do i have to take anti-androgen along with DUT to get good result

Actually i am taking generic fin for 2.5 months , i can feel than my hair loss is some what stopped but still my hair are thin in front and in crown.I stay in india and i am not using minoxidil so for, because it is really hard for me to apply it in lotion form , so can i use spray form of minoxidil?

i wanted to shift to DUT , because many of them saying that fin will loose its effectiveness. Some dut users swear by taking an anti-androgen along with dut. They have been on dut for about 6 months and have got good results. They only use an anti-androgen probably once a week.
