Why Are Head Lice Less Common in Adults?

Adults are less likely to get head lice compared to children, but anyone can get them. The usual culprit is head-to-head contact, but adults can also contract head lice in a number of other ways. One of the most common is if they have visited a country where head lice are more common. In countries like the Netherlands, parents are less strict about removing lice are spread to a higher percentage of the population than they are in the US.

Adult head lice are 2 to 3 millimeters long and can be white or tan. They have six legs, including claws, and can latch onto the hair. If they remain on the head, adult lice can live for up to 30 days. However, once they fall off, they will die within one to two days.

One reason why adult head lice are less common is that people in the United States do not live near children. Children are more likely to encounter lice because they have less respect for their personal space. This makes it easier for the bugs to infest hair and other clothing. However, adult head lice can still infest adults if they live in close quarters with kids.

Medicated shampoos and creams can help kill lice. They may be purchased over-the-counter or through a medical practitioner. However, you should not use these products on children younger than two years. Medicated shampoos should only be used when a lice infestation is suspected, and it is best to seek medical advice before using them on a child.
