Description
Nix Lice Prevention Daily Leave-In Spray only makes sense in the prevention slot. It is designed for households that want a deterrent routine during outbreaks or after successful treatment, not for families trying to deal with a confirmed active infestation.
That distinction matters more than anything else in the row. The official page is clear that it does not kill lice or eggs and should not replace an actual treatment product when live lice are present.
