Pediculosis is the infestation (do not confuse the ‘infest with ‘infect’) of lice or nits which are usually produced in the head.

The infestation causes irritation and itchiness of the scalp, particularly at the nape of the neck and above ears.

Contagion is produced directly, person to person.

Therefore, schools, nurseries or summer camps are places where children easily become infested.

Pediculosis may also affect other parts of the body.


Some parents feel ashamed when the school informs them that their children have lice. It should be made that having lice does not necessarily means a lack hygiene. Some hair which is well cared for may be infested and in turn, transmit it to others.

Children borrow and share toys, hats, scarves, clothes, hair bands; they also paly together, hugging and cuddling each other.

Therefore, there are many situations which encourage contagion.


Children with lice and nits, which they should not be confused with dandruff, must not go to school while they are undergoing the appropriate treatment.

Curing of pediculosis has two phases: one against the lice and another against nits.

The pediculicide shampoo and lotions kill the lice, but they do not always kill the nits, which must be removed by hand.


Hair washing will be carried out using a suitable shampoo, rubbing the entire scalp carefully, particularly the nape of the neck and the area around the ears.

The shampoo must be left to act for around fifteen minutes before rinsing the hair with lots of clean water. This may be repeated several times.

To prevent lice infestation, it is particularly advisable for school-aged children to periodically use some of the lotions(colognes) which are sold in the pharmacies.

We advise that those which contain DDT should be avoided.

As regards the instructions for their use, the reader should refer to the corresponding manufacturer’s inserts.
