I have been using it for almost 9 months now and new hairs are starting to grow. Hair loss has stopped. The good thing is that it doesn't make the hair greasy, it has a very pleasant scent, and with the 200 ml in each bottle, it lasts for almost three months with twice a day use. On the downside, the price is a bit high. The same goes for the shampoo. If you can find both of them on sale like I did, get them for around 32 Euros.
