Hi, so I have been diffuse thinning since like 17 (I am 20 right now) and only unfortunately this year I got on the medications as they are not easy to find here (Turkey) and to be honest I was a bit dumb believing the situation has stabilized etc. Long story short, I picked up the fight again so I began using oral min 2.5mg+oral dut 0.5mg (daily) and want to add 1.25mg fin to my stack as I have been using dut for only 10 days and it takes time for dut to fully take effect. Is this a sound idea, chatgpt (which I cannot trust) says yes. I will take fin 1.25mg+dut 0.5mg+oral min 2.5mg and will drop fin after 1-2 months pass where dut takes effect. Don’t tell me to ask this to a doctor, dermatologists here are unqualified as duck for AGA and some even have no damn idea about "5α-Reductase Inhibitor"s being used for hair loss 
More “qualified” ones barely prescribe finasteride and that is only in topical form that is nowhere near effective
you can just frontload dut, there’s a good thread on here about it
