All lice need to breathe. That’s why NYDA® express head lice treatment uses dual dimethicones (silicone oils) to deeply penetrate the airways of eggs and adult lice and stop them from breathing.
This innovative suffocation technique is scientifically proven to kill head lice at all stages of the life cycle and stop an infestation in its tracks.
*We recommend checking hair again 8-10 days after treatment. If the treatment solution does not completely cover all hair, some eggs may not be killed and may hatch up to 7-8 days later. If any live head lice are detected, repeat treatment and check hair again in a further 8-10 days. For external use on unbroken skin only. Always read the instructions for use.

How Do Head Lice Spread?
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.

What Are Head Lice?
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.

I Can Still See Eggs Attached to The Hair, Did The Treatment Work?
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.
Who Can Use NYDA® express?
NYDA® express is suitable for all ages, including infants and pregnant women.
Always talk to your health professional before using any medicine or medical device during pregnancy.
Why Does NYDA® express Suffocate Lice and Their Eggs?
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*!
