Head Lice: Risk Factors & Causes

Head Lice
Written by Nancy

According to the Centers for Disease Control and Prevention, approximately 6–12 million children in the US over the age of 3 are prone to getting heading head lice each year. These parasites take sanctuary in their hair and can cause pain and discomfort if left untreated.

What Causes Head Lice Cases?

Lice are most commonly spread through physical contact, specifically head-to-head contact. Since they cannot jump great distances or fly, the only way they can move from one head to another is by crawling along the scalp and hair strands.

This tends to happen when two or more individuals make close physical contact. The proximity can make way for the lice to crawl through the hair and land on another’s strands. This can go undetected, and you may not know you have head lice until your scalp starts feeling incessantly itchy or you exhibit other symptoms.

In addition to this, lice can also be transferred through objects that come in contact with the head. For instance, sharing hair ties and combs can greatly increase the likeliness of a lice infestation. If you share hair accessories, hats, or even bedding with somebody who may have head lice, it’s very likely you’ll end up getting them too.

It is important to note that head lice affect only humans. Your pets are at no risk of getting them from you and vice versa.

Who May Be At Risk of Head Lice?

Now that we’ve determined what causes head lice to spread, let’s take a look at who’s most likely to be affected by them.

School going kids are most prone to lice attacks. While head lice can spread in older kids and adults as well, younger kids are more likely to be affected due to the skin of their scalp being less acidic. As a result, it isn’t as effective a barrier against parasites and is rather vulnerable to them.

The Different Types of Lice and How to Tell if You Have Them

People who have long hair or wear it loose are also at greater risk. This is because long, open strands create a pathway for the parasites to crawl on. Additionally, people who regularly share hair accessories and head apparel are also more likely to get head lice.

In cases where head-to-head (or hair-to-hair) contact is frequent among certain individuals, the chances of contracting head lice are increased. This includes activities such as participating in contact sports, having sleepovers, and staying at overnight camps.

To prevent the onset of a lice infestation, it’s important that you have regular screenings. Lice Troopers in Plantation offers lice removal services to prevent and treat the outbreak of head lice. This includes salon treatments, school screenings, and home inspections.
