Hedrin contains dimethicone. When Hedrin is applied to the hair the lice become covered in dimethicone which coats their bodies and blocks their breathing holes. The dimethicone also penetrates the louses body and prevents them from being able to excrete water leading to death of the louse.
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.
Step 1
Use a comb made for the purpose, ideally white so the lice can be seen easily and with teeth no more than 0.3mm apart in order to trap head lice - research has found detection combing was four times more effective than visual inspection
Step 3
Ensure the lighting in the room is good
Make sure you divide the child's hair into sections and insert the comb at the roots before gliding outwards
Step 4
You are looking for a living, moving louse. They range in size from a full stop to a sesame seed depending on their age. When it first hatches, a young louse (known as a nymph) is transparent but after its first blood meal, it will darken to a greyish brown colour. Head lice live on, or very close to, the scalp and don't wander far along the hair shaft unless encouraged to move to a new head.
