NYDA® express’ innovative dual dimethicone solution suffocates head lice at every stage of the life cycle. Some other head lice treatments target the louse’s nervous system, however unhatched eggs haven’t developed a nervous system yet. But, head lice, larvae and eggs all need to breathe. That’s why NYDA® express uses a unique combination of silicones to deeply penetrate the airways of all lice (including eggs) to stop their breathing. This innovative suffocation technique is scientifically proven to kill head lice in 1 application* (no repeat treatment necessary) without any harsh chemical smell or burning sensation. * ÖKO-TEST.App Eltern 11/2017 ** 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.
