Have your children ever had nits without lice? Is that possible? Lice was going round her class last month and so I checked DD every 3 days with the conditioner and nitty gritty comb for about 2 weeks and nothing. Then last week I found what I thought could be a nit but no lice so I wasn't sure. My mother in law then checked her the following day with nit comb and said she didn't find anything. It's been 5 days and I have checked her again and found again what I think are 2 nits, but no lice. I spray her hair every day with the vosene defence spray but off to buy some treatment just in case.
