Washing your hair more often does NOT get rid of them-- they like nice clean hair! All the products professional products do NOT work, lice are "immune" to them now. Get yourself a shampoo and conditioner with coconut oil, tea tree oil, or peppermint oil. Get a "junk" conditioner too. Get yourself a lice comb and a VERY good friend. Make sure you have rubbing alcohol, baking soda, vinegar and cooking oil on hand. Get a shower cap just for this. Rinse your hair with vinegar and leave it in, shower cap on for 1/2 hour, then wash out the vinegar. Add the cooking oil, wring out your hair, put the shower cap back on. Leave it in for at least an hour, preferably four, then rinse out the oil. VERY CAREFULLY, put the rubbing alcohol in your hair, let it sit in the shower cap for as long as you can (I recommend a towel over the cap, to make sure it doesn't get in your eyes!). Rinse this out well, scrubbing your scalp. Wash your hair in the shampoo, rinse it out, and mix the baking soda with the conditioner. Wash your hair with this mixture, then rinse it out, and add the vinegar again (this weakens the eggs' hold on your hair). Have your friend use the comb and pick out all the eggs and any bugs that remain. I'm a preschool teacher so I'm familiar with lice. Don't feel guilty... they really like clean hair so you must be a good "target" ;) Good luck! <3
Tea tree oil does work. In moderation. Too much is not good for your scalp. Use olive oil and a few drops of tea tree oil. Saturate hair and let sit for about 15-20 mins. There's a website that'll tell u exactly how to do it. Google it! Also, I use tea tree oil in my children's shampoo. About 8 drops per 12oz. Just to keep the critters away.
My sister-in-law used a product she got at a local beauty supply store for super conditioning on my niece's hair. It comes in a tub and looks like soft margarine. She slathered it on, covered it with a shower cap, and let it sit for about 2 hours. Then shampooed it out. Not only were the lice taken care of (they were suffocated basically), my niece's hair was especially shiny and soft.
