A call to dut users for help...

Hi...!!! I dalayed my hair loss by 4 years using finasteride and later dutasteride.for the last seven months I am also on minox. But nothing seems to be working.10 months ago I was shedding thick and healthy hair but now I have been shedding very thin hair. A narrow strip of hair on my mid scalp is seems relatively thick but elsewhere my condition is too worse. The thinning on hairline corners has moved towards crown just with in 2 months. Now I can't see even a strand of healthy hair on my problem area. I am 23 years old and currently on 0.5 mg of dut ( dutas from Dr.Reddy). Shall I switch to dut 2.5 mg now??? Please reply,it would be a great help. Thank you...
