Hedrin Once Liquid Gel a colourless liquid which is highly effective against head lice and eggs. In some cases head lice have become resistant to many existing treatments which may result in infestations within schools and communities taking longer to eradicate. However, because Hedrin works in a purely physical way, resistance is not a factor and efficacy is not diminished.
Hedrin contains the active ingredient Dimeticone, which kills the head lice in a innovative way. Instead of using conventional insecticides Hedrin's active ingredient encapsulates the lice and prevents them from functioning. Another bonus with using Dimeticone is that the lice do not build up a resistance to it. This new formula also contains Penetrol which penetrates the lice eggs in order to kill them more effectively.

If a member of the family or a friend has live head lice, check all the other family members and friends and treat all other cases of live head lice which are discovered at the same time. If a friend or family member has lice without knowing, it is likely they will be passed around again and again so contact tracing is very important.
