Hair lice are medically known as head lice, and small children with head lice can be improved by general treatment and medication. 1. General treatment: For small children with head lice, it is recommended to remove the hair, or if this is not acceptable, comb the hair with a close-toothed comb to remove the lice and nits. Personal items such as bed sheets and clothes should also be sterilized. 2. Medication: Parents can rub the head and neck area with Benzyl Benzoate, Vaseline and other medications, which can effectively kill adult lice and nits and relieve the symptoms. If a child suffers from head lice, parents are advised to take the child to a regular hospital for treatment under the guidance of a doctor.
