Product Information

What is NYDA head Lice Treatment?

NYDA pump spray is a medical device that contains 92% dimeticone as its main ingredient. Dimeticone is a silicone-based substance. It is used to treat head lice infestations.

NYDA works in a different way to conventional insecticides for head lice. Instead of poisoning the parasites by chemical means, the dimeticone in NYDA pump spray works by physically coating and smothering the lice. The dimeticone fills the breathing system of the lice, including the nymphs and eggs, and this suffocates and kills them. Head lice cannot become resistant to NYDA because it works in this physical way.

Who can use NYDA Head Lice treatment?

Suitable for individuals aged 2 years and above

How to use NYDA Head Lice treatment?

NYDA should be applied to dry hair. Spray the product carefully over all the hair, then massage the solution in well until the hair is completely wetted. The amount of NYDA needed depends on the thickness and length of the hair. Leave the hair for at least 30 minutes then comb carefully with the lice comb to remove the suffocated lice. The solution should then be left in the hair for at least eight hours (eg overnight) to make sure any lice and eggs remaining in the hair are killed. You can wash the solution out after at least eight hours using your normal shampoo.

All family members with head lice should be treated on the same day to avoid re-infestation.

After eight to ten days you should check that the treatment has been successful. (Any eggs that survived the treatment will have hatched by this time.) If necessary, the treatment can be repeated straight away, as described above.
