I have been using minoxidil (twice a day) and Propecia (1,25 mg) every day for 4 months. Before I started to use it, I cleary shaved my hair. After 3 months I got extremely nice and thick hair. I did'nt have any hair loss. But now my hair have got longer and have startet to get hair loss again. I dont know the reasons, because the cure have worked extremely well for 4 months now. I have used shampo with silicone. So maybe that Can be a problem for the minoxidil to work?
