Mayo instead of miracle whip for at least 4 hours (plasic on head) rinse it out then rinse with vinegar, this will loosen eggs and get rid of the grease from mayo.. Repeat in 5 to 7 days
Mayonnaise and Vinegar
We recently had head lice and our whole family did each a mayonnaise treatment( w/ some ACV added) on our heads. We covered our hair and head w/ a plastic cap. After 30min - 1 hour we washed it out again. I washed only the pillows thinking we will do a deeper treatment w/ the "real " stuff from the health food store later. But it wasn't even necessary. I bought a metal lice comb and combed our hairs through w/ it every day or every other day until no more lice hatched. ( This was esential) This was so much easier to deal w/than flees( and I have very long hair up to my hips). I only washed the clothes we had worn the last few days( because lice can live for 2 days away from its host), but that was it.
