Yes, it is possible to kill head lice nits. Head lice nits are the eggs that female lice lay on the hair shaft near the scalp. These eggs have a hard shell that protects them from most treatments, so they can remain viable for up to 10 days.
The most effective way to kill head lice nits is to use a fine-toothed comb to physically remove them from the hair. This should be done after a hot water wash and a thorough conditioning of the hair. The comb should be used to gently comb through the hair, starting at the scalp, to remove any nits that may be attached to the hair shaft.
In addition to physical removal, there are several chemical treatments available that can effectively kill head lice nits. These treatments typically contain an insecticide such as permethrin or pyrethrin, which can be applied directly to the scalp or hair. It is important to carefully follow the instructions on the product label and to use the product as directed.
In some cases, it may be necessary to use a combination of physical removal and a chemical treatment to effectively kill head lice nits. If the infestation is severe, a doctor or healthcare provider may recommend a prescription medication to treat the lice.
It is important to note that it can take up to two weeks for all the nits to hatch and for the lice to die off, so it may be necessary to repeat the treatment multiple times. Additionally, all members of the household should be checked for lice, and any clothing or bedding that may have come in contact with the lice should be washed thoroughly.
