I'm doing a course of 3 months 2 times a year in recent years, in association with the Fall Klorane Klorane shampoo and fall arrest force cure. Given the state of my hair - receding hairline and baldness visible - in fact I do not want to take any risks over and I do my best. And I am fully satisfied, the 3 products together: no more hair loss (I'm shot, no hair in my hands) and more beautiful hair, then at certain times I count the dozens hair in my hands . Perhaps one of three treatments would be enough, but I do not want to take any risks, so 3. By cons, at home, it does not push the missing hair or makes thicker existing hair (I have very fine hair), but at least it stopped the bleeding. There is also always the possibility of finding cure Oenobiol with 1 month free (I've always bought like that anyway).
