Nyda Express Against Lice And Nits Pump spray is used for the physical treatment of scalp hair in case of infestation with head lice (pediculosis captis). The effect is achieved by physical means � with the help of two silicone oils (so-called dimeticones) that penetrate into the breathing system of the head lice and all their developmental stages (such as nits and larvae). The pediculicide condenses and closes the breathing system of the insect. The basis of life is eliminated and lice and nits die. If used as instructed NYDA express is also effective against nymphs and eggs (nits). NYDA express must not be used in cases of known hypersensitivity to any of its ingredients. For external use only.
