The bad news in advance: unfortunately no. Head lice have been faithful to humans for millions of years - an extinction is unlikely. But there is also good news: the little creepy-crawlies are absolutely harmless. They are annoying, but transmit no diseases in our latitudes. This raises the question of how head lice can be eradicated as effectively as possible on your own head - perhaps with better hygiene?

The head louse - a little survival artist

The human head louse (Pediculus humanus capitis) is fully grown no larger than a sesame seed. It will be up to three millimeters long. Her six legs are equipped with claws that hold her very effectively - preferably in the region of the hairline. There, the louse attaches their about one millimeter long eggs, which are also called Nissen. Contrary to popular belief, the animals do not jump or fly, they crawl. To change their host, head lice need direct hair-to-hair contact - without them, they could actually eradicate. In order to spread it, people literally have to put their heads together. This happens again often in children. Lice thus have a particularly easy time in day-care centers and schools.

On textiles, such as clothing or bedding, they survive only briefly because lice need blood as food. Without a host they starve or dry up after one to two days. So as long as there are humans, head lice probably will not be eradicated in the future. So we'll have to deal with the parasites even longer. But there are tips to protect yourself from lice.

Head lice and hygiene - how is that related?

In many minds stubbornly persists the conviction that especially those head lice get whose hygiene leaves much to be desired. But that is not the case. For the hair care of their host, the head lice are not interested at all. It does not matter if someone washes their hair daily or once a week. Head lice can therefore not be eliminated with improved hygiene.

However, a certain cleanliness plays an important role for those who want to get rid of the small animals again. As soon as it is clear that children and possibly even their closest contacts are affected, the right course of action is crucial. The Lice and Nissen comb not only helps to detect infestation by scrutinizing individual strands of hair, it also aids in the removal of the animals and the eggs stuck to the scalp. A regular, thorough training (Str hne Str hne) is part of any successful L usetherapie. display

In addition, the use of a (gentle for humans) gentle L usemittels helpful, the L use and Nissen abt tet by oxygen deprivation successfully. Affected people use the remedy at the beginning of therapy and again after about nine days. Nits hatch after eight to ten days, so a second treatment after that time is for safety. It is not supposed to survive a single egg.

In addition to the treatment of the head, it is recommended that the textiles. Clothes and bedding are, if possible, washed at 60 degrees. If you do not tolerate this temperature, place in a plastic bag for at least a few hours in the freezer after which it is free from lice. So head lice if they have already set thanks to good hygiene in the end but no more chance.

Important: If one or more children are affected in a facility, open-mindedness is crucial. The head lice can at least be eliminated without problems, if all parents are informed, their children are examined closely and act accordingly in case of an infestation.
