In theory, yes, since the lice that dwell in our hair are specifically adapted to this habitat and can't survive in the fur of other animals. So if no one had any hair, the itchy critters would have nowhere to live.
Yes, head lice can briefly live and crawl onto pillows, but they can't survive long (usually 1-2 days) without a human host for blood meals, and nits won't hatch without scalp warmth, making pillows a low risk for infestation, but washing bedding in hot water is recommended to kill any stragglers.
