Pantene shampoo does not kill head lice. According to Kid Spot, Pantene conditioner can help with the prevention because it coats the hair and makes it difficult for lice to stick to it.
According to BabyCenter, there are many conflicting recommendations for head lice removal. The most recommended option is over-the-counter lice medicine that is available as a shampoo, cream rinse, gel, mousse and other forms of hair products. After the treatment has been applied, it's necessary to comb out the lice. It's important to repeat the treatment process nine days after starting it. This is done to kill any lice hatched after the original treatment.
