The babies have been born, there are tiny live bugs on her head.
Go to headlice.org for some support and good advice. They are factual and not old wives tales.
Head lice are everywhere and almost everyone has them or has had them. They like clean people so in a sort of painful way it is a compliment they get on her. It says you keep her clean.
Here is my rountine:
Kids in school or child care I do this regularly. It is routine to us now.
I put the 8 yr. old who had thick waist length hair in the shower and wash her hair with regular shampoo very very well twice. Then I condition it and comb out the tangles. I hand several wide tooth combs on hooks in the shower for just this reason.
Then I rinse her hair very well. I don't towel dry it much, I want it to stay pretty wet.
I sit her down in front of me in a little tykes chair and section off her hair into 4-6 different areas. Then clip them off tightly against the head so they won't dry.
I take one section and using a rat tail comb with narrow spaced tines I comb and intently examine about a 3" by 1/8" section. I look at the hair using a magnifying head gear. A table top magnifying lamp or glass can be used but I find that the head gear frees up both of my hands.
I use a natural bristle brush too, it smooths the hair shaft out all the way to the end and a nit or bug is very obvious. I take my time. A shadow or dark spot means a large bug, I take the bug out using tweezers or some other item with an edge. It will be moving very slowly since the water stuns them and pretty much makes them go to sleep. They are easy pickings when the hair is saturated wet. Almost dripping.
Once you remove the bug you can drop it into a cup of regular water, it will drown, or smash it in a bowl. The kids like me to do that so they can see them.
I don't often find bugs because I am diligent about checking hair every few days. It is our routine any time the kids take a bath. It is pretty calming to sit and have your hair messed with. Although they are sitting in the living room in a towel with drippy went hair it is pretty relaxing.
If I find a black nit, it has a baby in it, I often just use my nails and force the nit to slid down the shaft of hair and drop the egg into the water too. If it is white then a tiny little new baby is somewhere. It needs blood to live on so it may be hard to find.
It takes me maybe 30 minutes to do her hair because I am used to doing it. She sits still and is patient now. It was hard at first due to sitting with her head leaned back for me to get to the top or leaned over for me to get to the lowest point in the back. It takes patience on both parties sides.
Sometimes my back and neck get to cramping and I can get annoying but then I remember she is the one who is having bugs on her head and then I can feel more compassion.
I don't often find critters or nits since I check often but when I do I do NOT use a pesticide shampoo. They are poison and I am allergic to the plant that is used to make it.
If you are seriously infested I would suggest calling the doc and asking for some Lindane Cream, you put it on clean dry hair and leave it for about 10 hours then wash it out. It is very low dose and works well to prevent them afterwards too.
