Parasidose 2 in 1 Lice Lotion. The lotion has a 2in1 effect and the composition is effective against lice and nits. The formula consists of two phases that must be mixed before the first use. The active ingredient consists of one substance, Prosil, and the lice protection factor (LPF). The patented Prosil has been specifically selected for an optimal effect on head lice. The dual action blocks the breathing holes of the louse, and begins to dehydrate and dry the insect's skin after 10 minutes. Composition free of parabens, silicone and insecticide.
