Some studies suggest that girls get head lice more often than boys, probably due to more frequent head-to-head contact. In the United States,
People with short hair were least likely to have lice, and people with thick hair more often had lice than those with thin hair. Lice also can't survive if hair is less than 6 millimetres long, which is why shaving a person's head is a very effective treatment, Rukke said.
Anyone who comes in head-to-head contact with someone who already has head lice is at greatest risk. Spread by contact with clothing (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels) used by an infested person is uncommon.
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.
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.
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.
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.
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.
Usually, you would have to be in head-to-head contact with a person who has lice. This can be common in schools or kindergartens, where children are often close together. Sharing combs, brushes, towels, hats, and other personal items can hasten the spread of head lice.
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.
Lice for Building Immunity
Recent studies have shown the benefits of having lice. While it may sound ridiculous and unbelievable, there's scientific evidence that a certain kind of louse can be beneficial in reducing the chances of developing immune deficiencies.
Anyone can get head lice, but some people are at greater risk than others. Those people include: Children between the ages of 3 and 11 years. Girls are more likely to get head lice than boys, possibly because of their play styles and sharing of personal items.
They hang around children often
Naturally, parents, teachers and other adults who spend time within close vicinity of children are more susceptible to lice infestations. To sum it up, the reason why some people do not get lice is due to pure luck.
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.
Comb dead and any remaining live lice out of the hair using a fine–toothed nit comb. If, after 8–12 hours of treatment, no dead lice are found and lice seem as active as before, the medicine may not be working.
Infestation timeline
So if you look on the scalp and see no visible adult lice and several small nits, it's likely that you've caught lice in the earlier stages and had them for less than 2 weeks. Nits and nymphs: 1.5 to 2 weeks. If you see nits and small, moving lice, you've likely had lice for 1.5 to 2 weeks.
Itching on the areas where head lice are present is the most common symptom. However, it may take up to 4 to 6 weeks after lice get on the scalp before the scalp becomes sensitive to the lice saliva and begins to itch. Most of the itching happens behind the ears or at the back of the neck.
In fact, because girls generally have longer hair, it is easier for a louse to find and climb up the hair of a female. Nonetheless, each year many boys are diagnosed with head lice. Adult men are less likely than young boys to get head lice.
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).
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.
Introduce natural predators (Ladybugs)
Ladybugs can eat 100 lice a day!
Small studies have also shown that tea tree oil in combination with lavender oil can kill lice eggs and reduce the number of live lice. Tea tree oil seems to be relatively safe for use on the skin, although it can cause irritation or swelling for some. Remember, though, that it is poisonous if swallowed.
There are two reasons for a recurrent lice infestation: The lice treatment you used didn't work. You or someone in your family came in contact with lice again.
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.
