How Does NYDA® express Eliminate Lice and Eggs?

All lice need to breathe. That’s why NYDA® express uses dual dimethicones (silicone oils) to deeply penetrate the airways of eggs, larvae and adults 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 only. Always read the instructions for use.
