Should I use lice shampoo two days in a row?

No, you generally should not use most lice shampoos two days in a row; instead, follow product instructions, which often involve a second treatment 7-10 days later, and use a fine-toothed comb daily, as applying it too soon risks scalp irritation or resistance and doesn't improve effectiveness, only requiring a repeat in a week to kill newly hatched lice. Always check the specific product's label, as some newer or natural treatments might have different guidelines.

Do head lice stay alive on pillows?

Yes, head lice can briefly live and crawl onto pillows after falling off a human host, but they die within 1-2 days without a blood meal from a human scalp, making pillows a low risk for transmission; nits (eggs) won't hatch off the scalp and need heat to survive, so washing bedding in hot water kills them effectively. The main risk is head-to-head contact, not furniture or bedding.
