Hi my little boy has only been back in school for 3 days and he has come home with head Lice, he's in yr1, he has short back and sides. I would like some advice pls, best shampoos conditioners or even hair gel I could be using to prevent the lice, other than shaving his hair (which I won't do) I'm not sure what else I can do, my other son is 8 and he has the same problems but at the minute he seems all clear, it's only a small problem but it is really stressing me out. Thanks you x
