Why is my hair falling out so rapidly all of a sudden?

I am 26 years of age. My hair loss is NOT hereditary. Everyone on my mother's side of the family has such a full head of hair. My older brother has zero signs of hair loss. My mom's brothers all have a thick full head of hair. Her dad is somewhat badling but he is like 85.

Ever since I was really young I've had issues with my scalp. My mom says that as a baby, I had a really dry scalp condition. Her english was not the greatest but it sounds like it might have been psoriasis or excema? Anyways for as long as I can remember I've always had a dry scalp and my hair falls out very easily. I have no idea why.

At about the age of 18 I started losing my hair pretty badly, then I quit smoking, started eating healthier, and started taking propecia. Then it basically stopped since then and I've had some new growth. Now for the last 4 months, my hair has started thinning drastically and in the last few weeks, its been ridiculously quick. I have taken picture of my hair every few weeks in the exact same room, same spot, same lighting (to ensure a proper control) and it is thinning so badly.

After I shower, I dry my hair with a towl and theres atleast 50 years. I ran my hand through my hair once over the sink and counted 17 hairs. Thats ONE stroke of the hand. This is definitely not normal. I'm not under any major stress and haven't had any major life style changes.

This is really driving me insane and I'm getting pretty depresses and insecure because of it. Yes yes I know, be proud of who you are blah blah but I simply cannot help how I feel.

I am currently on propecia (finasteride), as well as minoxidyl, and using the revita hair regrowth shampoo.

Is there any suggestions from anyone? I was reading online about an hyperactive thyriod condition, and some of the symptoms of that sound like things I feel every now and then. I plan to get tested for that by a doctor once I get back to North America, but in the meantime, this is really driving me crazy. NOBODY in my family shows
