Should I just start taking finasteride?

Should I just start taking finasteride without consulting a dermat? I mean, I see...posts here..and most of them have the same problem as me. Same hairline reciding, same hair thinning, dandruff and dry and flaky scalp. And most of them take finasteride for hairfall and these issues. So, I was thinking should I also just start taking min and fin? I mean, I have used minoxidil before, didn't work. So, I thought about trying the combo. I am a little bit sceptical about visiting a dermat and I also do not get the time nor do I know good dermats around where I live currently, which is Bangalore. So, can anyone please advice me on this or suggest some good dermats? Thank you.
