NYDA® express uses a unique combination of dimethicones to suffocate head lice and their eggs.
Some traditional head lice treatments target the nervous system of the louse, but unhatched eggs haven't developed a nervous system yet.
However, head lice at every stage of the life cycle need to breathe.
That’s why NYDA® express uses an innovative dual dimethicone formula to deeply penetrate the airways of eggs and adult lice to stop them from breathing.
This unique suffocation method has been scientifically proven to kill head lice in 1 application* (no repeat treatment necessary) without any burning or harsh chemical smell.

** 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.
