Each parent, combing the hair of his child from lice, experienced an irresistible temptation to grab an electric brow and end this. But is the loss of all hair really can save the world from lice? In a new study, scientists gave an answer to this question, writes iflscience.

Theoretically, the absence of hair could really solve the problem of lice, since these parasites live on our hair and are specially adapted to this habitat and are simply not able to survive in the wool of other animals. Thus, if people did not have hair, these parasites simply would have nowhere to live.

However, in practice, this, alas, would be quite difficult to achieve - not least because people would have to remove hair throughout the body for this. Science knows that people carry three different ectoparasites:.

As follows from the names, each of these species occupies a certain territory: for example, pubic lice I feel comfortable among dense and bristle hair in the lower part of the human body, but they can hardly cling to the hair on the head.

Several studies also suggested that lice infection can decrease around the world, since the removal of pubic hair is becoming increasingly common. For example, in the 2006 article, scientists hinted that lice may not remain on Earth if the Brazilian depilation becomes more and more widespread.

In another study in 2014, scientists have found that pubic lice is now much more common in men than in women. Such statistics correlate with the growing popularity of Brazilian depilation among women.

All these results hint that lice can really disappear from the face of the earth if people will remove all hair. However, such a decision suggests that humanity will have to do this at the same time and support the " For safety, we will also have to wash all the hats in the world and, possibly, all our clothes, as they can also contain nits. And pillowcases too, if we are really seriously configured.

If we assume that people will once go to this step, the plan can really potentially save the world from lice. However, such experiments have never been conducted, and therefore it is difficult for scientists to predict whether he will work.

For example, even if all ectoparasites are destroyed, scientists suspect that other species will probably be able to fill this gap when the hair on people's bodies grow again. In the end, we know that human head and paid lice descended from similar chimpanzees parasites, and the pubic lice descended from gorillas, whose fur is beautiful and in the texture resembles pubic hair.
