I had trouble with my girls getting lice at school both of them with long hair not to mention mine is very long, after tryng the shampoos and cleaning and cleaning the house and ironing beds i found the best thing and it almost gets rid of the nit you only have to pick out a few..what i do is buy extra strength denorex shampoo wet there heads put the shampoo in for 5 mins wash it out and use coconut conditioner and blow dry every other day and the bugs was gone. now they wash there hair with coconut shampoo and conditioner everyday and have had no outbreaks. let me know if you have any luck with this.
