Its just no fun, no matter how you look at it, but it may work. But like I said saturate the hair
and scalp with mayo then pile the hair
on top of the head, put a plastic bag over her head, i use the bags that the grocery stores give you, I put it on the head cover the tips of the ears with the bag, gather it at the nape of the neck and use a rubberband, or a clippy to hold it into place. Keep the bag on her head for atleast 2 hours, so that it hopefully smothers the lice.
