Nix Lice Treatment Products

When head lice show up in a household, speed and thoroughness matter. Nix is one of the most recognized names in over-the-counter lice treatment, using permethrin to kill live lice and their eggs so you can stop an infestation before it spreads to the rest of the family. This collection carries Nix products for treating both people and the surfaces around them.

The Nix Lice Treatment Kit pairs a 2 oz. permethrin creme rinse with a fine-tooth nit removal comb — the combination that actually clears an infestation. Permethrin kills the live lice on contact, while the comb lets you methodically remove the nits (eggs) that shampoos alone leave behind. Applied to clean, towel-dried hair and left on for the recommended time, it's a straightforward first line of treatment that parents can use at home.

Lice don't only live on the head, which is why the Nix Lice Treatment for Durable Goods matters. This 5 oz. permethrin spray treats items that can't be washed in hot water — mattresses, upholstered furniture, car seats, helmets, and stuffed toys — killing lice and eggs that may have transferred off the scalp. Using it alongside the treatment kit helps prevent reinfestation, which is the most common reason a lice problem seems to come back.

A common question is whether one treatment is enough. Many households find a second application about a week later helps catch any lice that hatched after the first round, and combing every few days keeps you ahead of the eggs. Between the head treatment kit and the durable-goods spray, this collection covers both parts of a complete lice-elimination routine.
