Kidnapping baby headers is an unpleasant worry occasionally associated with visiting a school or school. These parasites may also occur in adults. Conventional shampoos on lice do not help, they are more resistant to chemistry. Against all, the essential oils of tee tree, aniseed, coconut, eucalyptus, rosemary, thyme, cinnamon, parsley or ylang-ylang are excellent. It is necessary to test which is best for the lice, because the lice are very resistant to the means that have already been used. There is nothing more to change.
