not know they have head lice. Some people have little or no signs so they go on as if nothing's wrong - however, others may have light to severe skin irritation, red bumps and white specs in the hair (similar to dandruff).

To prevent head lice, close head-to-head contact and sharing of brushes, hats, etc should be avoided (certainly by your children). Regular washing and hygiene may not 100% prevent lice, but it will help keep the chances down and also allow any lice to spotted earlier. Performing regular checks of the hair, using a nit comb, may also reduce the risk of major outbreaks in schools and communities. There were times when the school nurse would call every child in for a check-up; however this seems to have disappeared in latter years as it did nothing to prevent the issue.

Educating the young and old so they do not expose themselves to the risk of head lice will help stop major outbreaks.
