Why does salt water kill lice?
Salt and salt water will have no effect on lice eggs.

Lice eggs have a tough outer shell and salt can not penetrate through it to kill the nymph (baby bug) inside.

New eggs are attached to the hair shaft very close to the scalp. Eggs that still contain a louse embryo are brownish in color, while the empty egg shells are white to grey.
How many lice are in one egg?
After mating, the adult female louse can produce five to six eggs per day for 30 days (8), each in a shell (a nit) that is ‘glued’ to the hair shaft near the scalp (5,6). The eggs hatch nine to 10 days later into nymphs that molt several times over the next nine to 15 days to become adult head lice (5).
How do you remove lice eggs from hair?
To remove lice and nits by hand, use a fine-tooth comb on wet, conditioned hair every 3–4 days for 3 weeks after the last live louse was seen. Go through small sections of hair at a time. Wetting the hair temporarily stops the lice from moving, and the conditioner makes it easier to get a comb through the hair.
What kills lice eggs naturally?
Parents can either mix three to five drops of tea tree oil to every ounce of shampoo, or combine three tablespoons of carrier oil — like olive or coconut — with a teaspoon of tea tree oil and apply to infested hair for 30 to 40 minutes.

How long does it take to suffocate lice with olive oil?
In order to fully suffocate head lice using olive oil, you need to completely saturate the hair and leave it on for up to eight hours. Because it only kills active lice and not the eggs themselves, treatment must be repeated until all lice have been removed successfully. This can go on for days or weeks!
