Easy, inexpensive remedy that completely eliminated lice after 3 treatments. Mix equal parts of 91% rubbing alcohol and white vinegar into a spray bottle. Add 1 drop of tea tree oil for every fluid ounce of mixture. 3-4 ounces will be sufficient to treat a head of long hair. Thoroughly wet hair with mixture, and comb out in sections with metal nit comb. After every few strokes, rinse the comb in a container of water to see what is coming out of the hair and to track progress. Wash and condition hair afterwards with coconut based products. Blow dry hair on high heat. Repeat treatment every other day to break the reproduction cycle until lice are gone.
Pure Alcohol, Aka Rubbing Alcohol
Hello, in Greece in order to deal with lice we wet the hair with a very common disinfectant, a form of pure ethanol, the name here is "pure alcohol", I think the name in UK is "surgical spirit", is the kind of alcohol or ethanol we use for disinfecting hands, in its clearest transparent white form. As this, in many countries, is considered alcohol it might have a high price, so we can used also a mixed an unedible- form of that with glycerine etc - very cheap.
We wet the hair with it, put a towel for 20 min and repeat every day in the beginning for 3 days and then every other day. The lice suffocate and die instantly. They cannot develop resistance to this as even larger insects (cockroaches) also suffocate and die instantly if you spilt ethanol on them.
As the normal use for this is for disinfection and the pure form is used in all alcoholic beverages, well I guess is not very bad to put lets say a very strong vodka in your hair.
