How to kill lice eggs from hair


Killing Adult Head Lice

1
Exterminate all adult lice. Removing the nits from the hair of the person affected won't make a difference if adult lice are still able to breed. As long as there are adult lice, new batches of eggs will continue to appear on the hair. These additional eggs will then hatch into more lice, which in turn will lay more eggs. This unending cycle is not broken until all adult lice have been killed.[1]
Submerging your hair underwater for an extended period of time will not kill or drown lice. Studies show that the lice simply cling to the hair or scalp while underwater and can survive underwater for several hours. The chlorine in pool water, unfortunately, is also not strong enough to kill lice. [2]
To kill adult lice, wash your hair, or that of the person affected, with over-the-counter lice shampoo. In extreme cases of head lice, prescription-strength head lice shampoo is also available.

2
Try a prescription shampoo. One option is Pyrethrum, which comes from chrysanthemum flowers that harbor natural insecticides called pyrethrins. Pyrethrins attack lice’s nervous systems, though some lice are now resistant to the toxin.[3]
Apply the shampoo to dry hair. Then, wait ten minutes, add water, work into a lather, and rinse. You should then try to remove nits and repeat the process seven to 10 days later, to kill any remaining bugs.

Suffocate the live lice as an alternative. Although there are few clinical studies on its effectiveness, some people believe that you can kill lice by suffocation. The way this works is that certain products, they argue, clog the bugs’ breathing holes. Lice can survive for hours without breathing, but eventually they will die.[4]
Try a petroleum jelly like Vaseline. Apply the jelly to your hair and scalp thickly. The jelly must remain for up to eight hours to kill, and you should wear a shower cap to restrict air flow. Keep in mind that Vaseline will be very hard to remove and will not kill the nits.
Some people also advocate the use of common olive oil. Again, some claim that the oil plugs the insects’ breathing holes and suffocates them. Like Vaseline, you should apply the oil to your hair and scalp, don a shower cap, and wait about eight hours before cleaning the oil. As a bonus, the oil should loosen the nits from your hair and make it easier to remove them.
Mayonnaise may work as well. Mayo contains a large amount of oil, which seems to be the suffocating ingredient. Apply to your hair and scalp like Vaseline and olive oil. Anecdotal evidence suggests that regular, high fat mayonnaise works best.

4
Prepare your nit-removal area. Sit down in an area with plenty of natural or artificial light. This will make it easier the person removing the nits to actually see them, as they are small and are glued to the hair near the scalp.[8] Additionally, drape a towel over your shoulders to catch any hair or nits that fall off.

Removing Nits with Vinegar


1
Rinse your hair with water and vinegar. Nit eggs are covered in a sticky substance which binds them to human hair follicles. Vinegar has been found to contain chemicals that dissolve this substance, preventing nits from maintaining their grip on human hair.[9]
While kneeling in front of a bathtub, place your head under the faucet. Turn on the warm water and thoroughly dampen your hair. Then, turn off the water and, while still kneeling, pour a large amount of vinegar over your head. Make sure that all strands are coated with the liquid. Then use warm water to rinse your hair.
Alternatively, fill a sink with 1:1 parts of water and vinegar. Submerge your hair in the sink entirely, either by dipping your head forward or dipping it backward into the solution.
Detangle with a leave-in conditioner and normal brush. Try to get your hair entirely detangled, so that combing with a nit brush is easy and painless.


2
Begin to comb out the nits. If you are the one affected by lice, then you will need the help of another person. They'll need a metal nit comb — a fine-toothed and rigid comb that is better at removing nits than a plastic comb. You should be able to buy a nit comb at most pharmacies for under $10. They can use a magnifying lens if possible to search for hard-to-see nits.
A large number of nits could have been rinsed out of your hair during the vinegar application. However, there will likely still be eggs clinging to the dampened strands. Working with one small section of hair at a time — about the width of the nit comb — your helper should carefully comb through your entire head.
