  1. Start with DRY hair
  2. Separate hair into 3-4 sections with clips
  3. Shake can well
  4. Part a section of hair into a 1-inch section, focus the nozzle tip at the scalp and apply a generous amount of mousse along the length of the hair
  5. Pay special attention to nape of neck and behind ears
  6. Saturate all hair and scalp, massaging the mousse to break down the foam, thoroughly soaking the hair. To be effective all lice and nits must be contacted. Depending on length of hair, the full can may be needed.
  7. Repeat process until all sections of hair are saturated and wait 15 minutes

Remove lice and eggs (nits):

  1. Although dead, nits remain attached to the hair
  2. After 15-minute treatment, use enclosed comb, to remove dead lice and nits from the wet hair
  3. Working with a 1-inch section of hair, insert the comb against the scalp, and pull through to the end, wiping on a disposable paper towel after each stroke
  4. If hair dries, apply more product to ease combing
  5. Repeat combing if necessary
  6. Shampoo and towel dry hair

Vamousse may be repeated as needed. Children under 2 years: ask a doctor.

How it Works

Kills lice and eggs in 1 treatment

Vamousse Lice Treatment is pesticide-free and kills head lice and eggs by dehydration using the active ingredient Natrum Muriaticum (sodium chloride). Since traditional lice treatments kill adult lice using a pesticide-based neurotoxin, they have limited or no ability to kill yet undeveloped eggs (nits). This means a second treatment is part of the instructions, in order to kill lice as they hatch 7 – 10 days later, before an infestation can be ended.

Vamousse uses a different mode of action to kill lice and eggs both in the same application. The protective lipid layer of the adult lice is compromised by the advanced formulation to rapidly deliver the active ingredient to the louse, causing a rupture of the intestinal tract followed by dehydration. Eggs are similarly dehydrated, rendering them no longer viable.

Kills super lice

Studies have identified strains of head lice in some U.S. regions that have become increasingly resistant to pyrethrins and permethrin, the active pesticide ingredients in most over-the-counter head lice treatments. These lice have been called super lice since they are harder to kill with traditional pesticide-based products.

Vamousse Lice Treatment is pesticide-free and relies on active ingredient Natrum Muriaticum (sodium chloride). Because it’s pesticide-free, Vamousse has no pesticide-resistance issues. Vamousse has been proven effective against super lice in a clinical trial.

Scientific Results

Clinically proven

Vamousse Lice Treatment is clinically proven to kill both lice and eggs in one treatment – even super lice.1 It works by compromising the outer protective layer of lice and their eggs, allowing exposure to the active ingredient, Natrum Muriaticum (sodium chloride). This ingredient kills by dehydration and osmotic stress, leading to gut rupture.2 Read more about this physical mode of action and clinical trial results here.

Scientific studies

Vamousse Lice Treatment was tested using internationally recognized ASTM testing protocols.Following these industry standards, the products were tested in the laboratory on body lice, head lice and head lice eggs collected from volunteers in South Florida. Lice in this geographic area have been extensively documented to have developed genetic resistance (99%) to the traditional lice treatment active ingredients, pyrethrin, and permethrin, commonly in products like Rid® Lice Killing Shampoo and Nix® Permethrin Cream Rinse. 4


Six replicates of 10 lice each were performed [for both the product and control]. The test exposed the lice to Vamousse Lice Treatment for 15 minutes, per product instructions, followed by a warm water rinse. 100% of treated lice were confirmed dead 24 hours after this single application.



Vamousse Treatment has been clinically proven to kill BOTH lice and their eggs (read more about how it works here). For best results, shake the Treatment can well prior to use and fully saturate the hair and scalp to ensure ALL lice and eggs come into contact with the product and remain in contact for 15 minutes.

Vamousse Treatment uses the active ingredient Natrum Muriaticum to kill lice and eggs by dehydration. The unique formula uses an innovative technology to remove the outer protective layer of lice and their eggs, optimizing the activity of the active ingredient to dehydrate lice, ultimately resulting in death.

“Super lice” is a term being used to describe strains of head lice identified in many states in the U.S. that have become genetically resistant to the pesticide-based active ingredients (permethrin and pyrethroids) used in many over-the-counter head lice products. Vamousse Treatment is pesticide-free and therefore has no pesticide resistance. Regardless of where you live, an effective, pesticide-free treatment is a very practical option and available over-the-counter without a prescription.

Your quickest option will be to return the product to the store for a refund or exchange, if another box with a comb is available on the shelf. Alternately, we will be happy to mail you a comb. Please note that this may take up to 2 days to arrive, however. Please contact us at 1-855-373-7210 if you want to report the missing comb and request a replacement.

Vamousse needs to be in contact with all lice and eggs for 15 minutes, however, if you need to leave it on longer for any reason you may.

Vamousse contains no pesticides, so it can be applied as often as needed without a waiting period to treat a reinfestation or any lice or eggs missed during a prior treatment.

Vamousse Treatment has no expiration date. You will see a sequence of letters and numbers printed on the bottom of the mousse can that sometimes is mistaken for an expiration date. This code is a manufacturing lot/batch code, not an expiration date.

Vamousse does not remove the nits. Due to the strength of the “glue” that lice use to attach their eggs to the hair shaft, even dead eggs/nits will remain attached after treatment. Following the instructions, use the Vamousse lice comb, included in the package, to remove dead lice and nits.

It is possible that the product did not contact with ALL of the lice and eggs. For best results, the treatment canister must be shaken well prior to use and ALL lice and eggs must come into contact with the treatment by fully saturating the hair and scalp for 15 minutes. Ensure that areas behind the ears, at the nape of the neck, and down to the roots remain wet throughout the treatment. And keep in mind that even dead nits/eggs can remain attached after treatment.

As a reminder, use one whole can of treatment per person and make sure the hair and scalp are completely saturated throughout the 15-minute treatment period. Vamousse must come in contact with all lice and eggs to be effective. Be sure that you shake the mousse can well before application. If hair is becoming dry before you complete the application and begin to comb, apply more product to the hair and scalp. Follow the instructions on the pamphlet included in the box to ensure you haven’t missed any steps. Use the included Vamousse lice comb to thoroughly eliminate dead lice and nits following treatment to ensure maximum efficacy.  And keep in mind that even dead nits/eggs can remain attached after treatment.
