Deal with every phase of head lice, with Hedrin: Treatment

Hedrin® Once Liquid Gel eliminates head lice and their eggs. It is not a chemical poison, but works by physically smothering the lice. It also contains Penetrol® which helps the product to penetrate louse eggs in order to kill them. Hedrin® Once Liquid Gel has been shown to work with only one application, but a further check should be carried out one week after application to make sure that no lice or eggs have managed to escape the coating. If any live lice are discovered then the treatment can be re-applied. The gel can safely be used as often as required without lice developing resistance.
