Yeah, when my siblings and me were younger we had some special conditioner and a metal comb thing to get rid of them. Not sure how you'll manage to not kill them since they can't live outside your hair anyway?
Nit comb your head 2-3 times a day and make sure that one of them is when your hair is wet. Also, make sure that you disinfect and clean the comb afterwards. That's how I got rid of them when I was younger It might be worth getting someone else to help you with the combing, fresh pair of eyes and all that jazz!
You can buy the medicated stuff for them but it never worked much with me really so I wouldn't recommend them really. Make sure to keep on top of it to make sure that they don't come back!
The actually live outside the hair for a few days so killing them off may well be a great idea. Live lice are bastards to comb out unless your hair is wet as they can crawl away. The dead ones will just comb out without fuss.
You will need to do this regularly, avoid contact with other heads, strip and hot wash bedding, clothes and cushions and try and think of where you may have got them. I had them chronically at school due to lil bros and sister bringing them home.
You have to attack them ruthlessly. I'd say kill the lil ****ers.
I'm a mum and have had plenty of experience of getting rid of those pesky parasites. Over the years head lice have become increasingly resistant to chemical treatments. My advice is to get yourself a Nitty Gritty Nit Comb (the only one that I found actually worked properly). Cover hair with conditioner. Fill sink with water. Comb through your hair and rinse off comb each time you put it through your hair. You will need to do this constantly for 20 mins+. Change water in sink as necessary - you will see the lice and eggs removed fairly easily - until there appear to be no more to remove. Rinse hair. Change and wash your bedding.
You will need to repeat this method every 2 days until there are no more lice and eggs.
theres no way not to kill them really ... they cant live outside of hair for very long ..
not quite sure why you wouldnt want to kill them theyre bloody annonying vermin.
but just use a nit comb, i think theres certain shampoos/sprays whichll kill them aswell but hey ho..
