Kill Head Lice and Their Eggs

Head lice are most often spread by head-to-head contact, which is the main reason outbreaks are so common among school-aged children.

Some people think that hair accessories can also spread head lice but this is unlikely as a louse will not leave the human host unless moving to another scalp.

Head lice are tiny insects that live on the human scalp and have evolved so that they can only survive on our heads. Because they feed on the blood from the scalp, some people report an itching sensation when they have lice.

Head lice attach their eggs to the base of hair follicles with a strong “glue” that doesn’t dissolve with treatment, even though the embryo inside is dead.

To help remove dead eggs, comb the hair thoroughly using a fine-tooth lice comb.

Pesticide treatments kill head lice by attacking the louse’s nervous system. However, head lice don’t develop a nervous system until they hatch.

Conversely, all head lice need to breathe.

That’s why NYDA® express uses two types of dimethicone silicones to block the airways and suffocate head lice, killing them at all stages of the life cycle (including eggs), s0 there’s no repeat treatment necessary*!
