Male Baldness Info

Now, firstly It is a fact that I am going bald. So yes, I have a form of Alopecia. But what I want to know is; is it just male pattern baldness or is it another form of alopecia?
I am a 22 year old male and my hair has been thinning for about a year at the front of my head. It isn’t a receding hairline as it’s not at the temples.
I have been taking propecia for 3 weeks now and as can be expected I have experienced ‘shedding’, which is a speeding up of hairloss. this all points to it being MBP as propecia would simply do nothing if it wasn’t MPB, right?
The problem is, that the hair from the rest of my head seems to come out too. It doesn’t look any thinner but when I have a shower more seems to be coming out than before. Am I being paranoid?
Family history;
As far as I know my family has no history of any other form of alopecia other than MPB which my uncle has, my thinning seems to be in the same area as his too.
Thank you in Advance.

Hi, I am 27 years old male and I am losing hair since past 5 years, my hair are now thin from the forehead of my scalp to the centre of the head. I just want to know if my hair loss is Alopecia Areata? is there anyway you can tell my hair loss is Alopecia Areata? if its not how how do I know if its genetic? we do have baldness history from my mother side, like my uncle was bald? Please help. THanks
