But I know from experience that the real key is to then make sure ALL eggs and any remaining live lice are picked out one by one.
Hence, this is where the term "nit-picking" is derived from.
Head lice eradication can be a frustrating issue to deal with. However, the reason why it's also important to remove the nits is if you don't remove the nits it's difficult to determine if you have a re-infestation of head lice. So try to remove as many of the nits as possible.
It's also very important to do some environmental treatment as well. So the mattress on the beds should be vacuumed and then turned over. All the clothes, bedding, towels should be washed. The car and furniture upholstery should be vacuumed. I also recommend putting the stuffed animals in plastic bags and tie them tight for two weeks. Don't forgot to boil your combs and brushes in hot water or buy new ones.
Then after you've done all this recheck everyone's hair every 10 days to two weeks to make sure there's no re-infestation. Regarding your hair, I don't know of any lice salon, do you have a friend who can help check your hair?
Btw, I've heard of a lot of home remedies such as mayo treatment, vinegar rinses, but the one I think is most effective is using some hair oil daily because the oily hair makes it difficult for the lice to adhere to the hair shaft.
I don't recommend spraying of furniture with the lice sprays.
