Did you know that there are antiparasitic treatments that can act directly on the nervous system of the parasites and also eliminate the nits? When an infestation appears, choosing an effective treatment is essential to get rid of these tiny parasites and prevent their reproduction cycle from continuing.

Among the ingredients used to combat pediculosis we find: pyrethrins, natural insecticidal substances extracted from the flowers of the chrysanthemum, which have inspired the development of pediculicidal active ingredients such as D-phenothrin or fenothrine. This ingredient belongs to the pyrethroid family and stands out for its biocidal action, It is capable of altering the nervous system of the lice, causing their paralysis and subsequent death.

But eliminating adult lice is not enough. nits, Eggs that remain attached to the hair also play a fundamental role in the infestation cycle, as they can lead to the development of new parasites. Therefore, it is especially important to choose a treatment that combines pediculicidal and ovicidal action, Capable of acting on both the lice and their eggs.

This is the case of NOSAATTACK Piretrina 1 %, an antipilose treatment new generation, Formulated with D-phenothrin at 1 %%, developed for Eliminate lice and nits in just 10 minutes and that, according to the studies of its formulation, It has not generated resistance.

But how does this active ingredient work and why is its ability to combat head lice so important? We’ll tell you all about it!

What is pyrethrin and why is it used to remove lice?

The pyrethrins They are natural insecticidal compounds that are obtained from certain flowers of the genus Chrysanthemum, Especially the Dalmatian chrysanthemum. These substances are known for their insecticidal activity and have served as the basis for the development of the synthetic pyrethroids, such as D-phenothrin.

The D-phenothrin or fenothrine It is a pediculicidal active ingredient that acts directly on the nervous system of lice, interfering with their normal functioning until they are eliminated. Its mechanism of action makes it an option for combating active infestations when the presence of live lice in the hair is confirmed.

In addition to its action on lice, Pyrethrin of NOSAATTACK Piretrina 1 %, Its pediculicidal and ovicidal efficacy allows eliminate both the lice and the nits, Offering a complete treatment for the infestation. Covicidal ability means that It acts against the larvae, compromising their viability and making it difficult for them to hatch.

This characteristic is especially important because it allows for action to be taken at different stages of the parasite's life cycle.

How does D-phenothrin act on lice?

The secret of its effectiveness lies in its neurotoxic action mechanism on insects. Fleas have a nervous system that controls their movements and vital functions. To transmit nerve impulses, their cells use structures called sodium channels.

When D-phenothrin comes into contact with the parasite, it alters the functioning of these channels, prolonging their activation and causing abnormal nerve activity that ultimately results in their paralysis and death.

This action stands out for three characteristics:

  • Biocidal action: It acts directly on the nervous system of the lice, altering their vital functions until they are eliminated.
  • Pediculicidal efficacy: It allows the fight against the live lice present during an active infestation.
  • Quick action: It is used in specific treatments to combat pediculosis, such as NOSAATTACK Pyrithrine 1 %, which eliminates lice and nits in just 10 minutes.

And how does it act on the ligaments?

The Linds are the eggs that the female lice deposit and attach firmly to the hair., Usually near the scalp. A female can lay several eggs per day, and under normal conditions, these can hatch approximately between 7 and 10 days later.

This means that, even if we eliminate the adult lice, if viable eggs remain in the hair, new lice can be born and the infestation can continue.. Therefore, ovicidal action is a particularly relevant characteristic in an antipilose treatment. Treatments with ovicidal activity act on the eggs of the parasite, compromising their viability and preventing them from continuing their development until hatching.

The NOSAATTACK Pheretrine 1 formula % It is effective against lice and nits, allowing you to combat different stages of the infestation cycle in a single application.

In addition, the use of a steel ladle It facilitates the mechanical removal of lice and nits attached to the hair, completing the treatment routine.

Why is it important to choose a treatment with ovicidal action?

Because viable larvae can hatch days after application, This leads to new lice and prolongs the infestation. For this reason, choosing a treatment that acts on both the parasites and their eggs allows for addressing different stages of their life cycle.

NOSAATTACK Piretrina 1 % It is specifically developed to combat both, offering a solution with Pediculicidal and ovicidal action in just 10 minutes.

It is important to follow the application instructions, perform the subsequent revisions, and repeat the treatment only when indicated by the labeling.

The key is to differentiate between prevention and treatment: While preventive routines help with daily hair care and facilitate check-ups, pediculicidal treatments like NOSAATTACK Pyrithrine 1 % are intended to act when an infestation already exists.

Treatment from 2 years of age and recommendations from the WHO

The World Health Organization (WHO) It collects fenethrine among the insecticides used to control lice.

Pyrethroids have been used for decades in pediculicidal treatments thanks to their ability to act directly on the nervous system of insects.

Its mechanism of action allows it to combat active infestations, while its effectiveness against lice depends on the characteristics of the treatment used.

In the case of NOSAATTACK Piretrina 1 %, Its formula presents biocidal and ovicidal action, allowing the removal of both the lice and their eggs.

In addition, it is indicated for children from 2 years old, Following the instructions for use of the product.

It is important to remember that the WHO lists the use of fenhotrine in the control of pediculosis, while the minimum age, the duration of application and the conditions of use must be consulted in the labeling of each treatment.

Therefore, choosing a specific product that has been proven effective against lice and nits and using it correctly is essential to combat an infestation.
