La Lendrera Antilice Newell acts against lice and nits. The double micro-channel prongs effectively remove lice and nits without damaging the scalp. It is recommended to start treatment only when live lice are seen. How to use: - Wash hair with a mild shampoo and conditioner, if necessary, to detangle hair. - Divide your hair into small sections and work on each section individually. - Pass the comb along the hair, from the roots to the ends. - After each pass, inspect the comb to make sure you have caught lice and nits. - Clean the comb regularly during the process and after each section. - Wash and disinfect the comb after use. - Repeat this process several times, especially in the following days, to ensure that the lice and nits are completely removed.
