Both dcs caught nits 4 weeks ago. I combed live lice out of their hair - 12 out of 8 year old and 6 out of 6 year old - i treated twice and they are definitely clear now. My head was insanely itchy but couldn't see any lice when using the comb. I wash and straighten every 2 days so probably kept it at a minimum I thought. My head is still bloody itchy after 4 bloody weeks. I have treated myself 4 times. I do have long hair but I see nothing when using the nit comb. Its making me feel ill - am due to get hair cut tomorrow and terrified they will escort me out for being nit ridden. Arrrrrgggh!
