Hedrin 4% Spray is a convenient and easy to use treatment for head lice. The active ingredient dimethicone works by suffocating and dehydrating the lice, and penetrates their eggs to tackle the infestation at its root.
Since the effect is physical rather than chemical, lice cannot develop resistance to it, providing effective treatment for lice without the need for insecticides or poisons.
This treatment requires just two overnight applications spaced 7 days apart, and is available to order without prescription.
