Help! My Kid has LICE!

It’s that time of year again. In the last month or so, head lice infestations have been reported at several area schools. These infestations are fairly common, as are parental overreactions. Yes, lice are icky and the mere thought of them make us itch; however, they are relatively easy to treat and do not carry or spread disease. Lice infestations are common among school-age children, and are NOT an indication of poor hygiene. They are spread by head-to-head contact and possibly the sharing of hats, combs, brushes, and other hair accessories. Head lice are only interested in humans. They are not spread by pets and cannot fly or jump, and can survive off the human host for less than three days.

Looking for Lice

If lice have been reported in your child’s classroom or school, it is a good idea to do a head check, especially if you notice your child scratching. The itching is caused by a local allergic reaction to lice saliva. Lice can be hard to see, so using a bright light and magnifying glass, and separating the hair can help. During an infestation, a child or adult will usually have fewer than twenty live lice. Look for live lice or their eggs (nits) which are glued onto the hair shaft at an angle. And, if you find lice on one kid, you probably want to check the others . . . and yourself.

Treating lice

If you find lice, the next step is to kill them. The most effective treatment is permethrin, available over the counter as Nix. This is the least toxic of the available treatments and fairly easy to use. It is most effective when applied to dry hair. You must also remove the nits and any live lice that remain once the treatment application is complete. This can be done with a nit comb, which is typically included in the package or can be purchased separately (brand name: Lice Meister). A recent study showed that plastic combs were as effective as metal and easier to use. Using conditioner to make it easier, thoroughly comb through small sections of the hair. Finding nits or lice when you comb does not mean the treatment didn’t work. You should comb out the hair every three days until you stop finding nits or lice. The permethrin treatment can be repeated after seven days.
Other prescription treatments are available through your doctor but these tend to be more toxic and are generally reserved for lice that are resistant to permethrin.

All bed linens and recently worn clothing and hats should be laundered in hot water and dried in the dryer. Combs and brushes should be soaked in hot water for ten minutes. Things that cannot be washed should be vacuumed. Bleach is unnecessary, as are lice sprays.

Alternative treatments

There are many alternative treatments for lice. Most are not as effective as permethrin, and few have been formally studied. Lice are fairly difficult to kill by suffocation, but this can be done by coating the hair with olive oil, mayonnaise, or petrolatum (Vaseline) and covering the head with a shower cap. This can take up to six hours to kill all the lice, and the oil or petrolatum can be difficult to get out of the hair. Using a nit comb alone can be effective but takes multiple treatments and can be very time consuming. Shaving the head is only temporarily effective and therefore not recommended. Heat (hair dryers, etc), which seems to work only about 50 percent of the time, is also not recommended.

Bottom Line: Don’t freak out!

Yes, lice are gross and make our skin crawl, but they won’t harm your child and are easily managed. Keeping the hysteria to a minimum helps everyone through this situation. If you have more questions, contact your family doctor or pediatrician.

    Eeek, the memories of having my long curly hair pulled and combed through for hours after coming home from summer camp with lice. This is one downside to letting my boys hair grow long.

    Thanks for the info. Having 4 school age kids, I am always worried about this!

    I was wondering if anyone has tried the all-natural lice prevention shampoos that are being marketed right now. They are intended to be used every day as a preventative measure. I heard about one called “Fairy Tales” made with a blend of citronella, rosemary, and some other natural oils and extracts. Seems like a good idea, but I’m a bit worried my kids will end up smelling like some sort of aromatherapy experiment!
    Anyone given these products a try?

    It’s important to let people know that there are ‘super lice’ these days. These are lice that are resistant to most insecticides. If the lice don’t go away when you use a toxic shampoo once, don’t do repeat treatments as you are doing more harm than good.

    The key to effective treatment with non-toxic methods is to diligently interfere with the life cycle of the lice.

    Also, adding some lavendar oil (just a drop or two to a spray bottle)to a detangler solution of water and detangler is a known deterrent to keep your kids from getting them in the first place. Many people also use tea tree oil the same way, but it can be very drying this time of the year. We use it daily all year round (it’s good for bedhead too 🙂
    Plus then your kids will have hair that smells good and is soft too…..
    Also, lice really like clean hair, so washing it too often is NOT a deterrent and can make little scalps very itchy this time of year.

    Moms with little girls and curly top boys, it may be helpful to cut your kids’ hair before using the nit comb. I had hair down to my bum as a kid and combing that mess with that teeny little comb was torturous. I know long beautiful braids are a mom’s pride and joy, but it may not be worth the war. Give ’em some extra jello snacks over the next couple months and you’ll be surprised how fast it grows back!

    I’d love to know where to find the preventative aromatherapy shampoo Jaci mentioned. This sounds like a Whole Foods item–what’s it called?

  7. Jaci Arnone Jaci says:

    I know that the Fairy Tales products are available on line http://www.fairytaleshaircare.com

    I would bet Whole Foods carries some sort of equivalent. I’ll check it out the next time I’m there.

    Sarah, thanks for the tip about adding lavender oil to detangler, this might be an easier option.

    My daughter’s school recently had an outbreak of lice. We were advised to use an organic, pesticide free product called Quitnits… http://www.quitnits.com

    You can find it at CVS but it tends to be in the specialized shampoo area, e.g. dandruff
