Yes, it is possible to kill nits (lice eggs) with shampoo. Shampoos that are specially designed for killing lice and nits contain an active ingredient such as Pyrethrin or Permethrin, which are insecticides that are effective against lice. These shampoos, when used as directed, can help to break the life cycle of the louse, killing both the adult lice and nits.
It is important to note that shampoos are not a cure-all for lice infestations and may not be effective against certain strains of lice. Therefore, it is important to consult a doctor before treating lice with shampoos to ensure that the shampoo is the right choice for the specific strain of lice.
When using a shampoo to kill nits, it is important to follow the directions on the package carefully. First, the shampoo should be applied to all areas of the scalp and left on for the recommended amount of time (usually around 10 minutes). After the shampoo has been on the hair for the appropriate amount of time, it should be rinsed off thoroughly with warm water. After rinsing, the hair should be combed with a lice comb to remove any remaining nits. This process should be repeated every three to five days for two weeks to ensure that any newly hatched lice or nits are killed.
Overall, it is possible to kill nits with shampoo; however, it is important to use a shampoo that is specifically designed to kill lice and follow the directions carefully to ensure the best results.
