Do lice prefer certain people or blood types? Lice prefer certain blood types. O+ being the most desired. Once feeding on one blood type, they will die if a different blood type is introduced.
Although head lice can feed on different blood types, they cannot thrive on different Rh blood factors. Therefore, lice will only prefer to move to somebody else of the same rhesus factor irrespective of the blood type.
If lice from the head of an individual with a lice infestation with the blood type A positive (Rh +) transfers to the head of another individual whose type of blood is B negative or O negative (Rh -), they cannot survive.
Although parents and teachers may feel like some children are more attractive to lice than others, there is no research evidence that suggests that head lice prefer one person over the other, Rukke, who is a researcher at the NIPH Pest Control Department, said.
Unsurprisingly, hair color proved to be the least important factor when it comes to head lice, but hair texture did play a role. He found that students with straight hair had the least number of lice, followed by students with curls, and the students with the highest amount of headlice cases were students with waves.
A person gets head lice because the insects crawl from person to person by direct contact or by sharing items — including combs, brushes and hats — with another person who has head lice. Poor hygiene doesn't cause head lice.
Head lice seem to be more common in Caucasian, Hispanic, and Asian American people than in African American people. For example, fewer than 0.5% of African American schoolchildren experience head lice compared with about 10% of schoolchildren of other races.
Who is at risk for getting head lice? Head lice are found worldwide. In the United States, infestation with head lice is most common among pre-school children attending child care, elementary schoolchildren, and the household members of infested children.
Head lice do not care about the blood type someone has, it is the Rh factor of the host that will determine if the infestation will thrive or not. Transferring from blood type to blood type does not affect their infestation but going from a negative to a positive host will play a role.
As far as we know, there have not been any clinical studies proving any human population to be immune to head lice. However, head lice can have difficultly attaching their eggs to hair that is thick or coarse; therefore, those individuals may be less likely to experience head lice infestation.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits.
Head lice reproduce sexually, and copulation is necessary for the female to produce fertile eggs.
Anyone can get head lice. They are not a sign of being dirty. Most people don't know they are infested until they see the nits or lice. They are found throughout the world, most commonly on children.
Lice don't care if hair has been colored. As long as a louse can grab on to a hair strand, it can make its way to the head where its food supply (blood) is. Myth #6: Lice like dirty hair.
Pubic lice are super common.
Millions of people get infected with pubic lice every year. They are tiny insects that look like tiny versions of the crabs you see at the beach.
Body lice infestations (pediculosis) are spread most commonly by close person-to-person contact but are generally limited to persons who live under conditions of crowding and poor hygiene (for example, the homeless, refugees, etc.).
A preventative shampoo and spray can break the life cycle. A shampoo that kills lice before they can lay eggs is critical for closing the “bridge” from one head to another.
Getting Lice While Bald
They find it difficult to feed and quickly die off. Lice may attempt to attach, but the environment is unsuitable for their survival. While bald people may become temporarily affected by head lice they often leave for a better suited host or die off. Thin or sporadic hair can still attract lice.
Blue is the second most common eye color globally, with an estimated 8 to 10 % of people having blue eyes. A majority of these people are of European descent, however, Black people can be born with blue eyes even though it's pretty rare.
Coconut, tea tree oil, lavender, eucalyptus, rosemary, lemon grass, and peppermint are scents popularly believed to repel lice. Using any coconut scented shampoo and conditioner is an easy way to increase your defense. At 1% concentration, tea tree oil killed 100% of head lice after 30 minutes.
Introduce natural predators (Ladybugs)
Ladybugs can eat 100 lice a day! Plant lice, anyway, but I'm sure it's the same with head lice. COVER YOUR CHILD IN LADYBUGS. You can purchase them at any of those “Brew 'n Grow” type stores where people grow weed by equipment and pretend to grow tomatoes with it.
Hairspray makes it harder for the louse to grab hold. The smell of hairspray and the use of solvents (sad but true) in them can also deter creepy crawlies from finding their way in. Not to mention that if you're tying longer hair back, you've got a double whammy.
