Frequently Asked Questions

Head lice are tiny, wingless insects that live on the scalp and feed on human blood. They are common, especially among children, and are not a sign of poor hygiene.

Head lice spread mainly through direct head-to-head contact. They can also spread by sharing personal items like hats, combs, or hair accessories, though this is less common.

The most common symptom is itching on the scalp, caused by an allergic reaction to lice bites. Some people may also feel a tickling sensation or notice lice or eggs (nits) in the hair.

No, head lice are not dangerous and do not transmit diseases. However, scratching can lead to irritation or secondary skin infections if not treated properly.

While head lice are more common in children, adults can get them too—especially if they are in close contact with someone who has an infestation.

“Super lice” are head lice that have developed resistance to some common over-the-counter treatments, particularly those containing pyrethrins or permethrin. They are not a different species—just harder to kill with certain products. In these cases, alternative treatments (such as non-chemical methods) may be more effective.

Children usually get head lice through close head-to-head contact with other kids, especially in places like schools, daycare centers, playgrounds, sports activities, and sleepovers. Lice crawl from one person’s hair to another—they do not jump or fly.

The ROBICOMB is an innovative solution to the age-old problem of lice. It is an electric lice comb specially designed to electrocute lice on contact as the comb slides through clean, dry hair. When working properly the device makes a soft, high-pitched sound. When it comes in contact with a live louse, the comb “zaps” the louse with a small electric charge. The sound will temporarily stop to alert the user. After being “zapped,” the louse will die instantly or soon after and will be unable to lay any more eggs. Simply use the included brush to remove lice from the combing surface and resume combing.

The ROBICOMB will “zap” most average-size eggs assuming the comb user is meticulous; however, because the eggs are glued to the hair, manual removal is often required. Eggs are laid very close to the scalp (less than 1/8”) and you must be thorough about sweeping the ROBICOMB down to the hair roots across the entire scalp. As a precaution, continue using the ROBICOMB for a full two weeks to eliminate any “missed” eggs and newly hatched lice. Although the ROBICOMB may kill the eggs, you may still need to manually remove egg/nit remnants. For this, we recommend the Lice & Egg Elimination Kit, which includes a professional-grade lice comb and specially formulated shampoo to loosen the bonds between eggs/nits and hair.

Yes. The ROBICOMB can quickly detect lice by combing it through a child’s hair. If the buzzing sound stops, lice are likely present—but always verify visually. This feature is particularly great for classrooms and daycare. The ROBICOMB may also detect eggs that are large enough to be zapped. Nits (empty or dead eggs) are rarely large enough for the ROBICOMB to detect, so a visual check should always be done after treatment.

Yes. The ROBICOMB is the only lice treatment product that can be used again and again to detect and kill lice. Simply clean the combing surface between uses to prevent contamination.

Use the included brush to remove debris. To sanitize the teeth, use isopropyl alcohol or a germicidal spray. When screening multiple children, consider using multiple combing units so one can be cleaned and dried while another is in use.

To treat an infestation, use at least once daily for a minimum of two weeks. As a precaution, use once a week or as often as needed during an outbreak in your area

Yes. The ROBICOMB requires one AA battery. Pull off the bottom plastic cover and insert the battery, making sure to align the + and – signs.

The buzzing sound indicates the ROBICOMB is powered on and working properly. When the buzzing stops, you’ve zapped a louse. Verify visually, brush off the combing surface, and resume combing.

Most likely you have zapped a louse. Verify visually, brush off the combing surface, and continue combing. Sometimes debris in the hair (like lint or dandruff) can trigger the device to stop buzzing. Ensure hair and the combing surface stay clean and dry.

1. Verify the combing surface is completely clean and free of debris.
2. Remove the plastic housing and turn the power switch on. If it buzzes without the combing unit attached, the issue is with the combing unit. Remove and inspect the metal combing unit—ensure none of the teeth are touching, especially at the ends. If they are, gently pry them apart. Reassemble and test again.
3. Check that a fully charged battery is inserted.
4. Confirm the power switch is set to “ON.”

If the problem persists, contact customer service for a replacement combing unit.

The comb is designed for human head lice. It has not been tested for other uses, but some customers have reported success using it to remove fleas.

Ensure the hair is completely dry. Moisture conducts electricity and can cause the ROBICOMB to stop buzzing. If the issue continues with dry hair, contact customer service for a replacement.

The ROBICOMB has insulated tips to prevent shocking the scalp, but direct contact with the shiny metal surface can cause a small shock or tingling sensation. If the unit shocks through the insulated tips when used correctly, the combing unit should be replaced.

The No-Nit Kit’s shampoo’s non-toxic, pesticide free formula loosens the bond between lice eggs and hair follicles, making it easier to comb out eggs with the included comb.

No. The No-Nit Shampoo is currently available in one size only.

The lice repellent hair spray’s non-toxic, pesticide free formula emits an aroma lice dislike—but people enjoy. Clinical trials show that a small amount repels lice for up to 24 hours. Apply a few sprays over the head and comb through; you don’t need to saturate the hair.

Yes. Use the ROBICOMB first on dry hair to kill or disable lice and eggs. Then use the No-Nit Kit to remove any remaining lice and eggs. Finally, apply the Repellent Hair Spray to prevent future infestations.

The lice repellent hair spray should be applied every morning and provides 24-hour protection. It comes in a 60-day supply bottle.

No. The Repellent Hair Spray should be the last product applied before leaving the house. Other hair products can mask the scent and reduce its effectiveness.

The kit includes professional-grade stainless steel lice combs, a dual hair pick/locator/magnifying tool to help identify and remove lice, eggs, and nits from the hair.

The combs are designed with tightly spaced metal teeth that physically remove lice and eggs from the hair shaft. When used methodically section by section, they help eliminate both live lice and stubborn nits.

While the comb can be used alone, it works best when paired with a lice treatment shampoo that helps loosen the attached eggs (nits) to the hair, making them easier to remove.

Yes. The combs are reusable and can be cleaned and sanitized with hot soapy water or isopropyl alcohol after each use.

Pay special attention to:

• Behind the ears
• Nape of the neck
• Areas close to the scalp (within about ¼ inch)

These are the most common places lice tend to hide.
