Helpful Information for School Nurses

We realize you amazing school nurses are on the front lines of detection and finding head lice on students can be stressful for both the children and teachers. We don't want it to be stressful for you too. Here you'll find tips to share with your parents as well as printables and links to studies.

Examples of School Lice Policies:

Many schools or school districts take different approaches when it comes to head lice policies in their schools. Here are three main policies.

No Nit

No nit policies require a student to be free of nits and bugs before they can return to school.

Live Bugs Only

Live bug only policy indicates students must be free of all live bugs before they can return to school. Nits in the hair are ok. Some believe that if all lice bugs are out and only nits remain then the case is no longer active.

No Exclusions for Head Lice

Parents are notified of their child's case of head lice, but are allowed to stay in school. Children are not excluded from school because of head lice. It is expected that parents treat before the child returns the next day.

Which policy is best?
There are many reasons, positives and negatives to each of these policies. While it may be best to send children home when head lice is detected and not have them return until they are free from lice and nits, it's not always possible. Many parents try for weeks or even months to get rid of head lice, but just can't seem to get rid of it. That can be costly when parents miss work in addition to the burden on the child missing school.

Here are some helpful tips for creating a head lice policy/note to parents:

  • When recommending treatments manual removal of head lice with a good head lice comb should be the first recommendation as it is also the safest. OTC and prescription strength pesticides are meant to be a “when all else fails” last ditch effort.
  • It is important to inform parents of all treatment options as well as any risks.
  • Educating parents on the fact that head lice do not live in the environment and focusing on the head should be stressed.
  • There are professional head lice services that may be a valued resource for you and your parents. These companies can help provide proper education to staff and some may even provide back to school notes after treatment; relieving school staff of the responsibility of checking and enforcing policies. Many companies are certified lice professionals with in depth training and receive up to date information on head lice research, product information and treatment options.

  • Because itching is due to an allergic reaction to head lice saliva not everyone with head lice will itch. So, all students need to be screened
  • Screenings that do not include people of certain ethnicities should be abandoned as any human can get head lice. There are no exceptions based on ethnicities or hair texture.
  • Constant communication informing parents of newly detected cases of head lice by Informing all parents/caregivers via notes, emails, or school wide phone message is important to help both parents and schools work as a team.

Recommend manual nit removal
Recommending manual head lice removal with a good head lice comb helps reduce the exposure to pesticides. The OTC products parents and caregivers use to treat head lice are often more dangerous than having head lice. Over the counter products with chemicals and prescription treatments could always be used as a last ditch effort.

Refer them to a professional
Professional lice removal specialists have so many benefits besides the service of removal. They can thoroughly check all household members to make sure parents are treating only those affected by lice. Also, in some cases head lice has been misdiagnosed and no treatment is needed at all. Professionals also sell the best lice combs. This is extremely important because having the right comb can save hours of combing especially on long, thick hair. In addition, most lice professionals sell only products free from chemicals that are safe, non-toxic and effective. Most importantly, they have the right information to save parents a lot of time and energy otherwise spent on getting rid of lice. Many parents feel much less stressed after speaking with or visiting a professional.

Common Myths:

Mayonnaise​​, Olive Oil, Vaseline/Petroleum Jelly
These products are used in hopes of suffocating head lice. Head lice are able to shut down their bodies for long periods of time even fully submerged in substances meant to kill them. These products may suffocate the bugs if used for hours on end, but they do not kill the eggs.

Cetaphil also known as the Nuvo method
This dry on suffocation method was created by a dermatologist who has unfortunately admitted that this method was nothing more than a get rich scheme. Originally dubbed as the Nuvo method and charged $284 for the lotion, it was actually the Cetaphil face cleanser. Check out our "studies" section for the articles documenting this deception.

Apple vinegar, white vinegar, Coca Cola
It is assumed that these products help dissolve the glue that holds the eggs to the hair shalft. This glue make up is similar to human hair. Substances found to dissolve the glue also dissolve the hair. These products are not only ineffective, they leave the hair feeling like straw.

Spraying the house down and bagging everything for weeks
False! Lice sprays are money wasting gimmicks as head lice do not live in the environment. Because head lice is mistakenly grouped in with body lice in their stigma of hygiene and often times research: many believe that because body lice lay eggs in clothing and survive for days away from a human host that bagging items will help kill head lice and their eggs. A louse found off the head is usually injured or dying.

You know when you contact head lice right away
False! Head lice symptoms can take 24 hours to 4 weeks to show up. Some people are asymptomatic meaning they never develop symptoms. Most case of head lice are not discovered until 3-5 weeks later.

Eggs more than a quarter inch off the scalp are dead
False! Because there is no way to know when an egg was laid without looking under a microscope you do not know when eggs will or will not hatch. To remove to risk of eggs hatching and starting the life cycle over again, all eggs must be removed.
