Available sizes vary by product; the listings show bottles/kits in 8.4 fl oz, 4 fl oz, and 10 fl oz across the treatments and kits shown.
Most kits include a lice treatment shampoo or solution and a lice removal comb. Some kits also add a home/room lice-killing spray or a daily leave-in prevention spray for hair.
The all-in-one Nix shampoo/treatment is described as a one-step application that treats and cleanses hair in about 10 minutes.
Age labeling varies by product: some listings are labeled for children 1 year and up, while at least one listing is labeled 6 years and up. Check the specific product label for the exact age recommendation.
Product descriptions state the treatments are pesticide-free and non-toxic. They say the products work by suffocating lice — including pesticide-resistant “superlice” — rather than using traditional chemical pesticides.
Descriptions state the home lice-killing spray kills lice and bedbugs on furniture and bedding and is effective for up to 4 weeks.
Even where some descriptions say lice can be removed without combing, the kits still include a lice removal comb to assist with removing lice and eggs after treatment.
