Well we managed to go 12 years without seeing one and she has eventually succumbed 
I am horrified and cannot stop scratching myself. The day before yesterday I did all of her hair with Numark head lice treatment 1% w/w cutaneous emulsion permethrin 1%. So we combed all through etc, she has had a shower tonight and I have combed through again and there are still little buggers in there - and they are moving
Did the box of stuff not work? It said it would kill everything and then it would protect her hair from them for 2 weeks 🤔
Wondering if I should try another solution in 48 hours or just keep going through with a comb?
