Head lice treatment - Hedrin new revolutionary formula

About Hedrin Once, containing 4% dimeticone


Hedrin treated louse suffers gut rupture

Hedrin is specifically formulated to kill head lice without the resistance which can sometimes be associated with traditional insecticides, which act by poisoning the louse.

Its revolutionary formulation is based on Dimeticone, which acts as a physical inhibitor by smothering the louse, preventing its ability to excrete surplus water. One of the largest clinical studies ever conducted on head lice has proven that Hedrin is an effective method of lice eradication.1

Hedrin really works on real children

A clinical trial conducted on 36 children in Turkey in April and May 2008 demonstrated that Hedrin has 97% effectiveness.2

To minimize the opportunites for re-infestation, the trial was conducted in an isolated community.

Hedrin is an odourless, colourless formulation which does not contain pesticides. Because it is not absorbed through the skin, it is suitable for use on children as young as six months. Hedrin does not contain any solvents which could be problematic to people with asthma.1

Hedrin Once contains Dimeticone which is proven to be well tolerated, and already widely used in the manufacture of cosmetics and toiletries.


In countries all over the world, head lice have become resistant to many existing treatments which may result in infestations within schools and communities taking longer to eradicate.3,4

However, because Hedrin works in a purely physical way, resistance is not a factor and efficacy is not diminished even in lice resistant to other treatments.

There is no need to try different treatments for head lice because Hedrin can be used again and again.
