Frequently Asked Questions FAQ

What is a Robi Comb?


The Robi Comb is a patented electronic comb used to detect and kill head lice. Robi Comb destroys lice on contact simply by combing it through dry hair. When the electronic Robi Comb touches lice, they get zapped, die and are combed out of the hair.


Why is the Robi Comb better than other treatments?

  • Robi Comb Detects Lice
    The Robi Comb can be used to quickly detect lice in an non-invasive way. The Robi Comb lets you know by an audible signal whether or not head lice are present, so it can be used to detect an infestation. In fact, many school nurses use the Robi Comb for exactly that reason.
  • Robi Comb Kills Lice Quickly and Easily
    Using the Robi Comb is as simple as combing a child's hair for a few minutes a day. Compare that to other treatments where a child needs to sit still, sometimes for hours, while dangerous and sometimes painful gels are put in their hair! The Robi Comb is a painless and efficient way to help prevent infestation or re-infestation.


  • Robi Comb Kills Lice Without Toxins / Pesticides
    Toxic shampoos are a common method for Killing lice. These products to get rid of lice use pesticides such as Pyrethrumor Permethrin. These chemicals are toxic and attack the louse's nervous system.
    Many people are wary of using these products due to concerns regarding overexposing children to the pesticides.
  • Robi Comb is Safe
    As the Robi Comb does not use any toxic chemicals or oils, it is safe for children with colds, asthma, or any other respiratory conditions, who may have reactions to chemical treatments. 
  • Robi Comb is Recommended by Healthy Child Healthy World
    Healthy Child Healthy World recommends Robi Comb as an excellent way for parents to help reduce their children’s exposure to potentially harmful chemicals.
  • Robi Comb is Used on Dry Hair
    Being able to treat lice on dry hair eliminates the drama of lice treatment. There is: NO special gloves to wear, NO application a pesticide shampoo / gel or oil, NO worrying about exposing eyes or face to toxins, NO waiting hours for results, NO mess and NO odor.
  • Robi Comb Can Be Used Anywhere
    Robi Comb can be used in just a few minutes on dry hair: at school, in a car, at the park... anywhere. It is travel sized too, and can be stored in any dry place.
  • Robi Comb has no Odor or Fragrance
    Robi Comb is not a chemical treatment and has no odor of any kind.
  • Shampoos Do Not Kill Resistant "Super" Lice
    Scientific studies as well as reports from school nurses and parents, document how lice are becoming resistant to chemical treatment. 
  •  The Robi Comb is a safe and non-toxic alternative. A louse cannot become resistant to the Robi Comb, which zaps lice with an electric pulse.


What about the Nits (lice eggs)? Does Robi Comb kill them too?

Nits are lice eggs that are glued to the hair by the lice. Robi Comb does not kill lice before they hatch, it kills lice as soon as they hatch. If lice are found, the Robi comb should be used daily to kill all newly hatched lice. This breaks the cycle, as lice do not live long enough to lay new eggs.

We recommend using the Robi-Comb each day for ten to twelve days while the eggs are hatching to kill the lice as they hatch. At the end of twelve days, all of the eggs should have hatched, and there will be no live lice left to lay eggs and no eggs left to hatch. We also recommend that when the child returns to school, the
Robi Comb should be used for a few minutes every other day for as long as there is a problem in the classroom to detect and kill any lice which may have transferred to the child's scalp

Do Shampoos Kill Nits?

Pesticide-based medications have limited success against Nits as well, because young nits don't have a central nervous system for the pesticides to effect. Pesticide shampoos generally leave a toxic residue on the hair for a few days, which can kill the lice as they hatch. Of course that means that you have poisons on your head for a few days as well! As children scratch their heads during this time, poisons can get into the scalp as well as on their fingers.

Shampoo manufacturers recommend a second application of the shampoo seven to ten days after first use, which is the time it takes for the newest eggs to hatch. This is their way to break the cycle.  


How do I Remove Nits Then?

Nits are not only unhatched lice, the word "Nits" also describes the empty shells of hatched lice that are still glued to your hair. Nits can be removed using a non-toxic shampoo such as LiceGuard's SAFE Lice Egg Removal Shampoo. It has an original formula that softens and untangles the hair and has been shown to be very effective in removing nits. In a clinical trial, LiceGuard SAFE Lice Egg Removal Shampoo removed 85% of the nits in one group of children after just five minutes of combing with a fine-toothed comb, compared to only 25% of the nits when LiceGuard SAFE Lice Egg Removal Shampoo was not used.

After Nits have been loosened by
SAFE Lice Egg Removal Shampoo, the wet hair should be combed with an Egg & Lice Comb, which pulls the Nits off the hair.

Nits can be removed in this way right after using the Robi Comb. Both the
Robi Comb and our SAFE Lice Egg Removal Shampoo are non-toxic and can be used as often as you like. There is no need to wait between treatments as with toxic shampoos.

If you wish to purchase both the Robi Comb and our SAFE Nit Shampoo and Lice Comb, take a look at the
Family Special deal- it also contains our Lice Repellent Spray.


How do you make sure the Robi Comb is clean, if you use it to detect lice on many children?

There are two things to be concerned about in these situations. First, it is important to avoid transferring lice from one scalp to the next. Fortunately, Robi Comb signals when it has trapped a louse. Before resuming the combing process, or using the comb on another child, the teeth should be inspected and the dead louse removed with the cleaning brush which accompanies the comb. Second, to sanitize the comb, recommended to use 91% isopropyl alcohol. The alcohol should be poured onto a cotton ball which you can clean the comb's teeth and the surrounding plastic area.  

School nurses may wish to use a spray germicidal instead of the alcohol. Because excessive moisture on the comb will prevent it from working, and since it takes a while for the toothed-comb to dry, we suggest that when screening a large number of children, you should consider using two Robi-Combs, so that one can be cleaned and dried while the other is in use. A portable hair dryer can also help speed the drying process.
