Currently treating daughter. How on earth do you get rid of the eggs that are stuck to hair? We've got rid of all the lice crawling about but when you put a nit comb through the eggs they don't come out...even when I try with fingers some of the eggs are stuck solid to hair. I've read posts on here saying put conditioner on first but is this just for removing lice? It's like they are glued to the hair and some eggs are too small!
