Lice eggs seem indestructible! No matter how hard you try, they always seem to come back! One treatment I’ve heard about, though gross, is actually very good at killing both the eggs and lice. Take a jar of Vaseline and apply it to the hair, then use a shower cap to keep it in place. This should stay on for at least a week. It should kill all of the bugs and eggs at once! Getting it out of the hair is the harder part. If this is a bit too much for you, sprays and shampoos from a store should do the trick as well.
