No, none of these kill lice. Lice go into a state of “suspended animation” when submerged in water. This makes them able to hold their breath for several hours, so you can’t drown them easily. Chlorine and hair dye do nothing to kill lice. However, if you dye your hair when you have lice, the hair dye will stain the nits (eggs) and will make them even harder to see! Hair gel, mousse, hairspray, and other styling products do not do anything to kill lice or prevent you from getting lice.
