Product description

With this clinically proven Hedrin liquid gel you can deal with head lice at any stage in 15 minutes

Hedrin once liquid gel kills lice and their eggs. It is not a chemical toxin, but instead physically suffocates the lice. It also contains penetrol, which aids in penetrating louse eggs and killing them. Hedrin once liquid gel has been shown to function with just one application, however a follow-up inspection one week later should be performed to ensure that no lice or eggs have escaped the coating. If any live lice are found, the treatment can be reapplied. The gel can be applied as often as needed without causing lice to develop resistance
