Lice (Pediculus humanus capitis) are ectoparasitic insects in humans that feed on fresh blood. The itchy sensation on the scalp is caused by the saliva of the parasitic insect, introduced into the skin when it bites the scalp. The female lice lay and stick the eggs (nits) along the hairs, through a substance that in contact with atmospheric air hardens becoming a strong and waterproof fixative. Pediculosis is transmitted from affected to healthy people only through direct contact. This parasitosis is not transmitted from animals, the disease being known only to humans.***Contraindications: Nyda® express should not be used in people with known hypersensitivity to any of its ingredients.
