On the plus side: a natural composition, a non-toxic and very delicious smell (I may be wrong, but it looks like a coconut), lice killing very well. Of the minuses: quite thick, so long to apply and economical in use despite the fact that the amount of money is not large, the nits in the mass well removed the comb, but not all, had to shoot some nails and they "click" when pressed, that is, likely to remain alive. After use, I concluded: the head had to smear the thicker, leaving no "reserve" and leave the vehicle at night (in principle, it is recommended as an extreme option in the instructions). Then, I think the effect would be fully as promised. Is complemented by a review. After a week, I note that the effect on the nits 100% even after the first application. Total - content can be stretched 3 application on the head of a child of 8 years. The effect is excellent. Prior to this, with long and thick hair of the child to bring French-toxic vehicle purchased in our pharmacy, I could not.
