Using a patented formulation which acts as a physical inhibitor, Hedrin is effective against pesticide-resistant lice.
Hedrin's active ingredient, 4% dimeticone, penetrates the lice spiracles and into the trachea (tiny passages for air and water vapour). It also coats the lice, causing them to become permanently immobile.
Blocking the spiracles stops the lice getting rid of excess water - which can cause their guts to rupture if they have fed recently.
Even if the lice don't rupture their guts, Hedrin makes them immobile, causing them to starve to death.
Because Hedrin kills lice without insecticides, you can use it as often as you like without any danger of the lice becoming resistant. And Hedrin does not contain any solvents that might
cause problems with asthma sufferers.
A clinical trial conducted on 36 children in Turkey in April and May 2008 demonstrated that Hedrin has 97% effectiveness.¹
To minimize the opportunites for re-infestation the trial was conducted in an isolated community.
