Our daughter had head lice and we have almost all the funds there are tried, but without success. As a last resort, unfortunately, we have tried K.Laus and that helped immediately after an application the lice were completely gone. We also have Gold spirit forte tried, because I had read in a review that this would be the only way that really helps. The stuff is completely useless, stinks and that it is still highly toxic, I just just heard, when I read the other review of K.Laus. We also got us an electric lice comb, also showed no benefit. Then we are still trying to Repelice, also to no avail and the gängiste means Mosquito is also completely useless. I write this from my own experience and would like to contribute with my review help patients do not have to experiment as long as we did.
