Kill Head Lice and Their Eggs in 10 Minutes!

The dimethicones in NYDA^®  express are potentially flammable, similar to a hairspray or perfume. However, dimethicones only ignite when they come into contact with an open flame.

To prevent possible accidents, the flammability of NYDA^® express and the correct handling of the product is as follows: “Because some ingredients are flammable, NYDA^® express may not be used in the presence of an open flame or incandescent objects. Keep NYDA^® express away from heat and ignition sources and do not smoke during treatment.”

Although there is a possibility that coloured hair may change or the durability of the colour may be shortened, since NYDA® express was introduced to the market in 2006, there have been no reported problems associated with coloured hair.

As a precaution, users with coloured hair should wait two days after treatment to recolour as the main components of NYDA^® express should be washing out by then.

NYDA^® express eliminates headlice and their eggs by spreading over the scalp and deeply penetrating the airways of the lice. This effectively closes the airways and suffocates them.

Since water has a higher surface tension than NYDA^®, it is not able to penetrate the respiratory system of the headlice. If NYDA^® express is applied to wet hair, the product dilutes and this restricts successful treatment.

Head lice attach their eggs to the base of hair follicles with a strong “glue” that doesn’t dissolve with treatment, even though the embryo inside is dead.

To help remove dead eggs, comb the hair thoroughly using a fine-tooth lice comb.

NYDA® express is suitable for all ages, including infants and pregnant women.

Always talk to your health professional before using any medicine or medical device during pregnancy.

Pesticide treatments kill head lice by attacking the louse’s nervous system. However, head lice don’t develop a nervous system until they hatch.

Conversely, all head lice need to breathe.

That’s why NYDA® express uses two types of dimethicone silicones to block the airways and suffocate head lice, killing them at all stages of the life cycle (including eggs), s0 there’s no repeat treatment necessary*!
