Due to go on TRT, extremely worried about potential MPB, any advice?

Hi all,

I'm due to go on TRT and I've been reading up on some side-effects Doctor did not mention including the high level of conversion to DHT. This is the first time I've paid any attention to my hair and I'm not sure if I'm generally suffering from MPB or just being paranoid:


Top (this is when I've rummaged up there and pulled hair to one side, last pic is what it looks like naturally): http://imgur.com/a/GRncv

Side (this is when I've forcibly pulled hair back, not naturally like this, but still looks worrying): http://imgur.com/a/5UhJB

Front (seems fine?): http://imgur.com/a/uwNzN


Bit of background: I have maybe 10 hairs on pillows every morning, 20 or more in shower, very stressed, and been on a low calorie diet losing 2 pounds a week. My mum's dad lost all his at 40 and mum's older brother has it.

Some have mentioned it's just a cowlick but I just don't know.
