MPB hairloss: effective to just take Finasteride 1 mg without using Minoxidil whose compliance is hard?

In my opinion, finasteride has the ability to suppress hair loss and cause regrowth. Minoxidil is also able to do this however, I have seen better results with finasteride. There is a small percentage ( approximately 30%))  of people that do not respond to Minoxidil. It should be noted that if you add PRP to the finasteride the results are greatly improved.PRPHAIRMD.COM 

Neither of these medications work for everyone. As they work differently, taking both together is fine as is taking only one. While reasonably effective, Finasteride has a number of unpleasant side effects such as reducing libido in a small percentage of males. In addition you can also use LLLT.  The most effective treatment for male pattern baldness is PRP.

Finastride and minoxidil all have the potential to help. But the answer to your question really comes down to mathematics and statistical chances of helping. If I were to bet, you will achieve similar final outcome on finasteride alone compared to finasteride + minoxidil. Of course, there is a small chance you will achieve better results with the combination of the two and studies have shown this too. But the fact that you are using finasteride gives you the very best odds to preserve hair.

Yes, most males will have a much better response to finasteride than minoxidil. They work through different pathways.

The best treatment for MPB is finasteride. In India many doctors are prescribing oral minoxidil which I am told works well.
