The dreaded lice problem

I have three daughters who all have long hair. They shower everyday as well as have a clean home, clean bed. I painstakingly go through there hair to try and get it all out. I live in a humid area lice is a normal thing here. But it is so annoying and I end up catching it too. I don't want to put chemicals in my children's hair as well as its costly to keep buying lice solutions. Any home remedies? When I was a kid my father actually shaved my head so that the problem was solved. I do not think that I will use his solution on my girls.

I heard that one should always put a few drops of tea tree oil in the kids shampoo, which should be a deterrent for lice. I think a stronger amount of the oil is used to get rid of lice, if you have them.

I always love the natural remedies, it's so amazing when natural products actually work better than medicines and chemicals, etc.

My daughter had gotten lice and I did not know it so she had a really bad case of it. I tried using the chemical solutions that they sell in the drug stores twice to no avail. I did some research online and found a great treatment for it.
Supplies:
shower cap or you can use a plastic bad
listerine mouthwash
white vinegar
nit comb
Completely saturate hair with mouthwash making sure that you get all the way to the scalp. Cover the head with the shower cap or bag for 1 hour.
Rinse hair
Completely saturate hair with white vinegar the same as with the mouthwash Cover head for another hour.
Rinse then use the nit comb to take out the nits. This will be easy because the vinegar loosens the glue that the nits are stuck to the hair with.
This method worked for my daughter. As a preventative, I would use tea tree oil or coconut shampoo. I had some coconut milk product that I would put in my daughters hair every day and she never got it again. I have heard that blow drying your hair will help to kill them as well. Lice actually prefer clean air since it is easier to stay on the hair because there are no oils in the hair after shampooing. I only have them wash their hair twice a week and this will also help prevent catching lice. They are not able to grasp the hair because of the oils so they cannot lay their eggs.
I hop this works for you.

I love this suggestion and will try it. I hope it does work too because I can't stand my head itching from it either. Also I avoid chemicals for my kids because well we all know it isn't good for them. Growing up I had a really bad case of lice. My family bought every single product they could to get rid of it problem was it would come back in full force. So sadly to say my father the genious shaved me bald making me look like a cute boy.

I am excited to get started on this and see if it works I will let you know if does and most certainly give you props. I can't stress how hard I try to keep my kids hair rid of those infested little creatures. Thanks again for this home remedy.
