Paranix Lice and Nit Killing Shampoo. The dual-action formula of Paranix 2-in-1 Shampoo not only suffocates lice and nits but also dehydrates them. It is also very convenient to use because it washes the hair at the same time, i.e. there is no need to use a cosmetic shampoo after the treatment. Paranix Lice and Nit Remover shampoo acts mechanically by suffocating and dehydrating the louse, making it less likely to generate resistance to the product.
