I think the use of the Internet has really helped in the fight against head lice. Without the Internet, I wouldn’t have access to research and you wouldn’t be reading this blog. That said, I find it sad that while we have new ways to share information, most head lice “experts” are offering up old information about how to deal with head lice. There are some head lice myths that most head lice authorities debunk, such as the myth that head lice can jump (they can’t) or that lice prefer clean hair (they don’t care about your hair, they just want your blood). But there are other head lice myths that are still promoted as fact by most websites and health authorities. Before I talk about them, I ask you, dear reader, to put away your assumptions about head lice; those strongly held believes about bugs or those compulsions that cause you to want to panic. The information I want to share will challenge so much of what you have been told about head lice. Have an open mind and read the research for yourself.
Common Sense Myth #1: To get rid of head lice, you must really clean your house and launder (or store away) your clothes, pillows, stuffed toys, and bedding.
Radical Research: Head lice are not a virus that infests your home or belongings. A louse is a bug that lives on the human head. Research has shown that extensive house cleaning or laundering makes no difference in the fight against head lice.

Common Sense Myth #2: You can get head lice by sharing the hat, brush, seat, or shirt of someone who has head lice and must take great care not to share or touch these items if they have been in contact with someone who has head lice.
Radical Research: Head lice are passed by direct head to head contact. Period. There is no real basis in the common notion that lice are transferred through inanimate objects.
Why I want you to know this: I know that this information goes against what we feel is common sense. This information was even hard for me to swallow – when I first started my journey into head lice removal, I always shared the conventional wisdom that said head lice could be transferred via our hats, brushes, etc. But the research is sound and shows us that time is wasted when we focus on trying to prevent the spread of head lice by controlling our belongings. If we spent less time trying to keep our kid’s jackets from touching other kid’s jackets in school and spent more time just checking for lice on the heads of our children, we would be so much further ahead in the fight.

Common Sense Myth #3: You need to kill the head lice through the use of a pesticidal lice treatment, such as a product containing permethrin, in order to stop the infestation cycle.
Radical Research: Numerous studies have shown that head lice have become resistant to pesticides and are simply not as effective as they once were.
Why I want you to know this: In Edmonton, our health authority and school boards are still telling parents that these pesticidal treatments are the #1 way to deal with the problem of head lice. And yet, ALL of my business comes from people who have first used these treatments. These treatments are costly and rarely work. By putting our faith in these treatments, we are preventing ourselves from actually dealing with the problem. Well meaning, conscientious people, people who have diligently followed the advice of health professionals, are going out in public, assuming that they have solved their head lice problem when they may still be infested and at risk of passing on these parasites. The cycle continues and the problem grows.

Common Sense Myth#4: That chemicals are our only weapon in the fight against head lice.
Radical Research: Wet combing techniques and the use of hot air have been proven effective in the detection and treatment of head lice.
Why I want you to know this: Mechanical removal of head lice is a very accessible and effective technique in the fight against head lice. A proper lice comb is inexpensive in comparison to the cost of lice "shampoos" and can be used repeatedly with each family member. A warm air treatment that has a great success rate in drying out eggs and a substantial success rate in drying out bugs can be carried out with a low-cost hand held hair dryer.

Common Sense Myth #5: Health and school professionals know all about head lice.
Radical Research: Health / school professionals often misdiagnose head lice and recommend unnecessary treatment or call for the removal of children from schools though active cases of head lice may not be present.
Why I want you to know this: Many school boards and childcare centres have "no-nit policies" and yet may be misdiagnosing cases of head lice. Public health and school nurses usually recommend, and some even dictate, the use of chemical treatments. However, they may not know about the most up-to-date research. You can become the expert about your child's head lice. You can detect an active case of head lice through wet combing and with regular follow up, you can deal with this problem without costly treatments. You also have a right to expect your healthy child to stay in or return to school.

Conclusion: For every new study that debunks our old myths, many more new web pages come up that reinforce the incorrect stereotypes of having head lice and how to treat it. In fact, there's research about that too. Click here. If you would like to chat about what you've read, leave a comment or email me. Let's stay informed.
