My granddaughter has been dealing with head lice off and on since April. I ve only found the adult lice (6) once, however, I consistently find nits. I have applied otc Nix, Lice free, home solutions, consistently comb outs, washing beddings, pillows, coats, clothing, vacuuming couches etc. Today, after another Lice Free Shampoo hair washing, I found nits again. Not a lot but enough to trouble me as well as my poor granddaughter. I am repeating all the suggested cleaning etc. I am at wits end!!! What else do I do? Is it common to find some nits on our heads? I hope not. This is so stressful and causing us anxiety. Please, any suggestions are greatly appreciated. If there is a charge for this service, please do not respond as I am on social security and money is tight.
