Constant headlice problem

[sleepyhorse]

Hi

I know when you have kids in school it's inevitable that at some stage they are going to come home with headlice but we cannot seem to shift ours. It's driving me mad not to mention the cost of treating the 2 kids, dh and myself. On this particular occasion this episode has been going on since Xmas and I have treated our hair about 5 times since Xmas with various shampoos, sprays etc and combed all our hair with the little combs they provide. It seems to work for a couple, of days and then they are back again!! I have got very thick and long hair so that's probably not helping.
But just don't know what else to do now! Can anyone advise please!!!!

I use nitty gritty and lots of conditioner.

Ok thanks. Do you wash all your bedding too?

Comb with the nitty gritty and conditioner three times a week for two weeks, then once a week checks after that.

Yes wash pillows
