Myths and truths about head lice, vampires

Are there children more likely than others to catch ‘pee’? Are they really going to dirty hair? Does vinegar work to kill them? These little insects, which actually neither jump nor fly, they pass very easily from one head to another and as quickly as they spread among the students in a class, rumors have spread about them.

Not only children get lice, but adults too, and many times it is their own children who pass them on. However, it is true that minors are more likely to be infected with pediculosis due to the potential of hydrogen and the degree of alkalinity of their scalp. The more alkaline and sweet the PH of the skin, the more easily these insects will reproduce.

This has nothing to do with whether the hair is clean or dirty. A common belief is that lice go to oily hair, although in reality, no more than to freshly washed hair. The sebum from the scalp helps them to cling better to the hair and to leave their nits on the head, while they slip when there is no grease.

They have always been thought of as jumping insects, although in reality they do not jump from one head to another, but rather need contact. The most common way of transmitting them is by sharing combs, brushes or headbands, so when they are of school age, they must be taught to do not share their hair ties or hats with his partners.

Another widespread false myth is that lice are becoming more and more resistant to pesticide productsHowever, in more than half of the cases in which specific liquids do not seem to work, it is actually due to incorrect use of them. Permethrin, lindane or silicones such as dimethicone or cyclomethicone are some of the chemicals that kill these insects and are found in shampoos or liquid antipediculicides.

Although there are multiple anti-lice products on the market, there are also some in the home pantry, many times without knowing it. As a complement to the elimination treatment, a treatment with vinegar is carried out, which although it does not kill them, it does make them detach from the hair more easily when passing the nit comb.

Essential oils are also helpful in fighting head lice. The most common are lavender, eucalyptus, tea tree extract or pure coconut oil. However, the latter presents some risks, especially in very sensitive skin and in very young children, due to the presence of trepenes in its composition.


Not only are lice shampoos or lotions enough to eliminate them, but it is necessary to remove them from the head in case any nits have survived. The most common nit is the one with metal spikes. or plastic, but more recently some that work electronically have also come onto the market.

In no case can the products to eliminate them be used to repel them. This is how the resistance of the species to products designed to kill lice is promoted. Applying a little water mixed with apple cider vinegar in a diffuser or a few drops of tea tree oil seems much more effective so that the louse does not want to go near that head.

There is no better prevention for this head plague than vigilance, not sharing accessories or combs, because in many cases the most common symptom of pediculosis infection, itching, does not become apparent until four or six weeks later. This is the time it takes for the scalp to become sensitive to the insect’s saliva, which is what causes the itching, which also gives a female time to lay between 6 and 10 nits per day. But once they have lost their hair, they can only survive 24 hours, since without blood nourishment, they die.
