The Stages of Lice Development


Lice begin their journey in an egg. These eggs are also known as “nits,” and you might hear this term used at our Houston lice treatment center. Nits are laid by adult female lice and are almost always found close to the scalp. In most cases, they are planted at the base of a hair shaft. They are incredibly small, with most eggs measuring approximately .8 millimeters by .3 millimeters. Between their small size and white-yellow coloration, it’s no surprise that many people mistake nits for dandruff. These eggs typically hatch after six to nine days and develop into nymphs, which we will discuss in the next section.

Once an egg has hatched and released a nymph, the shell remains attached to the scalp and turns a dull shade of yellow. Nymphs are approximately the size of a pinhead, which makes them difficult to spot in individuals with longer hair. They grow quickly and reach adulthood after approximately a week, at which point they begin feeding several times each day. This is also the point at which many people begin to feel the sensation of lice in their hair.


Adult lice are between 2 to 3 millimeters in size, or approximately the size of a sesame seed. They’re still difficult to spot with the naked eye, but they can be seen if you’re looking closely. Adults can live for up to 30 days, and females can lay up to 8 nits per day. That means that each female louse on a person’s scalp can lay up to 240 eggs in one lifetime! At that rate, it’s no surprise that lice infestations get out of hand so quickly.
