It's for my daughter who has long curly and thick hair: she is very happy because the product smells apple and is not unpleasant, easy to coat. A priori it was effective from the 1st application because she made a second for safety and there was nothing left. In addition, because of the volume of her hair I had taken the 200 ml and it has not used at all, even in 2 + for her boyfriend who has short hair it! Let's see if it is complete and if these awful little creatures do not come back, but very happy!
