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.

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 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.

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.

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.

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.

Yes! The ingredients in Vamousse Shampoo are pesticide-free. It is gentle for ongoing daily use. You may also use your favorite conditioner after shampooing.

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.

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.

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.
