Head Lice are small wingless human parasites that make their home on the human scalp. Head Lice are incredibly well adapted to survive on their human hosts. Head Lice have developed many successful strategies to evade detection by their primary predator, humans! These strategies include different types of camouflage for the louse itself as well as lice eggs. Lice eggs are very difficult to remove from the human hair shaft. This is no accident. Head Lice removal treatment involves successfully removing all of the lice eggs.
