Non-toxic daily defense against lice. Use it in place of your regular shampoo.

About Lice Defense Daily Shampoo


Children can be exposed to head lice during school outbreaks, playdates, sleepovers, camp, or really anytime that there is head-to-head contact with others. Siblings and parents are at risk if a child in the family is being treated. Itching symptoms, if they appear at all, typically don’t begin until 2-4 weeks after an infestation has begun. This means that a person with head lice has potentially been sharing those lice for weeks before their own infestation is detected.

Perhaps you received a letter from school indicating head lice were identified in the classroom. Maybe a relative called after a family get together apologetically telling you that they discovered their child had lice during the time they were playing with your children. What can a parent do after their child has been potentially exposed to head lice?

Vamousse Lice Defense: A proactive daily step against head lice

Vamousse Lice Defense was designed to eliminate ongoing worry after exposure to head lice. Always check for an infestation first, and use Vamousse Lice Treatment if lice or eggs are found. If you are still concerned that exposure may have occurred, you can take action now rather than waiting for an infestation to be detected.

Vamousse Lice Defense is a gentle, daily shampoo to defend against a lice infestation – simply use it in place of your everyday shampoo. It’s designed to kill lice (as shown in lab studies) with repeated, routine use for 10-14 days. It’s safe, non-toxic and pesticide-free. Vamousse Lice Defense daily shampoo is great for use by the whole family:

  • During lice outbreaks at school
  • During and after summer camp
  • After sleepovers
  • When treating a sibling
  • While at risk of repeat lice exposure – helping to avoid the risk of re-infestation

Vamousse Lice Defense is safe for children 2 years and older, and is available over the counter in retail pharmacies and online.

How it Works

Vamousse Lice Defense is designed to be a swap in your child’s normal routine, without adding any bathing or grooming steps. This shampoo starts working on contact to kill lice, yet its gentle formula leaves hair soft and manageable, And because it’s pesticide-free, it has no pesticide-resistance issues.

Vamousse Lice Defense is pesticide-free and kills lice using the active ingredients Natrum Muriaticum (sodium chloride) and Eucalyptus Globulus. Vamousse uses a physical mode of action to kill lice. 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.

How to Use

Using Vamousse Lice Defense is as easy as washing your hair. Apply a generous amount of shampoo to wet hair, work into a lather and massage into the scalp. Leave the shampoo in hair for at least 3 minutes; rinse with warm water. Use for 10-14 days following exposure to lice and during treatment of a sibling.

Scientific Results

Vamousse Lice Defense shampoo was tested using internationally recognized ASTM testing protocols. 1 Following these industry standards, the products was tested in the laboratory on body 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. 2


Ten replicates of 50 lice each were performed for both the product and a water control. The test exposed the lice in pouches to Vamousse Lice Defense Shampoo for three minutes, per product instructions, followed by a warm water rinse at the same time daily over seven days. 100% of the treated lice were killed after four consecutive applications. (Please follow product instructions to use daily for at least 10 to 14 days after exposure to kill any lice that may have hatched.)



The following questions are all about Lice Defense Daily Shampoo. Read all FAQs.

How much shampoo do I need to use? The instructions say a ‘generous amount’. Should this be more shampoo than I would typically use?

The amount of shampoo you should use will vary depending on the length, texture and thickness of your hair. Use enough shampoo to allow you to completely lather your scalp and hair, working the shampoo thoroughly throughout the hair with attention to the areas behind the ears, at the nape of the neck, and completely from the root to the tip of the hair.

How long should I leave the shampoo in my hair?

Follow the instructions on the package for best results. Work the shampoo into a lather in wet hair and massage it into the scalp. Leave the shampoo in your hair for at least 3 minutes. Leaving it in longer is not a problem.

Can I use my normal daily shampoo and/or conditioner after shampooing with Vamousse Daily Lice Shampoo?

Yes, you can use your normal daily shampoo or conditioner after you have applied, lathered, waited for at least 3 minutes and then rinsed the Vamousse Daily Lice Shampoo out of your hair. Vamousse does contain a traditional shampoo to clean hair also, so an additional shampoo is not necessary.

Can I continue use my normal hair styling products (sprays, gels, mousse, etc.) during the 10-14 day period of using Vamousse Lice Protection Shampoo?

Yes, you can continue to use your normal hair styling products as desired after shampooing with Vamousse Daily Lice Shampoo.

How long after using Vamousse Daily Lice Shampoo do I have to wait to go swimming?

You can go swimming any time after washing the Vamousse Daily Lice Shampoo out of the hair following the instructions.

Is Vamousse Daily Lice Shampoo safe to use on color treated hair?

Vamousse Daily Lice Shampoo was not designed specifically for color-treated hair. We recommend testing a small, inconspicuous section of your hair before using Vamousse Shampoo if you have color-treated hair. One of the active ingredients is a sodium chloride solution that may decrease the vibrancy of some hair colors.

Can I use this shampoo as my new daily shampoo for longer than 10-14 days?

Yes! The ingredients in Vamousse Shampoo are safe, non-toxic, and pesticide-free. It is gentle for ongoing daily use.

Does Vamousse Shampoo eliminate eggs like Vamousse Treatment does?

Vamousse Shampoo is proven in laboratory studies to kill lice. Following the instructions, continued use for 10-14 days is required to kill any new lice that may have hatched from eggs that existed before you began the Shampoo regimen.

How does Vamousse Shampoo work?

Vamousse Shampoo uses the active ingredient Natrum Muriaticum to kill lice 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.

Can I use Vamousse Defense shampoo on other parts of the body?

Vamousse Lice Defense shampoo is intended for use only on the head, including the scalp and hair. Do not use the product on eyebrows, eyelashes or in the pubic area. See a doctor if lice are present in these areas.
