Head lice are small insect creatures that live on the scalp of human heads. They live by feeding off the blood from the scalp. Lice will normally feed 2-3 times a day and can be found at the base of the hair follicle and normally latch onto the hair strands. The head lice appears as a greyish brown colour and depending on their maturity the largest louse are normally the size of a sesame seed.

Clinically proven to kill head lice and their eggs in 15 minutes. Head lice cannot build up resistance against Hedrin products. Hedrin products have a physical mode of action, and instead of poisoning the louse, they work by coating it and disrupting its ability to manage water causing it to die. Hedrin is a non-pesticide treatment. This means lice are unlikely to develop resistance.

Hedrin has been clinically tested to kill lice and eggs in one go. If you are using Hedrin in order to ensure that the lice are effectively eradicated, a second dose lotion should be applied seven days after the first treatment to deal with any eggs which may have hatched since the first application. The empty egg cases are glued to the hair but are completely harmless.
