Some Nix products are labeled for children 1 year and older, while at least one product is labeled for ages 6 years and up.
Nix describes these treatments as pesticide-free and non-toxic. Product notes commonly state "100% Pesticide-Free" and list "Health Facts: Non-Toxic."
The Nix Ultra all-in-one shampoo formulations state they treat and clean hair in 10 minutes with a one-step application.
Kits commonly include a lice-removal comb. Many boxed kits pair that comb with a treatment shampoo plus either a home spray or a daily leave-in prevention spray.
The prevention leave-in spray is described as containing a blend of essential oils, specifically listing rosemary, citronella, and lemongrass.
