Not sure if MPB or something more?

For the past year I've been losing hair frequently, not only from the crown which is where I've lost the most but sides and hairline. What has me confused is that I've been having irritation all around my scalp problems, from the crown to the back and sides. It's gotten to the point where my scalp will itch, dry out, have blemishes and become very red. What makes this worse is I have OCD and one of my problems is I'm a picker, I pick at everything and so when my scalp itches and dries out I pick at it causing scabs.

At one point I thought I was losing my hair because of that and that it would grow back, but even after my dermatologist put me on Ketoconazole 2% (Generic for Nizoral) it would only heal my scalp for a short while before it becomes irritated again. I'm not sure if this is a fungus or something else and whether it's causing my hair to fall out or if it's only speeding up the what's already happening.

What also has me concerned is that my doctor first prescribed my 2% Nizoral and told me to use it everyday, which I did until the scabs went away, now I use it only as needed when my head starts to irritate me again, but I'm afraid I caused some damage when I used it 5 days in a row.

Now I'm contemplating starting Rogaine and Nizoral every 3 days, but I'm not sure if it'll help or reverse anything. I'm afraid of using Propecia because of people saying it has permanent side effects.

Here's 2 pictures, one is a regular shot of my hair, and another is close up. They were taken at the same time.
