Egg Stage: The female louse lays the egg with a special glue that cements it to the hair shaft near the root. The eggs develop and hatch approximately 10 days later.
Nymph Stage: Once the louse hatches, it is called a nymph and is barely visible to the naked eye. The nymph cannot reproduce because it is not fully developed. After about 12 days, it becomes an adult.
Adult Stage: The adult louse can lay up to 4-10 eggs a day - starting another generation of lice. The adult stage lasts about 28 days.
