Derbac-M Liquid (Malathion), Which Is An Organophosphorus Insecticide That Kills Parasites Such As Head Lice, Pubic Lice And Scabies Mites.

Malathion Works By Blocking The Action Of An Enzyme In The Parasite Called Cholinesterase. This Enzyme Is Essential For The Growth And Survival Of The Parasite. By Inactivating It, Malathion Disrupts Vital Metabolic Processes In The Parasites And Ultimately Leads To Their Death. Derbac-M Liquid Kills Lice And Their Eggs And Scabies Mites

Hedrin Lotion And Lotion Spray (Dimeticone), Which Is A Silicone-Based Substance. The Dimeticone In Hedrin Lotion Works By Physically Coating The Lice. This Stops Them Moving And Feeding And Also Prevents Them From Being Able To Excrete Excess Water. Both Actions Kill The Lice. Head Lice Cannot Become Resistant To The Lotion Because It Works In This Physical Way.

[The Lotion Doesn’t Kill The Eggs, So Treatment Needs To Be Repeated After Seven Days To Kill Any Lice That Have Hatched From Eggs Since The First Application. If The Head Lice Come Back, The Treatment Can Be Repeated Straight Away]
