Is there a good way to kill lice eggs?

Vinegar wash: If you use vinegar (regular, apple cider vinegar or pickling vinegar)as a hair rinse it will soften the glue that holds the nit to the hair & it will separate easier from the shaft.A fine tooth nit come is helpful for this process. It can be repeated daily for a week & may kill active bugs too.

Remedies: Natural remedies for lice include the application of olive oil, mineral oil or mayonnaise to the head/ hair. These oil-based products smother the louse. However, there is no research to demonstrate treatment efficacy.

Wash clothing or linens in HOT Water. Soak personal items like combs or brushes in HOT water for at least 10 minutes (or throw them out if this is an option). Vacuum floors, carpets, mattresses, upholstered furniture & your vehicles.

Ive tried every possible lice medicine and visited doctors yet no kind of medication is helping, and the eggs are more common than lice, what to do?

Several things: If you rinse your hair daily with copious amounts of a stiff vinegar,( pickling vinegar does well), this can loosen the eggs attachment to hair. Combing the eggs out with a nit comb will then have more success.If you do that for a week & then try the OTC product it may work better.If not there are some prescription meds for the resistant lice.
