NYDA express is designed to kill head lice and their eggs using a physical mode of action rather than chemical insecticide (knock down). NYDA® express contains two dimethicones (silicone oils), which seep into the breathing holes of lice and eggs, blocks their oxygen supply which rapidly suffocates and kills them. This physical mode of action means that even head lice and eggs which have built up a resistance to chemical treatments (knockdown resistance) are still eliminated.
- Using silicone oils means NYDA® express does not have the harsh, unpleasant chemical odours of some insecticide-based head lice treatments.
- NYDA® express has been shown to be well tolerated by all ages including pregnant women and infants.
How to use:
- Apply to dry hair. Spray thoroughly over all of the hair and scalp beginning at the roots.
- Massage in well until the hair is completely saturated with the solution and allow it to sit in the hair and work for 10 minutes.
- Comb hair carefully afterwards using the comb provided to remove the suffocated lice and eggs.
- Wash out with your normal shampoo
