Definately comb through with lots of conditioner and a nit comb.The cheaper combs don't get them all,but the Nitty Gritty one is very good.It doesn't kill them,but if you get the eggs out,and this comb does,there'll be nothing to hatch,so you get rid of them that way.Its time consuming,so you can't get rid over night,and of course you get the little blighters trying to crawl away,maybe onto you,I had four on my t shirt which were probaly trying to find a home on me,so I either wash them down the sink or wipe them off the comb onto white kitchen towel so I know they're done.
My Grandad used to tell us that his mother used to "crack" them with her thumbnali as she got them out.They didn't have lotions in those days.
