If you put a cat or dog flea collar on a girl's ponytail, is that an effective way to kill head lice?

In brief: No!
Flea collars are designed to kill parasites that infest cats & dogs, not human head lice.
Not only would it not work, but there is some evidence that the chemicals in flea collars might be toxic to children, particularly young ones. There are several effective fda-approved treatments for head lice; stick with those.
