Hedrin solution contains dimeticone, which is used in many pharmaceutical and cosmetic preparations. A 4% concentration has been found to affect the physico-physiological activity of lice. It is less effective in its ovicidal activity and therefore two applications, 7 days apart, are required. It contains no neurotoxic organophosphate insecticides and acts by a physical process that covers the lice and disrupts their ability to manage their water balance so that treated insects fail to excrete surplus water. Its activity is not diminished in insecticide-resistant head lice
