You can use Elimax® as often as you like. Elimax® Shampoo is particularly suitable for frequent hair washing. One or two treatments will usually be enough to get rid of the tiny creatures. But there is always a chance of catching them again from people who haven’t been treated. Elimax® can always be used again, at no risk. And it will be just as effective. Elimax® has a physical mode of action and does not contain pesticides, so the head lice cannot develop resistance. Washing your hair with Elimax® Shampoo is as effective as washing with an ordinary 2-in-1 type shampoo.
