If you mean head lice, here's how to treat them.
First, use a medicated lice shampoo. Shampoos containing permethrin or pyrethrin are common. Apply the shampoo to wet hair and massage it into the scalp. Leave it on for the recommended time according to the product instructions, usually around 10 minutes, and then rinse thoroughly.
After using the shampoo, use a fine - toothed comb to remove the dead lice and nits (lice eggs). Comb through the hair section by section, starting from the scalp and working towards the ends.
Wash all bedding, hats, and clothing that may have come into contact with the lice in hot water and dry them on a high - heat setting to kill any remaining lice. Repeat the treatment process about a week later to make sure all lice and nits are eliminated.
