Do Lice Like Clean Or Dirty Hair? Let’s See

If you’re like most people, you might shudder and reach up to reflexively scratch your scalp at the mere mention of head lice. But head lice have been around for as long as humans have been alive.

In fact, we have coexisted since ancient times — which is why even mummies from ancient Lice have been found in Egypt. It is therefore likely that you or someone you know will come into contact with these tiny creatures at some point.

Others have heard the rumor that lice actually prefer clean hair, while some have questioned whether hygiene plays a role in catching lice. Read on to learn what the science has to say about which is actually the case.

What Are Head Lice?

Head lice, or Pediculus humanis capitus, are tiny insects that attach to the base of the hair shaft on your head and neck. They stay close to the scalp because they feed on blood several times per day. An adult louse will expire in one to two days if its blood supply is not active.

There are three stages to the life cycle:

Eggs: They are referred to as nits. They are attached to the hair shaft near the base at the scalp and can often be confused with dandruff or hair spray droplets. Within half a centimeter of the scalp, they are yellow to white in color.

Nymphs: Nymphs emerge from the egg and resemble adult lice, but they are very difficult to spot. They usually have the size of a pinhead.

Adults: With six legs, each with a tiny claw, the adult louse is about the size of a sesame seed. They are tan to grayish white, but they often appear darker in people with dark hair. Female lice have a daily egg-laying capacity of up to 10 and can survive up to 30 days on a person’s head as adults.

Do Lice Like Dirty Hair?

Lice are fans of ALL sorts of hair, however, among the common myths about lice is that lice prefer dirty hair. You might be surprised to learn that lice prefer a clean head to a dirty one because it is simpler for them to grab hold of the hair. Consider how challenging it is to grasp an oily rope. A rope that is clean, however, is easier to get a grip on. In this case, lice use the hair as a rope to climb from one person’s head to another’s hair. This does not imply that you should stop washing your hair to prevent getting lice. Many people, especially busy parents and those with long hair, coat their hair in natural products like mousse, essential oils, or hair gel to act as a barrier against a lice infestation. This can be an effective protectant.

Do Lice Like Clean Hair?

For the reason mentioned previously, head lice cases are more prevalent in those people who rigorously shampoo their hair. If a human host is in close proximity to other adults, children, or family members who have head lice, they increase their risk of developing a head lice infestation. This is true even if they regularly wash their hair to try to keep live lice away. It is simpler for the insects to attach to hair that is not coated in oil or a product like a head lice repellent with essential oils, mousse, or gel to infest a new head; it is also simpler for adult lice to hang onto clean human hair once they have established a home; it is in this location that a female head louse will feed on human blood from the clean human scalp and subsequently lay her lice eggs (called nits – about the size of a sesame seed). So, contrary to what you may have heard, head lice prefer clean hair to a person with poor hygiene.

How to Prevent Head Lice?

The frequency of your showers or hair washes is irrelevant to head lice. There’s no tried-and-true way to prevent head lice, but you can take steps to lower your risk:

  • Avoid close head-to-head contact:Close contact at sleepovers, contact sports, and kid’s games may make lice more likely to spread. Just keep in mind that you won’t catch lice by simply being close to someone who does.
  • Avoid sharing clothing or accessories that touch your hair:Sharing hats, hair ties, barrettes, scarves, coats, and anything else that comes into contact with your head and hair for an extended period of time can spread lice.
  • Avoid sharing brushes, combs, or other hair styling accessories:Additionally, but less frequently, these items may spread lice. If you do decide to share these items, you can get rid of lice by soaking them in hot water for 5 to 10 minutes (at least 130°F, or 54°C).
  • Avoid lying on communal couches, beds, pillows, and stuffed animals:According to a reliable source, lice can survive in furniture and bedding for up to two days.
  • Always wash and dry bedding, clothing and other items:These items can be cleaned in hot water and dried on high heat to get rid of any lice present if someone in your home has head lice. Dry cleaning or putting something in a plastic bag for 14 days to ensure that all the nits die are other options if you are unable to wash it.
  • Vacuum your furniture and floor:Pay close attention to rugs and carpeted areas as well as furniture like couches and chairs.
