By removing adult lice and their eggs on a regular basis, effectively you will break the head lice cycle. In between treatments use KP24 Combing Solution regularly with the KP24 lice comb, and this will aid against reinfestation and can help you keep lice free. Apply KP24 Combing Solution generously to damp, tangle-free hair. Divide hair into segments and comb close to the scalp to remove adult lice and their eggs. Repeat 3 or 4 times or until lice free.
