Just wanted to pass this on dd, ds and I have just had our first experience of nits yuck yuck! All of us have very fine hair and this morning I was despairing of getting rid of the little bleeders after having treated last night. On the advice of MN I purchased a Nitty gritty comb and it is fab!! it horrifies me to think how many were still in there having used just a normal nit comb. Well worth the money
