Adults are not immune to head lice. In fact, if you have any close contact with children or even parents of children you can be at risk of catching them if they have them. Lice transfer primarily through head to head contact, so you would have to get close to the other person.
Why Do Kids Get Head Lice More than Adults? The answer is pretty straightforward. It's not that the pesky critters prefer children's blood to adult's. It's the simple fact that kids are in closer contact with one another on a daily basis.
In fact, adults can get lice anytime their hair is in close contact with the hair of someone who has lice. Whether public transportation, concerts, or crowded areas, any situation in which there is hair to hair contact puts adults at risk of getting lice.
'' Generally, children are less protective of their personal space, more likely to come into physical contact with one another, and more likely to share personal items like clothing or hairbrushes, which make it easy for the bugs to travel from person to person.
People who had medium long hair had the highest incidence of lice compared to those who had short and long hair. People with short hair were least likely to have lice, and people with thick hair more often had lice than those with thin hair.
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.
In the United States, infestation with head lice is much less common among African-Americans than among persons of other races. The head louse found most frequently in the United States may have claws that are better adapted for grasping the shape and width of some types of hair but not others.
While head lice live in your hair and feed on your scalp, body lice usually live in your clothes and bedding. They travel to your skin several times a day to feed on blood. Your clothing seams are the most common places for body lice to lay their eggs (nits).
There is no specific hair type that lice prefer. All lice need is a clean strand of hair to attach to. It doesn't matter the thickness, the length, if it's been colored, if it's straight, or if it's curly. It has been found that people with longer hair tend to report getting lice.
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.
Head lice can affect anyone but occur most often among children between the ages of 3 to 11 years old, along with their families. Children are more at risk, as they make head-to-head contact with other children when playing together and may share items that have contact with their hair.
In the middle ages, humans couldn't get away from lice. They were an unavoidable part of their life and lice didn't discriminate; they infected all parts of society from serfs to royals. People in the Middle Ages took lice to their grave as well.
Head lice most often affect children. The insects usually spread through direct transfer from the hair of one person to the hair of another. Having head lice isn't a sign of poor personal hygiene or an unclean living environment. Head lice don't carry bacterial or viral diseases.
Experts do suggest however that keeping long hair pulled up and back is a good way to ward off lice and nits. If hair is out of the way it is not as easy for someone to brush up against it and pass on a louse, or a nit to find its way on a scalp.
In order to have nits, you had to have had an adult female lay them. But it is possible to have Nits and no lice in the very early stages of an infestation.
How many head lice are usually found on an infested person? Typically, 10–15 head lice are found. The number of lice often depends on personal hygiene, for example, how often the person bathes, shampoos, or changes and washes his/her clothing.
WHICH HAIR TYPES ARE MORE LIKELY TO GET HEAD LICE? Here's the short answer: all types. Lice do not care what color or thickness your hair is, whether it has been dyed, or whether it is straight or curly.
The basics about lice
Lice are tiny insects that live in hair, bite, and can multiply quickly, laying up to 10 eggs a day. And lice don't discriminate! Anyone can get lice, regardless of age, social status, race or gender. Luckily, lice don't spread disease contrary to popular misconception, but they do itch!
7) Tying wet hair: Most of us do not realise it but the major cause of hair damage begins when you tie your wet/ semi-dry hair. Doing so can lead to major hair problems like hair loss, hair thinning and in extreme cases, baldness. In addition, it can lead to dandruff problems, lice and scalp infections.
The most likely explanation is that by the time H. sapiens evolved in Africa about 200,000 years ago we had our own lineage of head lice, and then picked up more from H. erectus on our travels, says Reed. The study is reported in the current issue of PLoS Biology1.
Genetic evidence suggests that human ancestors acquired pubic lice from gorillas approximately 3-4 million years ago. Unlike the genus Pediculus, the divergence in Pthirus does not match the age of host divergence that likely occurred 7 million years ago.
Head-to-head contact with an already infested person is the most common way to get head lice. Head-to-head contact is common during play at school, at home, and elsewhere (sports activities, playground, slumber parties, camp). Although uncommon, head lice can be spread by sharing clothing or belongings.
They don't stay living inside the dreads because there they have nothing to live on, they have no food. However, they can use the root zone a little further from the skin to lay eggs and breed (the baby louse is called a nit). Lice usually go to dense hairs where it's easier for them to find a hiding place.
Unfortunately, the much-touted 'fact' about scientists discovering 19 new types of lice in Bob Marley's dreadlocks after his death are entirely apocryphal. One did sell for £2,500, though. Marley, whose Rastafarian faith dictated he shouldn't ever cut his hair, was well known for the perfect shape of his dreads.
Parasites such as lice have a role in the conditioning of a 'natural' immune system and reducing the likelihood of immune dysfunctions, a study of mice from a Nottinghamshire forest indicates.
