wash the hair for three continuous days with dandruff shampoo
isolate all clothing of the child for one week
treat with an approved pediculicide agent according to directions
shave the child’s head, then cleanse with herbal shampoo
Number 3 is correct.
Treating hair lice most commonly requires application of an over-the-counter pediculicide (medication that kills lice). Leave on the hair according to label instructions. If the child has long hair, a second bottle may be necessary. Washing the hair with dandruff shampoo is ineffective. For clothing and items that cannot be washed in hot water/hot heat drying, sealing them in a plastic bag for two weeks is recommended. Shaving the child’s head and cleansing with herbal shampoo is ineffective.
