Are lice shampoos potentially hazardous?
Parents should be informed about the potential risks before they shampoo with any product. This is just one of the reasons the FDA requires testing for safety before they give their approval. Safety varies from person to person just as the status of one’s health varies. Children who have had earlier repeated lice treatments may also be more vulnerable to side effects. The NPA warns against the use of any chemicals designed to kill or destroy head lice in individuals who have pre-existing illness, such as epilepsy, asthma, brain tumors, cancer or AIDS, and for pregnant or nursing women. Those on medication should also be aware that there can be unspecified chemical interactions.
