To get rid of nits, or lice eggs, a person should use a medicated shampoo and a fine-toothed comb to remove the nits from the hair. Some strains of lice are resistant to the medicated shampoos. If this is found to be the case, a physician may order an oral medication to kill the lice.
Lice lay their eggs, called nits, on the hair shaft. Nits resemble dandruff except that they cannot simply be shaken out of the hair. It is necessary to follow a few steps to kill and remove the lice and nits from a person's hair.
Step 1: Confirm an infestation of lice
It is dangerous to use lice shampoo if the bugs are not present in the hair. Have an experienced professional confirm the infestation and recommend a brand of shampoo.
Step 2: Use a topical medication to kill the lice and nits
A topical medication such as a shampoo, rinse or lotion can be used to kill the lice and nits. Follow the directions on the bottle for proper application.
Step 3: Use a fine comb to remove the nits
Since nits are attached to the hair shaft, they may not rinse out with the shampoo. To remove all the nits, carefully comb through the hair with a fine-toothed comb made especially for nit removal.
