You can buy Nyda Pump Spray as an over-the-counter medication for the treatment of head lice. Head lice are wingless insects that spend their entire life on the human scalp, feeding on your blood. They are non-disease carrying and attach their eggs to the base of scalp hair. The female secretes a glue-like substance from her reproductive organ to secure the nits. Other than a possible secondary infection from scratching your scalp where the lice have bitten you, they are harmless and are more of a cosmetic problem than a medical one.

Nyda Pump Spray contains Dimeticone, an effective silicone-based substance for treating head lice infestations. Conventional insecticides contain chemicals that poison the head lice and parents are wary about exposing their young children to these products. Nyda Pump Spray has no harmful chemicals; it can be used on children two years and up.

Dimeticone fills the breathing system of lice, nymphs, and eggs, suffocating them. Repeat applications may be required to rid the lice entirely. Read the leaflet carefully to make sure proper application is achieved. Nyda Pump Spray may cause eye or skin irritation, you should contact your doctor if these symptoms persist or worsen.
