Is it normal to have a crazy shedding on dutasteride even thought you are 8 months in and the hair loss already stopped before?

| started taking Minox and dutasteride about eight months ago first three months I had a crazy shedding then it stopped, regrowth, everything was fine, but now again, the hair starts falling out, anyone experienced that before? Is this just a different phase shedding phase #2 or does that mean hair loss will continue now and dut is too weak?
