Bald Patch : Bigger, shiny and Relentless (with pics)

[shri1026]

I am 22 year old asian (INDIA) and suffering from MPB. I am currently Norwood 3. Also 7 months before I was suffering from Telogen Effilivium which lasted for 2 months. Scared of getting bald just like my two older brothers who have Horshoe pattern on their scalp, I took the extreme step--> I started Propecia medication. Doctors refused to give me prescription. So I am self-medicating. I am on it for 5 months and currently no side effects so far but also there is no visible improvement so far. I am thining at vertex and totally bald at temples..
My current plan is to give minox a shot after 8 months on finasteride only if there is no visible improvement otherwise I will stay on finasteride.

This will be my thread where I will keep updating every 3 months.

But for now can you please tell me for how long finasteride can maintain my hair.
Do doctors promise a cure for mpb in next five years?
Also I want to fill that gap in vertex, temples are there are any other medications other than propecia and minox?
baldness gene is inherited from whom mostly ? My maternal grandfather was bald but my dad's father not. My dad is not bald.I got my dad's hair same pattern,texture . Does it mean my hair will remain as it is without further progression?
I am more concerned about my vertex, I usually comb over my temple as shown in pic.
