Head Lice Pictures
Head Lice Pictures – Essential and Amazing
The identification of head lice has been enhanced in terms of ease of late by the ability to take photographs of these miniature creatures using advanced photographic technology. Using a microscope attachment enables the photographer to get a much magnified picture of the louse, one that shows incredible detail and makes recognizing lice much easier.
Pick up any antiquated scientific journal or book covering the subject, however, and you will still see head lice pictures, often very intricate and highly detailed colored plates that are, in fact, quite beautiful and clearly have taken much time to create. How these were done is a question often asked.
A talented artist would be needed to create such images, and he or she would be using a microscope or magnifying glass to look at the creature; consider how much time and effort was needed to create such an image back then – a hundred years ago or more – and how easy it is to take a photograph and manipulate it to our requirements using affordable everyday computer systems, and the difference in dedication becomes clear.
Furthermore, modern printing techniques have enabled the production of high resolution images, with detail far beyond that that could have been imagined by our artist of old.
Technology has clearly played a great part in allowing us to produce images that show such intricacies as the head lice life cycle, and in terms of diagnosis such material is essential to us now; head lice prevention can be very much aided by understanding what the creatures look like and how the evolve, hence a series of photographs showing the evolution of the head lice, from nit to adult, can be of great interest to a sufferer or one who suspects an outbreak.
Advances in technology in the photographic world have opened our eyes to a mass of miniature things and creatures that were previously unseen; consider that an adult head louse is no bigger than a pin head, and you see the immediate benefit of being able to photograph such creatures and enlarge the image, without loss of detail, on a computer. Furthermore, advances in video technology have allowed us to film lice on the move, something that has taught us a great deal about how they spread.
Having lice pictures available is something that the medical profession has found very useful indeed, and while we can only marvel at the wonderful pictures drawn by scholars of old, we must not forget the skill involved in photographing tiny creatures.
Permethrin head lice
About Permethrin head lice treatments
There is much debate in the medical profession as to the best method to deal with the head lice problem; many people adhere to the belief that the best way is to use insecticide based lotions and shampoos – and there are many on the market – while others insist upon the more friendly and less chemically enhanced methods that are naturally based. The jury is still very much out, but is worth us looking at one of the insecticide treatments as a guide, and for this purpose we have chosen the Permethrin head lice treatment.
First and foremost, it is worthwhile remembering that permethrin, like all insecticides, is a poison, and that while it is only present in very small amounts in the products you can buy over the counter many people are concerned about applying such substances to the heads of their children; although this is understandable, the manufacturers and suppliers insist that the substance is safe if used carefully, and that it is successful in treating the head louse problem.
However, there is some opposition to that in the form of research in Great Britain, which concluded that permethrin is of ‘limited use’ in controlling head lice, but alternative views, as usual, abound.
Nevertheless, for many permethrin remains the number one treatment for head lice, and when itchy head lice strike you need to know you have the arms to turn to. It is available in two forms with brand names Nix and Elemite; the first is a 1% solution, the second a stronger five percent version, and while the former is an over the counter product the latter is obtainable only by prescription.
It works by being applied as a cream which is then rinsed off, and unlike many such applications it leaves behind a substance that is specifically aimed at killing nymphs, these being the emerging young lice that hatch from nits after a week. This is important as the nits are notably hard to remove, and even if a combing regime has rid the hair or live lice, there will be nits waiting to hatch over the next few days.
Argument persists as to whether the insecticide treatments are more, or less, effective that equivalent natural ones; some say that a shampoo equipped with tea tree oil is equally, of not more, effective while being natural, but the fact remains that many have to try different solutions to the head lice problem before finding a solution, and permethrin may be that solution.
All about the Head Louse
Every one of us has heard of head lice, and many of us will have endured the unfortunate passage of suffering from itchy head lice, but what do you really know about them? Head lice are actually fascinating creatures that, although unpleasant and irritating, are quite harmless; they do not present any life threatening qualities, and they do not – contrary to popular belief – signify that the host is hygienically challenged, they simply happen to enjoy living on our hair, feeding on our blood and laying their eggs, nits, on our scalp!
What does a head louse look like? If you run a quick internet search for head lice pictures you will be presented with a variety of depictions of these miniature mites; one thing you will notice is that they do not have wings, and that puts to bed the common misconception that they spread by flight. In fact, they can only do so by walking, hence they are easily spread among children who enjoy a much freer form of physical contact than adults.
It is common, also, to mistake the head louse and the head lice nit for the same thing; nit is the name given to the eggs, perhaps the most troublesome part of the equation as they are difficult to remove. This is because of a combination of factors, in the main their absolutely miniscule size and the fact that they are attached to the hair by remarkably strong natural glue. For the record, nits remain as such for up to a week, after which time they hatch into nymphs, or young head lice, and it only takes one further week for these absolutely minute creatures to grow into breeding adults.
The life cycle is completed by the adult, the female of which will live for up to thirty days in adulthood, and on each of those days will lay somewhere between six and eight nits. These itchy head lice become more, therefore, and as the symptoms can take weeks to occur, and the tiny creatures are often mistaken for dandruff, the head louse population can become rampant in a matter of a few weeks.
Interestingly, the creature breathes through two holes in the side of its body, and this is why the seemingly bizarre ritual of applying mayonnaise or olive oil to the head is actually quite a successful routine: it smothers the lice, hence ridding the host of an irritating companion.
