Sounds like a very stupid simple question but when you are preparing to go looking through your DCs hair for lice, do you wash (ie. shampoo) their hair first, then apply conditioner and then comb through with a Nitty Gritty comb, OR just apply a dollop of conditioner to dry hair, then comb and then wash it thoroughly afterwards...?
DD is 10 and has never had nits before. Came home from Guide camp last Thursday and now has lice.
So tonight - having sorted her yesterday and this morning with Hedrin and combing - I am starting on two DSs, DH and me...deep deep joy...

Any advice would be gratefully received. TIA.
