Question: what do a lice look like?
Answer: What do lice look like? An immature louse (or nymph) looks like an adult, but it's about the size of a pinhead. After a week after hatching, the louse grows to the size of a sesame seed, with six clawed leg and a tan to grayish-white color. Note that the CDC says lice may look darker on people with dark hair.
