It is not necessary to treat the hair just because you were exposed to lice, unless you see live lice or nits. If you are spending time around someone who has a head lice infestation (friend, family member, co-worker), you may consider using Licefreee Everyday! shampoo. Licefreee Everyday! is a homeopathic head lice shampoo containing naturally occurring ingredients that create an environment where head lice do not like to live.

No head lice do not fly.  They are transferred from head to head contact or thru items like hats, brushes, pillows and anything else which may come in conctact with your head.

The eggs take up to 14 days to hatch.  We recommend completing the treatment and do follow up head checks for the next 14 days.  If you find any live lice during that time we recommend completing the treatment again.

It is not necessary to retreat lice unless 1.) you find live lice, or 2.) you are following up with a second treatment as recommended 7-10 days after the first treatment. Some head lice treatments may dry the scalp and cause some itching and irritation.  Further, irritation may also be the result of using many different treatments. A deep conditioner may help restore moisture to your scalp post head lice treatment(s) to alleviate itching and dryness.

If you have treated your child with Licefreee Spray and then they are exposed to head lice again, they may be re-infested. You can help by teaching your children not to share personal items like hair brushes and hats with other children.

Thorough treatment and teaching your family not to share personal items will help prevent head lice infestation again.

Sources of possible infestation (bedding, furniture, hats, clothing, combs and brushes) must be disinfected by laundering/dry cleaning, or sometimes discarding entirely. Items that cannot be run through the dryer (i.e stuffed animals and toys) can be placed in a sealed plastic bag for 10-14 days, and hair care items should be soaked in hot water for 15 minutes. A thorough vacuuming will get rid of lice or egg shells that are left behind.

Teach your child to avoid sharing combs, hair accessories and hats. If your child has been infested with head lice, report it to their school immediately so other children attending will be less likely to have an infestation themselves.

Licefreee head lice nit combBecause Licefreee head lice treatments are effective in killing eggs as well as live bugs, you can choose to leave the eggs (nits) in the hair. However, if you desire, you can remove lice eggs with the stainless steel nit comb provided with the product, or with your fingernails.

Yes, we do! Our patented stainless steel nit comb (designed with the help of school nurses) is included with our treatments, Licefreee Spray!® & Licefreee!® Gel, to help remove dead lice and nits (head lice eggs).

Yes, head lice only lay eggs on the human scalp, they do not lay eggs on surfaces such as furniture or bedding.

There is no way to look at a nit with the naked eye and determine if it is dead or alive. And although some people claim it does, popping them does not prove that one way or the other either. They are just too small. The only proof is when they don’t hatch 7-10 days later.  Therefore, the best practice is to remove them from the hair.

You can use the nit comb as often as you'd like. After an infestation, it's a good idea to perform head checks for 7-10 days post treatment. If you continue to find nits, keep combing until you no longer find any.

Lice lay nits (eggs) close to the scalp and they will hatch within 7-10 days. If you see nits several inches down the hair strand they have most likely already hatched. If you see nits but no lice crawling in your hair, then the nits may be dead and you may not need to treat again for head lice. These leftover nits can be removed with a nit comb to be safe.

It is not uncommon to still find nits but no lice in the hair after treatment. Nits are easy to miss.

The nits (eggs) are attached to the hair shaft by a thick secretion the louse uses, almost like a super glue.  If the comb is not doing the trick because your daughter’s hair is too fine, you can also use your finger nails to pull them out. 

However, if your daughter’s school does NOT have a “no nit policy” you don’t necessarily have to remove all of the nits.  If you used the treatment according to the directions, and the head and scalp was fully saturated in the product, any lice or nits in her hair should be dead. 

If you do not comb out the nits, they will stay attached to the hair shaft. Eventually they will grow out with the hair, but they will not detach on their own.

Lice on furniture can be cleaned by vacuumingVacuuming is the best method of removing lice on furniture. A thorough vaccuum cleaning will pick up anything that may have fallen onto the mattress.

Scabies are different than head liceNo, Licefreee has not been tested to be an effective scabies treatment. You should consult a physician or pharmacist for proper treatment.

Head lice require a live, human host in order to feed and survive. However, lice may become dislodged or crawl from the head onto toys or stuffed animals when in close contact with your child. It is recommended that such items be placed in a plastic bag and tightly sealed for 10-14 days.

No, human lice do not typically affect pets. In fact, lice are host-specific.

As Licefreee® products are only indicated for use on lice, we would recommend contacting a doctor for more information on bed bugs.

No. Animal lice do not affect humans and vice versa. The type of lice that affect birds and the type that affect humans are different species, and host specific.

Although it is likely that closing up the trailer for that amount of time in extreme heat would probably kill anything inside, we cannot be sure. Therefore, we'd recommend waiting the suggested 14 days a nit can survive off of the human head.

It is unlikely, as ocean water does not have a high enough concentration of salt nor does it provide a proper delivery method to effectively kill head lice and nits. Ocean salt water has not been tested by Tec Labs to be proven effective.

It is unlikely; head lice need hair to grip on to and to attach their eggs to. However, head lice have been known to infest facial hair such as: eyebrows, beards, even eyelashes.
