It is important to know some basic facts about head lice in order to react without panic and take effective measures to fight these parasites.
Here are 8 common myths and the corresponding head lice facts.
Myth nº1: Head lice is a result of a poor hygiene and can be eliminated with soap and water.
Fact: This myth is still deeply rooted in our society but it is really a myth. Head lice are resistant to water and soap. Having head lice is not a question of hygiene. They can infect anyone, whatever their background or personal hygiene.

Myth nº4: Lice live in carpets, beds, clothes and couches.

Myth nº5: It is necessary to clean the house because I can catch lice through belongings and home furnishings.
