Hair come out finer and thinner

[Freelancer]

Hi there. I have been losing hair at the front and temple of my head. For several months now, I have noticed that little hair have been growing from both side of the temples. However these little hair come out finer and thinner, and some keep falling out.

Is the little thinner and finer hair a normal thing for male pattern baldness? I mean hair loss due to male pattern baldness would not grow back right? or is it due to something different?

I have been using Rogaine, but i doubt the thinner hair is caused by Rogaine, tho I want to believe that it is.
