Early signs of lice include intense scalp itching (especially behind ears/neck), a tickling feeling, and tiny, oval, yellowish/tan/brown dots (nits) stuck firmly to hair shafts near the scalp that don't brush off like dandruff; you might also see fast-moving, sesame-seed-sized grayish-white or tan bugs, but finding nits is more common initially.
Key takeaways. Head lice are about the size of a sesame seed and are typically grayish-white or tan. They can adjust their color to blend with different hair shades. The most common symptom of a head lice infestation is an itchy scalp, resulting from an allergic reaction to lice bites.
Head lice are parasitic insects that usually live on your scalp. Symptoms include itching, tickling, or sores on your scalp. Both prescription and over-the-counter medications treat head lice infestations.
Medicated lotions and sprays

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.
Getting head lice isn't a sign of poor hygiene or unclean surroundings. Head lice prefer clean hair to attach and lay their eggs. Another common misconception is that head lice can jump or fly from one person to another. Head lice only crawl, most often leading to transmission through direct head-to-head contact.

The life cycle of the head louse has three stages: egg, nymph, and adult louse. Nits are lice eggs. They are hard to see and are often confused for dandruff or hair spray droplets. The nit is laid by the female near the base of the hair shaft and usually takes about 8-9 days to hatch.
Body lice live in your clothing and bedding and travel to your skin several times a day to feed on blood. The most common sites for bites are around the neck, shoulders, armpits, waist and groin — places where clothing seams are most likely to touch skin.
Use fingers to separate hair and create a part. The part should allow you to clearly see the person's scalp. Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed.
Launder clothing and bedding immediately before lice treatment on your child so any live lice living there can't crawl onto lice- free, just treated heads! Laundry water should be at least 130 degrees Fahrenheit to kill the lice. CAUTION: Do not bathe or shampoo in water this hot! This temperature is for laundry only!
Most children who are exposed to someone with head lice do not get them. Lice cannot jump or fly. They can only crawl. Lice are only passed to others by close head-to-head contact.
