Head lice treatment - Hedrin new revolutionary formula

Healthcare Professionals' Information

4% Dimeticone - effectiveness without restrictions

Hedrin is a novel and highly effective method of eradicating head lice which offers considerable benefits to clinicians and their patients. It is now available both as a licensed medicine and a medical device, both employing the full benefits of 4% dimeticone.

Clinical trials have demonstrated 4% dimeticone's superiority to 0.5% malathion¹ and its effectiveness in large scale tests in-vivo².

A recent experiment by Ian Burgess, Director of the Medical Entymology Centre has also demonstrated that Hedrin's mode of action is entirely a physical process³. Hedrin cannot therefore trigger resistance and can be used as often as required with no complex rotation policies.
