Head Louse: The only known host for the head louse (Pediculus humans capitis) is humans. It doesn't have wings, so it jumps from one human host to the next. They are insects the survive solely on the scalps of humans. For more info see: http://en.wikipedia.org/wiki/Head_louse

Head lice: are transmitted person to person. In terms of their evolution - I am a physician and I don't have that type of knowledge base.
