13yo DD got nits a few months ago and I think we successfully got rid (I treated myself too as I started feeling itchy and even if it was psychosomatic I thought I’d better be safe!). Then at the start of the hols I noticed a few eggs in her hair. I’d been feeling itchy then too and I asked her to check me and she said she could see eggs. So we both treated ourselves and combed with a bit wit comb too (although mine was probably less well combed as I have very tangly curly hair). Today I have noticed another egg on her! We are
going to treat us both again but do you have any failsafe methods??
